We offer numerical under over voltage protection relay.
Mvt 181 is a numerical true rms single pole relay consists of two elements. Each element can be selected for under voltage function or over voltage function or switched off. The characteristics setting, voltage setting and time multiplier setting are independently settable for each element and the voltage setting is in terms of voltage. Hence this relay can be used as a two stage under voltage or two stage over voltage protection.
multiple characteristics:
there are four operating characteristics for over voltage function and two operating characteristics for under voltage function
