Introduction

In the electrical systems always exists the possibility of having shutdowns due to over currents or short circuits produced by operation mistakes, ambient conditions, lack of maintenance or atmospheric discharges. Ground fault it occurs when one of the system phases get on direct contact to ground or to any metallic part that is grounded. The ground fault has its origin on different ways but the more common are reduced insulation, physical damages to insulation system or excessive transient or steady-state voltage stresses on insulation. These problems can be produced due to moisture , atmospheric contamination, insulation deterioration, mechanical stresses, etc. Although the situations mentioned before can be avoided following a good maintenance Schedule, always exists the latent risk of a fault, commonly during the installation or major maintenance to equipment.

High accuracy qualified
This series of products are on the basis of the existing mature technology, choose more high quality raw materials and combined with the optimization of the shape design, test accuracy gets strong guarantee and better than the national standard requirements: 0.5%, for special requirements,  accuracy can reach to 0.2%.

 This project combines the optimal magnetic circuit design, and take full account of the necessary space requirements, so as to ensure the balance test. If necessary, the balance property can be in the specified detection conditions to achieve 5mA-50mA. Fully meet the detection circuit requirements.

At the same time, this series of products can be used for main circuit current testing, and fire power monitoring current, detection current scope from 50A-2000A, Accuracy is better than class 0.5 when secondary output at 5A .Accuracy is better than class 0.2S level when secondary output at 1A,

When measure high current , mA level weak signal can be outputed,the accuracy is better than class 0.1 

 

Custom-made

The module box can be customized according to the customer's requirement. Or optimize the box in the original basis. We will do our best to support these optimizations.

All module boxes can be re-designed and developed according to customer needs. Even the residual current transformer can also be re-designed according to special needs of customers.
