HEYI ELECTRICAL Open loop hall current sensor for IOT
KCT-16L

KCT-L series dismountable hall effect current sensor is an open loop device based on the measur i ng
principle of the hall effect, with a galvanic isolation between primary and secondary circuit. It provides accurate electronic measurement of DC, ACor pulsed currents.
Directions for use
When the current will be measured goes through a sensor, the current will be measured atthe output end. (Note: The false wiring may result in the damage of the sensor)
Custom design in the different rated input current and the output current are available.
Application
1.Inverters, frequency control devices.2. Electric locomotive, grid monitoring.3. PV new energy.
4.Industrial application.
Features
1.Highaccuracyand good linearity
2.Low temperature draft, wide frequency band.
3.Short repsonse time, high strong anti-interference capability.
4.Strong overload ability.

In Egypt you must pick the CTs with care. The need is strongest, in Cairo, Alexandria and Suez because the electric grid often changes, gets hot and carries loads. When the CTs are not stable or not accurate the safety system can fail. I have seen that the switchgear, the fuse breakers and the CTs… Continue reading How to Choose the Right Current transformer in Egypt
