Meter locking system |
摘要 |
A remotely controlled locking device is provided for preventing unauthorized withdrawal of watt-hour meters from their sockets. The locking device is typically located beneath the base of the meter in the socket, and both the meter and socket can be of standard design. The device may be associated with apparatus to indicate withdrawal of the meter and to count interruptions of power to the meter, thereby providing further security against tampering.
