 Executive Summary
Introduction
Project: INS VALSURA
Electrical Contractor: SIEMENS INDIA LTD, MUMBAI
ElectricalDistribution System 6.6/0.415 kV Distribution system
Power System Data
Max Source Fault level Fault Currents calculated based on alternator data.
(assumed)
Tools used: ETAP VERSION 18.1
Protection Coordination

The short circuit currents at various busbars are calculated based on the above
assumptions. Calculated Short circuit currents are tabulated in the report and
also shown in the SLD.
Selectivity of relays and circuit breakers were worked out based on the cable size
and flow of short circuit currents.
Time current characterstic curves are generated for every path and verified .
Conclusion
Settings for each device,short circuit currents at every busbars,detailed
calculations for the settings are given in the following pages. No deviation is
observed and the interuupting capacities of the devices are above the calculated
short circuit currents .
