Abstract: A circuit branch measurement system and device are provided for detecting electrical current by circuit branches in an electrical distribution panel. The circuit branch measurement device consist of a current measurement and data transmitting device which is electrically and mechanically connected current sensor modules. The system comprises an identification device to associate each attached current sensor module with a unique identification number and a communication driver to transmit the collective data from the system to a monitoring device.

Abstract: A current measuring device for circuit breakers with an improved electronic circuit arrangement by way of arrangement and method for displaying electrical line current by a circuit breaker wherein measurements are made by at least one current transformer. Indications of the magnitude of electrical current are displayed by at least one LED and by the intensity of illumination by each LED. The current measuring device is placed onto a circuit breaker wherein at least one LED of the improved circuit is made accessible by sight at the front face of the current measuring device attached to the circuit breaker. A current transformer is located inside the current measuring device attached to the circuit breaker for measuring the current flowing through the conductor applied to the circuit breaker.

Abstract: A system of using electrical detection and reporting devices in conjunction with existing electrical protection devices by an electrical installation, wherein the said measuring devices are used by existing circuit breakers and terminal blocks to measure and identify electrical load and residual current in said electrical installation. The system measures residual current, current and voltage and displays information on said measurements by LEDs wherein the system consists of using a dedicated CPU for collecting, analysing and transmitting the data of the system through wireless and Ethernet/internet connections.

Abstract: An electricity metering arrangement comprises a circuit breaker with an installed light indicating electricity meter displayed on the front of the unit. The electricity meter comprises a light indicating unit which may be a LED light or LCD display. The circuit breaker based on the invention is combined with a circuit breaker housing (1), a circuit breaker (2) and a built-in light indicating electricity meter (3). It is controlled with a switch (4) and has a fastening unit (5) on the back of the housing. Connections are made to the circuit breaker with screws on top (6) and under (7) the housing. Measurements are displayed on front of the circuit breaker by a light indicator with a scale (8) indicating the electricity load status.
