In a first in state, Madhya Pradesh Power Transmission Company Limited (MPPTCL) has used a hybrid switchgear module as part of expansion of its transmission system in Indore.
Officials said that the system had been developed and implemented by a team of engineers to meet requirements of the company. We have used a hybrid switchgear module system in a transformer of 50 MVA capacity at the 220kV substation of Bicholi Mardana area in Indore. It is for the first time when a hybrid switchgear module system has been used by MPPTCL in the state as part of the ongoing expansion of our transmission Network, MPPTCL managing director (engineering) Sunil Tiwari said.
He said that they had replaced conventional system with a hybrid switchgear module and underground insulated cabling setup for 33kV voltage supply to the 220kV substation for distribution. The arrangement has been put in place due to an increase in power demand. But space constraints posed a difficulty in installation of a conventional switchgear system. It prompted us to develop a hybrid switchgear module system at an estimated cost of Rs 1.5 crore. The system uses less than 1/3rd of the area required by the conventional system, said Tiwari.
