Product Details

1. Ambient temperature : BFM type shunt capacitor -25°C~+45°C, BAM type filter capacitor -40°C~+45°C

2. Altitude: not exceed 1000m . If requested altitude above 1000m, have to been special supply on that.

3.Dielectric of between terminal for capacitor should bear one voltage test on below, duration time 10s.

a. power-frequency AC voltage : Ut (~) =2.15Un

b. DC voltage: Ut (-)=4.3Un

4. Capacitor should bear transition over-voltage with first peak not exceed 2.2Un and duration 1/2 period 2.6 For voltage up and higher harmonic, capacitor permit operate on stability over-current with effective value of 1.3In, but for capacitor with max positive deviation, over- current permit up to 1.43In..

5. Difference between measure capacitance and rated capacitance, not exceed -5%~+10% of rated capacitance, the ratio measured by max capacitance and min capacitance no more than 1.06 , which between each two line terminal of three phase capacitor.

6.On power-frequency rated voltage and temperature 20°C, capacitor tangent value of loss angle

(tg δ)≤0.0005

Note: if with discharge resistance and internal fuse , capacitor tangent value of loss angle permit increase 0.0001

7. Capacitor with discharge resistance, reduce from peak of rated voltage to below 75 V within 10min after break with power source. If requested reduce from peak of rated voltage to below 50V within 5min, it need special remind on order.

8. Internal of three phase capacitor with star-connection, each phase with discharge resistance
