  • Principle of High Voltage Motor Relay Protection

    Principle of High Voltage Motor Relay Protection

    Electromagnetic Relays: Working on the principle of electromagnetic induction, these relays are typically used for phase failure and under/over voltage conditions. They act quickly to isolate the motor and protect it. High Voltage Induction Motors: These motors are preferred for high power applications (above 250HP) due to their reduced operating. Motor Protection relays are used to protect the higher HP high voltage induction motor. Once the temperature crosses a certain threshold, it trips the circuit. It is suitable for critical equipment like servo and high-voltage.
