LO-ZCT402 CBCT zero sequence current transformer

 

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.
