The UHV-545 records lightning strikes and performs online leakage-current monitoring of surge arresters. It employs a double-valve measurement structure and can generate defined output surge-current waveforms (8/20 μs) with amplitude >100 A. An integrated ammeter enables direct leakage-current checks on-site.
