Question：
1 S& Y$ s, D0 e, S4 ZWhen 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.8 o8 j3 D& T( y, `, [; t
Decision:# ~3 F4 r  [- Y! i+ K
In case the resistor is an integral part of the capacitor, the resistance is to be considered.
