10.6.3 Protection by current monitoring
relays
The current monitoring relay constantly
measures the current in an electrical wire. The
current is indirectly reflecting the torque on the
electric motor. If the measured value exceeds the
adjusted threshold value the relay sends a signal
to a main switch that cuts of the power to the
electric motor.
When using a current monitoring relays together
with a VFD attention must be on choosing a VFD
compatible relay.
