Bushing current measuring transformers

Measuring current transformers are designed for large-scale conversion of alternating current for the purpose of its further measurement in networks with a frequency of 50 Hz and a rated voltage of up to 0.66 kV inclusive. Transformers are used in commercial metering schemes for electrical energy (current transformers for meters of active electrical energy) for settlements with consumers, as well as in metering and protection circuits.

Magnetic cores of measuring current transformers TPP-N-0.66 are made of nanocrystalline alloy and have the following advantages over current transformers based on electrical steel cores:
  • resistance of metrological characteristics to direct current magnetization;
  • increased energy efficiency of custody transfer (lower losses) due to higher electrical resistance of the material and reduced losses due to magnetization reversal of the core;
  • long service life while maintaining metrological characteristics.

Magnetic core made of nanocrystalline alloy provides long-term stability of parameters for more than 25 years.
