Question：
When checking the value of the tangent of loss angle against the value declared by the manufacturer, should a discharge resistor encapsulated with the capacitor be considered? This is relevant because in a 2 uF capacitor with a discharge resisitor of 1 MΩ, the tangent can duplicate its value.
* P  R  Q* M8 ?$ gDecision:
In case the resistor is an integral part of the capacitor, the resistance is to be considered.
