Description
Description
Introduce

The voltage transformer of this type,following the three-phase five -columm voltage transformer .Ferromagnetic burned a lot of the public nuisance and the successful development of an anti-ferromagnetic resonance voltage transformer in order to eliminate a result of varying degrees of Park power system grounding transformer.

The product is 100% ground fault occurs in the system,can still be a long time normal operation .While protecting the windings of the 100v voltage to the relay .System during normal operation to protect the windings output voltage<10V.

Features
Voltage transformer of this type of epoxy resin cast semi-enclosed,fully insulated structure.
Small size,adaptability to climate,anti-divider frequency resonance,not excitation burned ,the transformer core next to the iron yoke of the core structure ,the use of high-quailty cold-rolled silicon steel sheet stacking a rectangular exposed the air,the windings with poxy casting insulation,three-phase integrated structure.

Explanation of connection

1.To prevent the CT to be burnt out,the primary and secondary contacts are forbidden to be connected to the earth except the marked one.

2.The primary contact N is connected directly to the earth,the censorial windings of the secondary earthing is connected with relay or used as computer supervisory control system. This product is forbidden to switch in the primary harmonic elimination device and the secondary computer harmonic elimination device;otherwisethe CT will be burned out.
