6 INSPECTION AND TESTING
6.1
Engine testing:
The
engine will be run-in at the test bench at worshop before delivery. Subsequent
test of 3.5 hours will then be carried out as per following schedule. .
1/2 Hour at 50
% COP .
1/2 Hour at 75
% COP .
2 Hours at
100 % COP .
1/2 Hour at 110 % COP For
these tests, engine will be coupled to a hydraulic dynamometer and run on DO as
fuel. An allowance of 4.5 gm/hp/hr
on SFC will be considered for the first 500 hrs of engine operation. 6.2 Alternator testing: Following
Routine tests, as per Annexure will be conducted on the alternator at Workshop. 6.2.1
For generator armature, generator field, exciter armature and exciter
field. .
Measurement of resistance. .
Measurement of insulation resistance. .
High voltage test. 6.2.2
Phase sequence test and voltage balance check. 6.2.3
Open circuit characteristics With
generator line voltage recorded against exciter field current. 6.2.4
Short circuit characteristics With
generator line current recorded against exciter field current. 6.2.5
Voltage regulation test Conducted
with AVR in the circuit with reactive loads up to 800 KVA. 6.2.6
Control panel test Standard
routine tests as per the relevant ISO standard. 6.2.7
DG set test. After
D.G.Set installation, online checking of all the auxiliary functioning
& fine tuning of fluid circuit
pressure/temperature setting is carried out on load.
This exercise requires one week (Approx.) for completion.
During this time, load for D.G.Set shall be made available by customer as
& when required. After completion of above D.G.Set shall undergo the
load tests at site, for 4 hours. For this purpose the load is to be made
available by the purchaser. During the tests, all the important parameters, as
per our standard procedure will be checked
& recorded. |
