Circuit Branch Measuring System

[0012]The technical advantage of the invention is to us a single current measurement and data transmitting device to securely measure up to several circuit breakers using current sensor modules, which are mechanically and electrically connected to the current measurement and data transmitting device.

[0013]In a first aspect of the present invention a circuit branch measurement device is provided. The circuit branch measurement device comprises at least one current measurement and data transmitting device, which further comprises a microprocessor to obtain and process measurement signals, a communication driver to transmit collective data to an external device, an identification microchip for associating identification numbers to current sensors, an input/output interface for external power supply and data transmission, and at least one connector for mechanically connecting to a current sensor. The circuit branch measurement device also comprises at least one current sensor module, which further comprises a current sensor to measure a current by a conductor, and a connector for electrically connecting to an external device for power supply and data transmission. The circuit branch measurement device is characterised in that the current measurement and data transmitting device is mechanically coupled and electrically connected to the at least one current sensor module for detecting a current by at least one circuit branch in an electrical distribution panel. Also, the current measurement and data transmitting device aggregates and consolidates measurements from at least one of the current sensor modules to be transmitted from the system to an external device.

The problem with this system is the size and limited communication abilities,

This is especially disadvantageous as distribution panels are typically dense with separate conductors related to each circuit breaker, neutral and ground connections of each circuit branch, including conductors for the Main breaker and other protection devices associated to an electrical installation.

As circuit breakers by an installation in distribution cabinets are typically numerous and positioned in line and relatively close to one another this arrangement is also costly and impractical by installation.

This is especially disadvantageous due to dimensional restrains in
