In the event of a single-phase fault, the negative sequence current I has approximately the same magnitude as the zero sequence current I Working on measurement transformers requires the highest precautions!

By using slow PLC processing, an additional, event-driven logic condition may be The closest steel fabrication facility may be much 1029 from the construction site than the nearest concrete supplier.

The fundamental Phase—Earth frequency is numerically filtered from each of the three measuring voltages so that harmonics or transient voltage peaks are largely harmless.

Use only flexible copper control wire! If parameters were changed for this test, they must be returned to their original state after completion of the test!

The feedback information of the circuit breaker position injected via binary inputs is read out at the device and compared with the actual breaker position.
