Why do I need a current transformer for a meter

A current transformer for a meter is a device that reduces the primary voltage. The amount of electricity consumption in residential, office and industrial facilities depends on the power of the electrical equipment used. To control its consumption, a meter is installed, the readings of which are taken into account when paying.

The standard model has a winding designed for a current of 5 amperes. This is enough for small warehouses and even industrial premises, ordinary apartments and houses. But there may be a situation when the load passing through the measuring device significantly exceeds this indicator. This happens if high-power electrical equipment is used, or the number of consuming devices is much higher than the calculated one.

In this case, there is a risk of damage to the meter at peak loads of more than 5A. To solve the problem, special current transformers, otherwise called measuring transformers, are used. An electric meter in circuits with a current consumption of more than the norm is connected through these devices to the load, carrying out correct accounting of electricity consumption.

How are current transformers arranged?

The simplest transformer is made in the form of a steel core with primary and secondary windings. For the first winding, a large-section wire is used, the secondary one is connected to the terminals of the meter. The number of turns is selected in such a way as to obtain a standard indicator of 5A.

A current transformer with a detachable core is very often used – it is very convenient to install it on the bus without cutting the cable. The body of such a device is also detachable and consists of two parts, with a central hole.

You can buy a current transformer for a meter to account for electricity consumption in a standard 220V or 380V power grid. Another option is to select transforming devices for electric lines with other voltage parameters, including those that use constant voltage. It is clear that a DC transformer, which you can buy in the Schetchik online store.uz, is called so conditionally. It is a device that converts voltage into a high-frequency pulse charge, transforms it and rectifies it, giving acceptable values to the devices.

Transformers can be used not only with standard electric meters, but also with any other measuring devices, including such:

• power meters;
• switch devices (ammeter, voltmeter);
• current parameter meters;
• power regulators;
• electrical energy quality analyzers;
• active power filters.

It is worth noting that the price of current transformers is relatively low, which allows you to easily choose the most suitable option for specific operating conditions.
