February 2, 1945The New Craftsmanship for post-war housing
The millions o f new houses which are and will be needed in this country—
“ prefabricated ” and brick built alike— will call for ample supplies o f standardised electrical products o f good design, quality and durability.
The M .E.M . factory is fully equipped to turn out switches, fuseboards,'and other electrical gear immediately the change over from war priorities to peacetime production becomes permissible. By full mechanisation and skilled planning M .E.M . engineers have created the New Craftsmanship which might be described as
quality in quantities.
Quality depends upon good design, good materials and tested construction.
Quantity production is the result o f mechanisation and organisation. The M .E.M . factory is self-contained and self-sufficient. It produces good electrical gear from start to finish— good all through.

Fuel Economy
W
H IL E n o fuel rationing schem e was an n oun ced b y the Ministers o f Fuel an d P ow er and o f P rod u ction a t their conference on M onday, both emphasised in n o uncertain term s that unless there is a 10 per cent, reduction in the cu rrent consum ption b y industry on a volu n ta ry basis, the G overnm ent will be com pelled to issue a direction. A s un
fortu nate as the position m a y b e from the p oin t o f view o f bo th industry an d elec
tricity supply, it is Obvious w ith the load approach in g the m axim um o f 8 400 000 k W , that som ething lias to be done if a general breakdow n o f' the grid system is to b e avoided, and a volun tary cut in con sum ption seems the m ost practical solu
tion.
W ith respect to the G overnm ent threat o f direction, it m ust n ot be overlook ed that there is already a fuel rationing scheme for electricity supply in existence, based u pon the arrangem ents laid dow n in the W h ite Paper on Coal, published on June 3, 1942, though whether the scheme w ould b e efficacious in operation is an oth er matter.
The same W h ite Paper w hich dealt with coal, also brought into being the M inistry o f F u el an d P ow er as an answer to the fuel problem s o f those days, and our present position is evidence o f the success w hich has atended its form ation.
W e said a t the tim e that though the elec
trical in du stry h a d n o liking for the new M inistry it w ould in the national interest, give it full support, and that it has c o n tinued to do w ith ou t stint. Should the M inistry decide to introduce the rationing scheme as laid dow n for current consum p
tion in the 1942 W h ite Paper, however, it m ight be asking too m uch o f the supply industry, for w ith their depleted stalls the operation o f a rationing system o f an y sort is b ey on d the practical ability of m ost undertakings.
N o one is m ore conscious o f the neces
sity for fuel econ om y than the su pply in
dustry, bu t w hether the threat o f a G overnm ent direction w hich has little practical possibility o f bringing a b ou t the desired result is the right w ay to approach the problem is dou btfu l. A com pulsory reduction of consum ption b y industry w ou ld of necessity reduce ou tput, and w ith a tota l war still to be w on such re
du ction is inconceivable. W h at then can be done ?
T h e consum ption of current b y indus
try has increased by over 50. per cent, com pared w ith the pre-war figure, while of the present-day dem and industrial c o n sum ption accoun ts for 70 per cent, o f the total load. In dustry has m ade a gigantic effort to m eet the w ar-production needs of the coun try, and if in so doing its cu r
rent consum ption has increased, surely that was to be expected and is no justi
fication for the Ministers’ threat o f direc
tion.

Littlebrook Power Station
B rief D escrip tio n o f G en eratin g and Sw itchgear A rrangem ents
T
HE Littlebrook power station of theK ent E .P . Co., the foundations for which were com m enced in 1937, was com missioned just after the outbreak of the war. The station has about it much of interest, in particular the 66 and 132 kV switchgear, and the fa ct that the marshy ground on which the station stands was built up to the required level by some 1 000 000 tons of filling, while all structures are carried on piles o f reinforced concrete driven into ballast.
The station has a generating capacity of 120 000 kW , made up of one 60 000 kW B .T -H . 2-cylinder single-exhaust turbo- alternator, for operation at a speed of 1 500 r.p.m ., and generating at 15 k V ; and tw o 2-cylinder, double exhaust Parsons turbo-alternators, each rated at 30 000 k W , for operation at 3 000 r.p.m ., and generating at 13.2 kV. The 60 000 kW machine has five-stage feed heating, with a final temperature of 355 deg. F ., while the tw o 30 000 k W units each has four- stage feed heating, with a final feed pump temperature o f the same value. All machines have 3-pass twin condensers, while the B .T .-H . unit has tw o 3-stage ejectors, one condensate cooled, and the other c .w . cooled. The Parsons machines each has a 3-stage condensate cooled ejector, and a 2-stage unit, c .w . cooled.
The 60 000 kW set is delta-star connected to a 15 /132 kV three-phase transformer rated at 75 MVA, and the 30 000 kW sets are directly-connected to 13.2/66 kV
three-phase transformers, rated at 36.5 MVA.
The boiler capacity comprises three B.
and W . stoker-fired units, and. three p.f.
fired units by International Combustion, Ltd ., each of an evaporative capacity of 256 000 lb ./h r s . m .c.r. for operation at 600 lbs. per sq. in. at 825 deg. F. The B. and W . units are o f the 3-pass vertical headed type, with Bailey water-cooled walls, and double loop-type superheaters arranged in separate h alves; superheat control is by attemporators fitted with Tate automatic control. The stokers are Ward-Leonard controlled, and each boiler unit has tw o forced draught, and two induced draught fans driven by 2-speed Lancashire Dynam o a.c. motors, and two secondary fans driven by a single speed a.c. motor of The same make. The dust collectors are D avidsons’ D -type arranged in tw o groups, each consisting of three collectors, while soot blowing is, in the case o f the furnace, carried out by means of six B. and W . Clyde retractable single blowers operating at 350 lbs. per sq. in .;
in the case of the boiler and superheater by eighteen Diamond m ulti-jet blowers oper
ating at 160 and 100 lbs. per sq. i n . ; and ifor the eoonomisers, three B. and Wt single nozzles, operating at 350' lbs. per sq. in.
The pulverised fuel units, each comprises a four-drum boiler with furnace, water- cooled by Murray fin tubes. The super
heaters are of the Melesco multi-loop type,
Two views of the Reyroll; 66kV switchgear, with the maintenance control panels on the left
The main panel in the control room controlled by desuperheater ,on the Kent
automatic system. Senior twin type econo
misers, two per boiler are installed, to
gether with two i.d ., and two f.d. fans driven by two speed M etrovick a.c.
motors. Soot blowing equipment by the Ivor Power Speciality Co. pro
vides eight single nozzle retractable blowers for each of the furnaces, four multi-jets per superheater, and two multi
jet traversing 'blowers for each economiser.
The pulverising plant in the case of two of the boilers is of the International Com
bustion type LM12, with revolving table feed and a pulveriser comprising a horizon
tal table below two conical rollers, 2 mills per .boiler. Airborne coal from the pul
verisers passes through revolving classi
fiers, vertical shaft driven, through reduc
tion gearing by a variable speed d.c. motor of 7 H.p. with a sp eed: variation o f 200 to 80 r.p.m . The fuel fan, driven by a 125 h . p . a.c. m otor, has a speed variation of 1 470 to 970 r.p.m . The third p .f. boiler has tw o Kennedy horizontal ball mills, with a feeder of the revolving table type.
The pulveriser is driven through worm gearing by a 200 h . p . motor. The fuel fan is o f Keith Blackman design, driven by a 125 h . p . a.c. motor at 1 450/725 r.p.m.
All p .f. boilers have corner firing,’ with oil lighting-up equipment at each corner.
Tw o Wallsend-Howden, pressure type, oil pumping units with thermostatically con
trolled heaters raise the oil temperature to approximately 140 deg. F ., each unit being driven by a I h . p . motor.
Flue gases are carried away by two 315 ft. chimneys and Sturtevant electro
static dust precipitators are installed. Ash and dust handling is carried out by hydro
jet equipm ent by Ash Co. Ltd., and the h.p. pumping plant comprises two high pressure, two-stage Medivane pumps, each driven by a 190 h . p . motor capable of sup
plying 1 600 g.p.m . at 120 lbs. per sq, i n . ; the ash pumps are tw o single-stage centri
fugal horizontal spindle type, driven by a 200 H . p . motor.
All water is taken from the Thames.
Coal intake is by rail or by water trans
port, a side discharge type wagon tippler b y Henry Lees and Co. and a travelling bridge with belt conveyors by Fraser and Chalmers being provided, together with gravity bucket conveyors by R obt.
Dempster and Sons. For handling water- borne coal, two electrically-operated four- motor travelling and balanced luffing type cranes by Stothert and Pitt, Ltd. are in
stalled on the jetty.
In addition to the step-up transformers already referred to as being connected to the alternators, there are also connected to the Parsons sets, two 3 MVA, 13.2/6.15 kV unit transformers, and to the 60 000 k W set a 4 MVA, 6.15 kV unit, all being star-delta solidly connected to the alter
nators. The unit reactors comprise three 6 kV components of 4 per cent, reactance, and 4 000 basic kVA , one per set, all oil- immersed. Three 350 kVA , 6 000/400 V unit auxiliary transformers are provided, together with tw o 45 MVA, 132/66 k V bus
bar interconnectors, star/star and tertiary connected. Tw o 10 MVA, 66/6.15 kV station transformers are also installed.
Switchgear of 66 kV Reyrolle type MS is provided in two separate buildings some
•distance from the main building. This gear, which was among the first of its ty p e to ever, be installed in the country, is of the
94 T H E E LE C TR IC IA N February 2, 1945
low-oil content type, and is operated by compressed air at a‘ pressure o f 60 lbs. per sq. in. ; the rupturing capacity at 66 kV is 2 000 MVA.
Each phase is separately enclosed in earthed metal, and each circuit breaker is pseudo-oil operated. A ll the components Of the three-phase switchgear panel ¡are supported on a bedplate containing three cable chambers, each carrying tw o orifices, into one of which the feeder-side bushing o f the circuit-breaker projects and into the the other the lead-in bushing of the v olt
age transformer. The bus-bar chambers are mounted on the bedplate adjacent to the orifices mentioned, and each chamber form s a bus-bar section comprising a main chamber and an auxiliary chamber arrang
ed for the insertion of a sluice gate, the purpose of which is to provide an earthed barrier between sections during mainten
ance. Three single-phase single breakers are assembled as a three-phase unit with a common tpp-plate and can be isolated by lifting the complete unit vertically. The operating mechanism consists essentially of a piston actuated by compressed air and operating three oil pumps to open and close the m oving contacts of the three single-phase breakers simultaneously.
For isolating the complete three-phase panel, tw o circular pneumatic lifting cylin
ders are m ounted on the bedplate, one round each feeder side orifice on the outer phases only. The panel is held positively, either when isolated or when plugged in, b y means o f mechanically operated locking bolts. The section isolators are operated simultaneously b y hand, and when they are open and the sluice gate is in position they m ay be withdrawn completely from the bus-bar chambers for inspection or maintenance.
The breakers can be controlled from the main control board, or from an emergency control board, or, in the isolated position, from a maintenance control p a n el; electri
cal interlocks ensuring that only one of the operating points is in use a t a time.
132 kV Switchgear
The 132 k V switchgear is o f the Metro
politan-Vickers impulse outdoor type, air- operated at 160/200 lbs. per sq. in .; its rupturing capacity is again 2 000 MVA, with three ¡separate single-pole breaks.
The 6 k V switchgear, Of the B .T -H . QF and MF types, has a rupturing capacity of 75 MVA and 250 MVA respectively. The 400 V switchgear is also of B .T-H . manu
facture, type AJ, air-break 600 A.
Star points of the 132 k V windings of each o f the 45 M VA inter-connector trans-' formers, and of. the 75 M VA generator step-up transformer are earthed solidly while the star points on the 66 kV windings
are earthed through tw o earthing resis
tances of th e.m etal grid type, each rated at 1 000 A for 15 secs. Star points on the alternators are earthed through single
phase. potential transformers, while .the 6 kV station transformers are earthed through potential transformers as for the alternators; the unit transformers, b y means of fuses having potential transformers con
nected across them. All 400 V systems axe earthed in each case through a fuse in the star point o f the transformer feeding the system ; in parallel with the fuse is a spark gap. Voltage regulation is b y B .T-H .
