Incazelo emfushane:
I-Impulse Voltage Test System isetshenziselwa ikakhulukazi ukwenza ukuhlolwa kwe-full wave lightning impulse voltage, ukuhlolwa kwe-chopping impulse kanye nokuhlolwa kwe-switching impulse kuma-HV apparatus afana nama-transformer, ama-surge arrester, ama-insulator, ama-bushing, ama-capacitor, kanye nama-switch. Ingakhiqiza i-standard lightning wave, i-switching wave, i-chopping wave enobubanzi obukhulu be-voltage namandla.
Ihlanganisa izingxenye ezingezansi
● Ithebula Lokulawula Nokulinganisa.
● I-Impulse Voltage Generator.
● Iyunithi yokushaja ye-HV DC.
● Isihlukanisi samandla esinciphile
