The security device (substation insulation type) is connected to the remote monitoring control device of the substation in the carrier transmission mode, and the connection line access point connected to the blocking device, etc., when the power is transformed

When an accident causes a rise in geodetic potential in the area and induces abnormal voltages such as lightning surges on the connection line, it can protect the human body from injury and prevent the insulation of equipment and lines Destroy.
