Abstract

A cable for monitoring current and voltage includes a plug, a socket, first and second conductors extending from the plug to the socket, a current and voltage monitoring module, a transceiver, and a housing. The current and voltage monitoring module is coupled to the first and second conductors, and is configured to measure current and voltage usage levels of the conductors. The transceiver is coupled to the current and voltage monitoring module and is configured to receive data related to the current and voltage levels and transmit the data related to the current and voltage levels. The housing is configured to house the current and voltage monitoring module, the transceiver and one of the socket and the plug.

Claims

1. A cable, comprising:

a plug at a first end of the cable;

a socket at a second end of the cable;

first and second conductors extending from the plug to the socket;

a current and voltage monitoring module coupled to the first and the second conductors and configured to measure current and voltage levels of the conductors;

a transceiver coupled to the current and voltage monitoring module, configured to receive data related to the current and voltage levels and transmit the data related to the current and voltage levels; and

a housing configured to house the current and voltage monitoring module, the transceiver, and one of the socket and the plug.

2. The cable of claim 1, wherein the transceiver is configured to use a wireless low power communication protocol to transmit the data related to the current and voltage levels.

3. The cable of claim 2, wherein the wireless low power communication protocol is IEEE standard 802.15.4.

4. The cable of claim 1, wherein the current and voltage monitoring module is configured to operate in one of a sleep mode and a wake mode.

5. The cable of claim 1, further comprising a capacitor configured to store operating power for at least one of the current and voltage monitoring module and the transceiver.

6. The cable of claim 5, wherein the current and voltage monitoring module is configured to charge the capacitor in a sleep mode of operation.

7. The cable of claim 1, wherein the socket is a IEC C13 standard socket.

8. The cable of claim 1, wherein the plug is a IEC C14 standard plug.

9. The cable of claim 1, wherein the cable is a three phase cable.
