Hello Group, In EN61010, section 6.3 says, "If the voltage exceeds the value listed in 6.3.1 or 6.3.2, the current and capacitance shall be measured."
I understand how to measure current (6.3.1.2) with the circuit in Annex A, but how do I measure Capacitance for section 6.3.1.3? It doesn't seem right to try and measure a complex circuit while powered off with a conventional capacitance meter. How else can this be done? Any help would be appreciated. Brian Kunde MORE INFORMATION I have an instrument that places 2500 volts in an area that the operator has to have access to. We are attempting to verify that this circuit meets the requirements of a limited current circuit by applying the requirements of section 6.3.. When applying the loading circuit described in Annex A the voltage is loaded down to a point where the HV circuit shuts down. To my understanding, doing so meets the requirements of 6.3.1.2.. But, when you first apply the loading circuit to the HV circuit you see a small arc or spark, so I'm assuming there is some discharged energy that exists before the HV Circuit shuts off. I assume this issue would be covered under the Capacitance measurement in section 6.3.1.3 but I have no idea how to make this measurement.
