What does KCO represent in relay protection

The K factor (or zero-sequence compensation factor) adjusts the measured impedance for the phase-to-ground fault loop by accounting for the contribution of zero-sequence currents. This compensation is critical because zero-sequence current introduces an offset in the fault impedance. The protection and control devices in electrical equipment can be referred to by numbers, with appropriate suffix letters when necessary, according to the functions they perform. These numbers are based on a system that is adopted by a standard for automatic switchgear by Institute of Electrical. The following Terms are used in protective relaying: 1. Fault Clearing Time 5. Drop Out or Reset value 8. Sealing Relay or holding Relay 10. Time-graded protection is implemented using overcurrent relays with either definite time characteristic or inverse time characteristic.
