residual voltage winding potential transformer

Voltage transformer is suitable for the rated frequency of 50Hz or 60Hz, rated voltage of 3-10KV AC power system, for electric energy measurement, voltage monitoring and relay protection.

General:

Voltage transformer is suitable for the rated frequency of 50Hz or 60Hz, rated voltage of 3-10KV AC power system, for electric energy measurement, voltage monitoring and relay protection.

Key Feature

Completely closed structure, the winding is epoxy resin full vacuum casting full edge structure.
The core is made of high quality silicon steel sheet.
The transformer is insulated by epoxy resin, and the product is small in size and light in weight, and the installation only takes up limited space.
All windings are completely cast in epoxy resin, with excellent insulation against shock and mechanical pressure, and can protect the windings from moisture.
The primary winding lead terminal is marked A,N; The mark of the measuring terminal of the secondary winding lead line is a, n, the mark of the protection terminal is da,do are clearly marked on the pouring body. There is a ground bolt beside the grounding mark on the clamp for grounding, and the lower bracket for installation.
