Consultancy Projects

  • Consultancy through Field Testing

Diagnostic laboratory is equipped with test facilities for undertaking condition monitoring/diagnostic tests on HV Power Equipment in order to assess the state and condition of their insulation systems. Diagnostics test facilities are extensively used by State Electricity Boards, Thermal Power Stations, Nuclear Power Stations, Hydro Power Stations, Petro Chemical Plants, Process Industries and the like.

  • Involved in Renovation and Modernization (R&M) & Residual Life Assessment (RLA) Studies.

Majority of the generating sets operating in our country are about 35-40 years old and have already come to the end of their notional design life. In recent times, with the ever growing demand for power, high cost of new equipment and paucity of funds there is an increasing trend to upgrade and extend the life of older generating sets. It has been recognized that with the advent of new technologies there is a scope for upgrading of generating capacity of the generators. In the light of this, knowledge of integrity of these machines and their remaining service life would be of great interest. In this, endeavor; there is a strong incentive for condition assessment of various components of these machines. Over the years many diagnostic tests have been suggested for condition monitoring of different components of the machines. The data obtained from these tests provide much needed information regarding present state and condition of the components.

  • Failure Investigation of EHV/HV Power Equipment.

To understand the root cause of failure of any power plant equipment, failure investigation is carried out. Diagnostic laboratory is equipped with facilities and expertise for failure investigation of failure of HV equipment line generators, HT Motors, Power Cable etc.
