How to build your Energy Load manager

A detailed instructions of how to build an Energy Load manager from Open Electronics: When the instantaneous power consumption exceeds the set values, it selectively disconnects the users, in order to prevent the electric meter to cut the power to disconnect. The management of the electricity users at home, intended as the possibility to define […]

Energy Meter module to analyze the electrical grid parameters and consumption

Boris Landoni from Open Electronics writes about a new open source energy meter project: In the first installment, you had the opportunity of learning about our energy meter, and of learning about its details, with special attention the technical ones. Our energy meter is based on the coupling – by means of two measuring transformers – […]

App note: Atmel AVR465: Single-phase power/energy meter with tamper detection

A good read from Atmel on their 8-bit microcontroller single-phase energy meter design. Link here (PDF) This application note describes a single-phase power/energy meter with tamper logic. The design measures active power, voltage, and current in a single-phase distribution environment. It differs from ordinary single-phase meters in that it uses two current transducers to measure […]

App note: Application of leaded resistors in energy meters

App note from Vishay about energy meter circuits and the use of leaded resistors on them. Link here (PDF) An electric meter or energy meter is a device that measures the amount of electrical energy supplied to a residence or business. It is also known as (k)Wh meter. The main unit of measurement in the […]
