TOP Current Transformer Manufacturer- Since 1998 TOP Current Transformer Manufacturer- Since 1998
UK Series split-core current transformer has been specially designed to facilitate their installation in new or already existing networks.
They may be installed without opening any cable or bus-bar circuit.An internal precision resistor across the secondary winding of the CT provides a low safe voltage output.It can save time and the installations costs.
Features
Doubie-screw fastening,safe,easy to install,portable.
Wide inner window,allowing clamping of big cables or bus-bars.
Wide range of sizes to accommodate all the existing installations.
Application
Current measurement,monitoring and protection for electrical wiring and equipment.
Current and power measurement for electric motors,lighting,air compressor,heating and ventilation system,air-condition equipment and automation-control system.
Current,power and energy monitoring device.
Relay protection device
