For current transformers, the rated current of the primary winding is specified, while for voltage transformers, the maximum voltage of the primary winding is defined. Resistor networks are connected to the secondary windings within the device, and the resulting voltage signals are supplied for further electronic processing. The values of the signals in the secondary winding depend on the primary signals and the resistor network (e.g. according to the diagram below).

Insulation test PRI–SEC: 4kV
Transformers are manufactured in open-type and resin-filled versions.

The post BTI first appeared on Breve - manufacturer of transformers.]]> Basic parameters:

  • Rated secondary current: 1A or 5A;
  • Installation location: indoors;
  • Ambient temperature from -5°C to +50°C;
  • Altitude: ≤ 3000 m above sea level;
  • Insulation class B;
  • Protection grade Ip20

Description:
BTI series current transformers are designed for operation in AC circuits with a rated voltage of up to 660V and a frequency of 50–60Hz. They enable accurate measurement of current and electrical energy in metering systems.

BTI current transformers comply with the requirements of standards PN-EN 61869-1:2009 and PN-EN 61869-2:2013-06.
