Abstract (en)
[origin: WO9709624A1] A voltmeter for medium/high-voltage installations having a surface wave device (21) as the actual voltage measuring component. Said device (21) is inserted into a prior art impedance voltage divider (5, 6) in such a way that both electric high-voltage insulation is ensured and current supply problems in the voltage measuring component at high potential cannot occur.
