GENERATOR FOR BATTERY CHARGER

1. Generator for Battery charger commissioning should be more then 220KVA

2. Normally generators are Thyristor control and voltage will regulate according with load .

3. Battery chargers contain RLC circuit and it will rise the generator voltage abnormal value.

4. Connect some external lighting loads rather then battery charger to avoid this abnormal condition.

POWER TRANSFORMER ERECTION

115kv 67MVA Transformer

1.Erection takes total 8 days with 15 man power
2.Vaccuming of main tank take 3 days upto  -0.5tar
3.Oil circulation 3 days
4.Oil Filling and setteling 1 days

=8+3+3+1=15 days / Transformer
