NAME:MP - ECT135/83-10 electronic current transformer
Detailed introduction:

  Conventional current transformers have high insulation requirements, large size, heavy weight and high price; small dynamic range, saturation of transformers; easy generation of ferromagnetic resonance; inconvenient installation and maintenance of equipment. With the continuous advancement of digital substations and smart grids, electronic current transformers are becoming more and more widely used.

 

       ECT electronic current transformer is based on the research and development experience of our company for many years, combined with modern sensor technology and electronic technology research and development, using LPCT low power coil principle, small signal output without secondary conversion, direct access to the second As a substitute for traditional electromagnetic current transformers, the equipment can be widely used in three-phase bushings of on-column switches, ring network switchgear and on-column switches for metering, measuring and measurement of three-phase current and zero-sequence current. protection.

The principle of low power coil is as follows:

Current to voltage converter consist of a small Iron core and low loss electronics


Features:

 easy to curry because its small iron core: wide frequency response range, wide measuring range, good linearity, strong anti interference ability, small size and light weight;

Insulating material used is epoxy resin casting which is  safe, environment friendly, maintenance-free;

Combined transformer has Simultaneous measurement of three-phase current and zero-sequence current, protection signal sampling, simplifying system structure and reducing error sources;

 Aanalog voltage signal output: It can meet the needs of secondary equipment such as metering, measurement and protection.
