Recovery Voltage Meter

More Information


The Recovery Voltage Method is based on established knowledge: the phenomenon of the polarization of oil/paper impregnated insulation.Many href="http://www.haefely-hipotronics.com/solutions/by-application/hv-component-testing/" €œhigh-voltage-working people €œ have made this painful experience: of short-circuiting a high voltage capacitor (which was previously charged with a direct voltage), of measuring a voltage more or less 0 V and so believing that the capacitor is completely discharged, of touching the connectors of the capacitor and of feeling a shock. This shock is due to the polarization of the insulation. By this method, insulation condition is examined by tracing the polarization spectrum from the results of the recovery voltage measurements.The instrument, the Recovery Voltage Meter model RVM 5462, which is the successor of the very well known model RVM 5461, effectively completes the range of the conventional insulation diagnosis methods, e.g. dissipation factor (tan delta) and partial discharge measurements, oil analysis, and so on.
