Because of presence of backup relays, no interruption has to take place for any equipment or circuit. During this time back up protection scheme takes care of the protection of the system. As the back relaying is second line of protection it must be slow in action than main relay so that it can only be operated when the main relaying scheme of the system/equipment fails.

Low burden. Protection: Requires higher accuracy at higher currents (Class 5P10 or 10P10). Should operate correctly under fault conditions. ŌC/EF used for overcurrent and earth fault protection REFprotection Very sensitive to current mismatch. Requires matched CTs with wide dynamic range (Class PS or 5P20). Used on both sides of a transformer. For an 11kV feeder, typically 3 CT cores per phase are required: • Core 1 – Metering • Core 2 – Protection (OC/EF) • Core 3 – REF The OEM of CT must take the data like lead resistance, relay burden, and system fault level from the MES before designing PS class CT. Core 1 & 2: Protection Cores These cores are designed to operate accurately during fault conditions and saturate quickly above the fault level to protect connected relays. Accuracy Class: Typically 5P or 10P (e.g., 5P10, meaning 5% error at the accuracy limit factor of 10).Burden: Typically 10 VA, 15 VA, or higher, depending on the connected relay\"s requirements and cable length.Accuracy Limit Factor (ALF): e.g., 10 or 15. Special Purpose (PS) Class: For high-impedance or differential protection, a PS class is used, specified by: Knee Point Voltage Not less than 700 V (depends on ratio and burden).Excitation Current Specified at a certain percentage of the knee point voltage. Secondary Winding Resistance Measured and considered for relay settings. Saturation Factor: Minimum of 10 for standard protection cores.Core 3: Metering Core This core is designed for high accuracy under normal operating conditions. It has a low Instrument Security Factor (ISF) to protect the connected meters from damage during high fault currents. Accuracy Class: Typically 0.2S, 0.5, or 0.5S.Burden: Typically 5 VA or 10 VA.Instrument Security Factor (ISF): Less than 5 at the lowest ratio to protect meters. |
