Phase comparison device for verifying phase consistency for medium voltage switchgear, has cable arranged at ends of set of connection terminals complementary to another set of connection terminals

摘要

The device (10) has a housing (12), and a connection unit (16) for obtaining a signal representative of phase voltage. Another connection unit obtains signal representative of another phase voltage. A comparison unit (14) compares signals representative of the phase voltages. Each of the connection units includes two different types of connection terminals (22, 22'). A cable (24) is arranged at ends of another set of connection terminals (26, 26') complementary to the connection terminals of the connection units.
