    Tips: Difference between signal relay and power relay

    Signal relay is usually used for monitoring and protection. It is widely used in the secondary protection circuit of distribution high voltage cabinet. For example, If the transformer oil temperature is over 85 degrees and A normally open contact is closed on the temperature monitor indicator, making the contact string in signal relay coil back to the road, so there are signals leads to relay coil absorption and action and high voltage switch is off at the same time to remove the station transformer load, so as to protect the transformer. However, there are many kinds of signal relays, some of which are directly buzzing or flashing as alarm signals.
    Power relay is a device that can produce step in one or more electrical output circuits when the input (or excitation) satisfies some specified conditions. It can be used in the neutral point directly grounded system as the direction element of zero sequence current protection.
