General

1.1

The purpose of this document is to provide project design calculation for sizing of the 6.6kV capacitor banks for M/S UTCL, Katni Unit.

1.2

This document describes the 6.6kV capacitor sizing calculation as per the various 6.6kV motor data sheets and sizing the capacitor for the 7.2kV system (considering 10% over voltage), sizing the series reactor for the required 7.2kV capacitor bank system
