Rated capacity : 1 30kvar 3. Capacitance tolerance: -5% +10% 4. Power loss tan 0.1% 5. Between pole voltage: 2. 15 times rated voltage is 5 second ,no permanence puncture or shine 6. Dielectric level : between cover add the voltage : 2 times rated voltage plus 2KV or 3KV ,please take height continue 10 second ,no puncture and shine 7. Max permit voltage :1.1 times voltage ,every 24 hours is not more than 8 hours ,1.15 times voltage ,every 24 hours is not more than 30 munites 1.2 times voltage ,it would not more than 5second (continue )1.3 times voltage ,not more than 1 minutes. 8. High permit current :it is permit to work within less than 1.3 times rated current ,as there are over voltage and capacitor positive deviation and harmonic the over current is not than 1.43 times rated current 9. Discharge component : inside put discharge register ,capacitor cut off power ,than discharge 3 munites electric ,so the voltage reduce to 50v 10. Standard: GB/T12747-2004 IEC60831-2002 Working conditions: 1Power capacitor should confirm left voltage reduce to rated voltage 10% to input again after the power was cut off ,normally it will need 200s almost. so it would choose the power controller which has input and reput lock time function after cut off the power. If choose normally power controller, it must install speediness discharge power equipment .it would not limited which use adopting same electric factor input and chip switch. 2. Altitude level is not more than 2000m. 3. Temperature type: -25/C low temperature, highest temperature is C type (it would not more than 50 the average of temperature is not more than 40 within 24 hours, one year average of temperature is not more than 30 ),power capacitor will work within good ventilate condition. It would not permit within sealing and installation condition
