Working principle:
Hemei Electronics sells several different series of current transformers (CTs) in various window sizes, current ranges, and accuracy grades. Safe, low-voltage output CTs do not need shorting blocks because the internal burden resistor is always connected.
To select a CT, we recommend first deciding on a style, either a split-core (opening ) or a solid-core (non-opening) CT, then select the model you need based on the maximum load current you are measuring and the size of the conductor being measured.
Application：
High-voltage transmission lines/medium-voltage distribution networks/high-speed rail/underground mines/energy consumption monitoring/metallurgy/dock shore power/large pump industry/hydropower and wind power detection/water conservancy monitoring/new energy vehicles/smart power consumption/smart mines/civilian airports/others Industry application

Feature:
1. The self-powered CT is of open structure, easy to install and operate.
2. The inner diameter of the transformer can be selected according to the diameter of the primary high voltage line.
3. Transformers of different types and sizes can be matched according to the current of the primary side high voltage line.
4. Energy transformers and induction power modules are used.
5. Rational planning of load distribution according to the conventional operating values and power curves of the conductor currents.
6. Due to the magnetic circuit, there will be a slight ticking sound when the energy transformer is working, which is a normal phenomenon.
