General

There is only 1 no. 5MVA, 33kV Power transformer installed in the bay. The station auxiliary supply is taken from 250 kVA, 11kV/ transformer which is tapped from the 11kV bus, in the station.

In addition to RPG 1 and RPG 2.2 No: 11kV feeders in the 11kV bus. One is 11kV town feeder from this station for feeding the nearby Vadasserikkara, Perunad area. Hence 11kV town and 11kV Perunad breaker can be put in alternate use. Similarly two 11kV AB switches are installed in the substation compound for the selection of 11kV TOWN/PERUNAD supply. The maintenance of the AB's and its DP's are carried out by Electrical section Vadasserikkara.

The custodian of feeders such as RPG-1, RPG-2, 33kV PTPE etc. are Electrical section Vadasserikkara.

The 11kV Town/Perunad feeder can be extended to 11kV Vadasserikkara feeder from 110kV substation, Ranni. Usually this done by the field staff of Electrical section, Vadasserikkara by closing the 11kV Delta AB. During the failure of 33kV PTPE feeder, the SHEP R-PND is connected to the grid through 11kV Vadasserikkara feeder, the load in the Vadasserikkara feeder is regulated by Electrical section Vadasserikkara for easy synchronization.^[1]

Introduction

The substation is fed from 110 kV substation Pathanamthitta through one 33kV feeder (33kV PTPE feeder). The two 11kV feeder RPG 1.RPG-2 are fed from the 2x2MW, small Hydro Electric Project at Ranni Perunad works under the tail race of 12MW, Maniyar Hydro Electric Project by carborandum universal ltd. The RPG-1 and RPG-2 are mainly used for the power evacuation from R-PND SHEP while on generation and also used for taking auxiliary supply from R-PND 33kV substation.^[2]
