Phase Voltage Unbalance Monitor |
3 Phase
Voltage Unbalance Monitor from Time Mark
Description
The
Model 200 3-Phase Voltage Unbalance Monitor is designed
to continuously monitor a three-phase line for unbalanced
voltage conditions.
This device will only energize the relay if an unbalance exists.
Zero volts on all three phases is considered a balanced condition.
This allows the Model 200 to be used with shunt breakers,
so that the breaker can shut off the main power without tripping
the monitor.
The solid-state sensing circuit drives an internal electromechanical
relay. Indicator lights on the monitor show when the voltage
balance is within an acceptable range; when an unbalance exists;
and when the relay is actually tripped.
When an acceptable voltage balance is reapplied, the Model
200 will automatically reset the relay.
