A current transformer (CT) is a type of electrical device used to convert high voltage currents into a low-voltage current that can be monitored by a standard ammeter. It is an important part of an el...
A shunt is a resistor that has low, known resistance, and is placed in parallel with the current-carrying conductor. Energy shunts are used in a wide variety of applications, including current measure...
A 80a latching relay is a switch which can be used to control high current circuits using a low power signal. These relays have the added benefit of positional'memory' which means they will remain in ...
When designing an energy meter shunt, it is necessary to take several factors into consideration. First, the shunt must be properly sized to ensure that it can handle the current running through it wi...
A relay is an electrical device that switches current between two or more circuits. It consists of a small metal strip that, in essence, revolves between two terminals. The switch mechanism has a coil...
In many cases, the current measurement system in a smart energy meter requires shunt resistors to function. These shunts are used to bypass the direct current passing through the meter to extend the r...
A power shunt is a device used to redirect current through a different path in an electrical circuit. The shunt provides a low-resistance connection between two points in the circuit. A shunt is often...
A current transformer (CT) is a device that steps down a high current in an alternating current circuit to a lower, safer level. CTs are commonly used in metering applications and protection devices, ...
A three phase meter current transformer is used to convert a primary current to a secondary current. They can be found in various shapes and sizes, and have a wide range of amperage ratings. These are...
In the energy meter industry, many meters use shunts as current sensors. This is mostly because they cost less than other types of current sensors and provide magnetic immunity that makes them a good ...
When it comes to energy bills, one of the key components is your energy meter. It shows how much electricity and gas you're using each month and allows you to top up by text, app or online at any time...
A magnetic latching relay is a device that can toggle one circuit on and off or switch power between two circuits. It works by exposing a strip of magnetized wire that is placed between a series of co...
