Restricted earth (87G) - Models PD300-2 and PD300-G

This function is applicable when one of the transformers windings is grounded. The function compares the residual current with the current flowing through the grounded transformer. Should the difference between both currents, following the application of the corresponding transformation ratios, exceed the set threshold, a trip signal is issued. The direction is taken into account when allowing the trip.

Phase overcurrent protection (50/51) - All models

A back-up protection for external or internal transformer faults. In the event of such faults not being cleared by the primary protections, the overcurrent protection acts. Serious damage to the transformer would be produced in the absence of such protection. Each winding is equipped with two instantaneous levels and one timed level.
