FIELD: remote protection, faulty phase selectors, ground detectors, networks with any neutral design (dead-grounded, insulated, compensated). SUBSTANCE: phase voltage and currents are measured at starting end of line, first and second reference values are shaped from them and by their conversion, mutual active power is determined as parameter at ground fault point under check. EFFECT: enlarged functional capabilities. 18 dwg
