HV network, overvoltages, numerical simulation
The paper presents studies by numerical simulation and experiments carried out to determine the transient overvoltages and homopolar currents in an 110/24 kV network from Romania at net and intermittent ground of one phase the neutral being connected by transformer and compensation coil parallel with three-phase coil having commutable neutral point earthing during short-circuit test. Also the paper presents the preventive measures for limiting overvoltages.
