SV Measurement (Step Voltage)
6.7.1 Step Voltage
SV : Step Voltage
This is a test based on the principle that an ideal insulation will produce
identical readings at all voltages, while an insulation which is being over
stressed, will show lower insulation values at higher voltages. During the
test, the applied voltage incrementally steps by a certain voltage taking
successive 5-time measurement. Degradation of insulation may be doubt
when insulation resistances become lower at higher applied voltages.
6.7.2 Measurement Setting Items
1. Select the “SV（Step Voltage）” on the Mode Selection Screen. Refer
to
Basic Operation (=>P.21) and operate the Screen.
2. Set Voltage values.
