摘要: A monitoring circuit connected between a motor and a motor reversing switch is shown and described. The monitoring circuit has a current transformer connected to the power line to be measured, two secondary variable monitoring circuits for measuring the actual current value of the motor, and actual value analyzers for controlling the monitoring circuits. One of the secondary variable monitoring circuits is switched on while the other is switched off.
