Calibration and testing of Power transformers:- The scope of work includes calibration and testing of Bucholz relays, temperature monitors/gauges, all routine tests as per relevent IS for transformers such as measurement of IR value,PI values,tan-delta test , furan test, oil BDV test etc. and Dissolved Gas Analysis test(DGA) of one no.110/11KV,23 MVA transformer and two nos 15MVA transformers at site. The tan-delta test of winding shall be carried out using proper instruments by qualified and experienced persons. Oil BDV and DGA test shall be carried out at fully equipped and NABL approved laboratory. Original along with a copy of test certificates duly signed by authorized agencies shall be furnished along with final bill.

Testing of 110 kV CT's and PT's:- The scope of work includes test for health assessment of CT's and PT's used in FACT-CD 110 kV yard such as measurement of IR value and tan-delta measurement etc.
