Multifunction relays have combinations of device numbers. A 27/59 device, for example, is a combination under/over voltage relay. Letters can be added to clarify application (87T for transformer differential, 59G for ground overvoltage).
16V or 32V Over-Voltage Protection Relay (OVP) with Low and Over-Voltage Warning For Type A or Type B 14V Alternator Systems.
This simple electronics circuit uses timers in place of comparator as in the above case as a control mechanism. provide over current protection, directional over current protection (for selectivity in case of multiple parallel lines), under/over voltage protection, breaker failure protection (in case the breaker fails to trip even after receiving the trip command), etc [5]. Figure 4 shows the connection of a distance relay for line protection. ` ` Line over-voltage protection relay.

The Over voltage setting is usually 110 to 130 percent of the normal operating voltage depending on the system requirement. If the voltage rises above than this level for the set amount of time then the tripping command issued by the relay and hence the system is isolated.
Multifunction relays have combinations of device numbers. A 27/59 device, for example, is a combination under/over voltage relay. Suffixes and prefixes. A suffix letter or number may be used with the device number; for example, suffix N is used if the device is connected to a Neutral wire (example: 59N in a relay is used for protection against Neutral Displacement); and suffixes X,Y,Z are used for auxiliary devices. REU611 is designed for overvoltage and undervoltage protection, sequence protection, residual overvoltage and additional two-stage frequency protection of large-size power stations or small power units. The voltage protection relay is used for a wide variety of applications, including busbar, power transformer, motor and capacitor bank applications. The relay of over voltage and under voltage circuit can be used for protection of transformers, motors, and generators as the relay is generally used as a three-phase relay.
