A shunt is an electrical device used in energy meters to measure the flow of electricity. It provides a low-resistance path for a portion of current and creates a secondary circuit that can be used to measure the voltage drop across the shunt. There are a number of different types of shunts that can be used in energy meters. These include series shunt, split shunt and current transformer shunt.
Shunts are typically used for measuring current in an electric circuit, although they can be used for other applications. They work much like a T valve in that they restrict a portion of the electricity from flowing through the main wire, allowing it to be diverted to a different path. This can make the meter more sensitive as it only has to measure a small amount of current that would normally be going through the main wire.
There are many different kinds of shunts, and the ones that you need for your particular application will depend on what you are trying to use it for. Here are some of the most common types:
SS/CWS shunts: These shunts use a thin layer of copper to provide a low-resistance connection between two points in an electric circuit. This makes them an ideal choice for measuring current, because they can be very accurate. This can be done by connecting a meter to the shunt and measuring the voltage drop across it.
PML has a wide range of shunts for energy meters available. These shunts can be made of a variety of different materials and are designed to suit specific applications. They are also available in a range of different shapes and sizes to match the needs of their application.
DTSY666 Three phase four-wire electricity prepaid meter: This shunt can realize the functions of energy metering, maximum load limitation and so on. It can pre-sell electricity and also set a power off threshold, which can automatically power off when the electricity is no longer needed.
The meter is also able to send back usage data, which can be used for settlement, statistics and management purposes. It can be connected to an in-home display and has the ability to top up by text, app, phone or online at any time.
A smart pay-as-you-go meter: These meters allow you to monitor how much electricity and gas you are using and manage your bills at the same time. They can also be topped up by text, app, phone or online and can show you how much money is left on your account at any time.
Shunts are usually made from a copper-based alloy. This allows them to withstand the temperature that they will be exposed to in a utility company's buildings. They are rated to withstand temperatures between 40deg and 60degC.
Ofgem warns that the pace at which suppliers are shunning vulnerable customers onto prepayment meters is "unacceptable". In fact, it has been revealed that as many as 600,000 households were forced to switch to a prepayment meter in 2022 - an increase from 380,000 the previous year.
