The additional wiring in the R.A.F. Muharraq Camp was carried out by the R.A.F. The
R.A.F. also wired during 1363 the British Overseas Airways Corporation Rest House ( third floor)
for 48 light points and 15 fan points. The Electricity Department carried out the wiring of Govern­
ment and certain other premises as follows:—
1. New Food Control Office.
2. Government Hospital—additional wiring.
3. The Agency and A.P.A.'s house—additional wiring.
4. Muharraq Girls' School—additional wiring.
5. The Adviseratc—additional wiring.
6. The State Engineer’s Office—additional wiring.
7. Ebrahim bin Butti’s Workshop in Muharraq—a three phase supply for lathe, etc.

Also other minor additions in various other premises.
Main Extensions.—Two main extensions were carried out during the year 1363, as follows:—
(1) A High-tension overhead line to the Tank Installation of the R.A.F. on Muharraq Island
with a 30 KVA transformer—Material provided by the R.A.F.
(2) A High-tension line to the new Transmitting Station of the Royal Navy with a 50 KVA
transformer—Material provided by the Royal Navy.

Air Conditioning.—About 45 A.C. units were in operation in 1363. At the end of 1363 the
R.A.F. had a connected load of 122 K.W. for air conditioning only on their Muharraq Camp. The
load would have increased but for the difficulty of obtaining A.C. plant.

Continuity of Supply.—The Electricity Undertaking has been in operation since May, 1930,
and during the months of Dilquada and Dilhaja, 1363 (November-Dccember, 1944) when weather con­
ditions were bad owing to heavy rain and winds there were 166 power distribution failures, all external.
It is apparent that inefficient inspection and maintenance was an additional contributory factor to
these failures. The general condition of the power distribution standards is very bad owing to
excessive corrosion and a large percentage are badly holed. Several have been found to have become
unsafe and a few have been replaced, but owing to the non-availability of a sufficient quantity of
spares it has not been possible to undertake a general replacement.
Temporary repairs arc being made by encasing the lower extremities of the standards in a
concrete column when the damage is limited to such parts. In other cases steel collar clamps are
bolted in position to reinforce the damaged area. The early replacement of a large percentage of the
standards is an essential requirement, particularly those in close proximity to the sea in Manamah and
along the causeway to the Shaikh Hamad Bridge.
Reduction of the diameter of the feeders owing to corrosion has been checked and found to be
of an average order of 10 per cent. In view of the fact that no major replacements have been made
since the original installation 14 years ago this is considered to be a normal condition under the pre­
vailing climatic conditions. Cross arm brackets and other ferrous clamps and fittings however
require constant replacement as the result of excessive corrosion and insufficient protective covering.
This has been inevitable owing to the short supplies of suitable paint during the past five years.

No. 1 Generating Set of 100 K.W. capacity was out of service for a period of seveo weeks during
the months of November 1944 and January 1945 owing to a defective air compressor for which no
spares were available. Eventually, repairs requiring the use of machine tools were kindly carried
out by the Bahrain Petroleum Company.
Owing to this failure the R.A.F. were required to run their own standby generators and the
disconnection of one or two section feeders had to be arranged daily in order that the usual mainte­
nance of the other two generating sets could be carried out.
