From discharge voltage drop does not represent the starting point of continuous voltage landing Δ U4, but from straight line
part of the curve as the auxiliary line extended to the starting point and discharge cross get Δ U4.

B, The leakage current measurement should be rated temperature and rated voltage
(UR).Reached 95% after maximum 30 min charge time charging voltage and charging time from 30 min (1 f) or less, 1 h (1 f) or
higher, 2 h (10 f or higher), 4 h (20 f) or higher, 72 h (120 f) or higher in the choice.
C.Stable power supply, such as dc regulated power supply should be used.
D.Through the protection under 1000 Ω resistance to capacitor voltage.
E、Equipment：resistance multimeter
Self-discharging
A, Measuring method（refer to figure 7）
Before this measurement is made, the capacitors shall be fully discharged . Discharge procedure shall take 1 h to 24 h . Apply the
rated voltage UR directly to the capacitor terminals, without using a protective resistor. Unless otherwise specified by the
relevant specifications, charging time shall be 8 h, including maximum 30 min charge-up time to reach 95 % of the applied
voltage.
Disconnect the capacitor terminals from the voltage source. Unless otherwise specified in the detail specification, the capacitor
shall be kept under standard conditions for 24 h. The internal resistance of the d.c. voltmeter used shall have a value of at least 1
MΩ.
