Introduction

In electrical systems, there is always the possibility of downtime due to operating errors, environmental conditions, lack of maintenance, or overcurrents or short circuits from atmospheric discharges. A ground fault occurs when one of the system phases directly touches the ground or any grounded metal part. Ground faults have different origins, but are more commonly degraded insulation, physical damage to the insulation system, or excessive transient or steady-state voltage stress on the insulation. These problems can be caused by humidity, atmospheric pollution, insulation degradation, mechanical stress, etc. While the aforementioned situations can be avoided with a good maintenance schedule, there is always a potential risk of failure, usually during installation or major maintenance to the equipment.

High accuracy qualified

On the basis of the existing mature technology, the High Precision Zero Sequence Current Transformer selects more high-quality raw materials, combined with the optimized shape design, the test accuracy is effectively guaranteed, which is better than the national standard requirements: 0.5%, and the accuracy can reach 0.2% for special requirements .

The High Precision Zero Sequence Current Transformer combines the optimal magnetic circuit design and fully considers the necessary space requirements to ensure balanced testing. If necessary, the balance characteristic can reach 5mA-50mA under the specified detection conditions. Fully meet the detection circuit requirements.

At the same time, High Precision Zero Sequence Current Transformer can be used for main loop current detection, thermal power monitoring current, detection current range 50A-2000A, the accuracy is better than 0.5 when the secondary output is 5A, the accuracy is better than 0.2 when the secondary output is 1A, the measurement When the current is large, it can output mA level weak signal, and the accuracy is better than 0.1 level.

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.
