IMPORTANT PENDING WORKS
4 Nos BD and 4 Nos UD 66 KV Energy meters with ratio 800/1A are required.
28 Nos cooling fans for 100 MVA Power Transformers T-4 & T-5 are required because existing cooling fans have been repaired so many times.
8 Nos cooling fans for 10/12.5 MVA Power Transformer T-3 are required because existing cooling fans have been repaired so many times.
Some 220 kV and 66 kV CTs need replacement due to the absence of metering cores / high tan delta value / low fault level rating of the CTs.
A CDB Double Bus Bar of 14 Ckt. with bus coupler is required because existing one is very old and switches are very defective.
HT side bushing of Y phase of Power Transformer T-4 needs replacement due to high Tan Delta value.
LV side bushings of R & B phases of Power Transformer T-5 need replacement due to high Tan Delta values.
Some sections of steel net fencing of sub station are damaged which need replacement.
