  Insulating Resistance

The value measured by applying DC 500V insulation resistance tester between all terminals and snap ring withinsulating sleeve ≥100MΩ

    Insulating Voltage

Apply AC 2,000V between all terminals and snap ring with insulating sleeve for 1 minute and no abnormality appears.

          Durability

Apply rated ripple current on capacitor with voltage not more than rated voltage under 105°C environment and apply rated voltage for 3,000 hours, then recover to 20°C environment and the test results should satisfy the requirements as below
Capacitance change rate (C)≤initial value±15%
DF(tgδ)≤200% of inital specifications value
Leakage current ≤inital specifications value

High-temperature Zero Load Feature

capacitor is kept in 105°C environment for 1,000 hours, then test in 20°C environment and the test results should satisfy the requirements as below
Capacitance change rate (C)≤initial value±15%
DF(tgδ)≤150% of inital specifications value
Leakage current ≤inital specifications value
(Voltage pretreatment should be done before test: apply rated voltage on both ends of capacitor through a resistor about 1,000Ω for 1 Hrs, then discharge electricity through 1Ω/V resistor after pretreatment. Place capacitor under normal temperature for 24 Hrs after total discharging, then starts test.
