Failure of protection equipment leads to major breakdowns, which will cause huge loss in production as well as damage the system equipment. AMC is just like a periodical health check up to avoid breakdowns and production loss for industries. Such breakdowns can be avoided only through proper maintenance of protective relays and protection schemes.
Our AMC teams are systematic and reliable, who concentrate on maintenance and testing of all electrical equipment and protection schemes at regular intervals every year to ensure protection healthiness.
Immediate response to emergency calls, on - line guidance, trouble shooting and gap analysis – these are the special features of our AMC operations.
We execute maintenance testing of electrical components like CTs, PTs, Lightning Arrestors, Transformers, Circuit Breakers, Isolators & Earth Pits. We do testing of protection relays and calibration of meters.
Our AMC teams are committed to provide quality services with specific standards within the stipulated time period and also reminds the customers at the right time to do AMC, even if the customer fails to forget.
We provide standard test reports for all electrical components and various electrical schemes by soft copy as well as hard copies as requested by the customers which may useful during inspection by Boards / Authorities and also for future reference and records.
We are concentrating more on substations, power plants and process industries like Steel, Sugar, Cement, Refinery, Chemical, and Textiles etc. in addition we also extend our AMC services to multistoried building such as Commercial Blocks & Tec park etc.
