Product features and working principle 

1. Structural aspects
The product adopts the through-wall epoxy resin casting insulation design, which can be divided into three types: single-turn type, multi-turn type and bus-bar type, which can be applied to the needs of various products.
2. Insulation level
LA-10Q current transformer adopts high-performance imported electronic components, insulation level: 12/42/75kV, reaching the national standard.
3. Main role
LA-10Q current transformer is mainly used for electric energy measurement, current measurement and relay protection.
Working principle of current transformer:
LA-10Q current transformer is based on the principle of electromagnetic induction.
A current transformer consists of a closed iron core and windings. Its primary winding has a small number of turns, and it is connected in series in the line of the current to be measured, so all the current of the line often flows through it. When working, its secondary circuit is always closed, so the impedance of the series coil of the measuring instrument and the protection circuit is very small, and the working state of the current transformer is close to a short circuit.
