If the core of CT is permanently magnetized then how will you demagnetize it?
To demagnetize the core of CT, A variable resistance of high value is connected across the secondary terminal of CT and full rated current flowing through the primary then resistance is gradually reduced to zero.
2. The core of HK series open type current transformers can easily be opened. Installation and connection can be available without cutting off the circuitry.
3. Based on above features, open type current transformer has more advantages in adding CT after maintaining and circuitry.
Feature:
1) One button clamp-on design, safe, easy to install, portable
2) Two built in fixing methods: Base; Busbar mounting
3) Wide inner window, allowing clamping of big cables or bus-bars
4) Wide range of sizes to accommodate all the existing installations.
5) Primary current from 5A to 5000A
Application:
1) Current measurement, monitoring and protection for electrical wiring and equipment.
2) Current and power measurement for electric motors, lighting, air compressor, heating and ventilation system, air-condition equipment and automation – control system.
3) Current, power and energy monitoring device.
4) Relay protection device.
