What is Electrical Metrology and What Does It Involve?

This branch of industry covers both control measurements of electrical quantities in circuits and the measurement of other quantities where electrical energy is used.

What Are Medium Voltage Current Transformers and Converters? How Do They Work?

These are devices that allow measuring large current values with meters that have smaller measurement ranges. In power engineering, it is often necessary to know the values of supply voltages and currents flowing in powered circuits, which is why medium voltage current transformers can be useful and enable the measurement of large currents and voltages using meters with smaller measurement ranges. Thanks to galvanic isolation of the measurement circuit from the main high voltage path provided by the transformers (often also called measurement transformers), the entire process is carried out safely.

In the case of control measurements of electrical quantities in circuits, meters for quantities such as voltage, current, resistance, or power are directly connected to the circuit. For measuring other quantities, such as temperature or rotational speed, the meter must be equipped with a converter so that the measured quantity can be presented in appropriate units.

We distinguish between Medium Voltage Current and Voltage Transformers – based on the type of physical quantity being transformed.

Medium voltage current transformers are divided into: universal current transformers for rails and wire/wire; with an opening core; with primary winding; three-phase; for protection; for energy settlement; with a converter.

Current Transformer – Applications.

- For proportionally changing large current values to lower ones.
- To extend the measuring range of ammeters.
- Measurements with meters with small measurement ranges.
- Galvanic separation of measuring devices from the controlled circuit.
- Allows placing measuring devices at a large distance from the controlled circuit.

Medium Voltage Current Transformer – Application and Benefits

Medium voltage current transformers are essential devices in power systems. They enable the measurement of large current values using meters with smaller measurement ranges. Their basic applications include:

-Proportional change of large current values to lower ones – Current transformers allow transforming high currents into lower, safe values that can be precisely measured by standard meters.

-Extending the measuring range of ammeters – Current transformers allow precise measurement of currents that exceed the safe range for direct measurement, protecting the measuring equipment from damage.

-Galvanic separation of devices from the controlled circuit – providing electrical isolation between the high-voltage circuit and measuring devices, ensuring operational safety.

-Safe placement of meters: allowing measuring devices to be placed at a safe distance from active circuits, which is essential in large industrial installations.
