High Power Laboratory

To meet the growing needs of short circuit testing of switchgear and power transformers, the high power laboratory was established in CPRI, Bangalore, in 1991. The laboratory was planned with total installed capacity of 7500 MVA, which is to be achieved in three stages. In the fi rst stage, 2500 MVA direct test facility with parallel current injection synthetic test circuit was installed. The technical consultancy for the laboratory was provided by EDF High Power Laboratory, Les Renardiers, France. The vital equipments of the laboratory, viz, short circuit generator, short circuit testing transformers and the master circuit breakers and make switches, are specially designed with essential technical characteristics required for short circuit testing of switchgear, power transformer and other electrical power equipments. The laboratory is having the most modern measuring, control and protection equipment. The short circuit and switching tests conducted in the laboratory are strictly in accordance with IS, IEC, ANSI standards. The short circuit generator has been converted into motorless system with state-of-art technology electronic controllers, which ensure trouble-free testing service to customers from our country and abroad. The two decades of service rendered by CPRI High Power Laboratory has resulted in quality-rich, reliable switchgear and power equipment for the utilities and end users. The laboratory is providing continual service to nation building activities in the fi eld of power sector.
