Bias Differential Relay. The bias setting in differential protection ensures that the relay can handle slight current imbalances caused by external faults without tripping unnecessarily. The general characteristic of a restrained differential relay is to trip on the basis of the differential current exceeding a set percentage of phase current. The only difference between them is the restraining coil. Figure (6.2) shows the single line diagram of the percentage biased differential relay scheme for the transformer. Generally differential protection relay means the relay operates when the phasor difference. Differential protection is typically employed for electrical power transformers rated above 5mva. It is the advanced form of differential protection relay. The biased beam relay (also called percentage differential relay) is designed to respond to the differential current in terms of. Percentage differential relay or biased differential protection: The percentage differential relay is defined as the relay that operates on the phase difference of two or more similar electrical quantities exceeds a predetermined amount. Bias is adjustable by tappings on the restraining winding and setting by spring.
