Technical Parameters
1.Rated Voltage Level (kV): 0.23, 0.25, 0.4, 0.45, 0.48, 0.525;
2.Rated Capacity (kvar): 1~50;
1~10kvar: Single-ended terminal;
12.5~30kvar: Screw terminal;
35~50kvar: Delta terminal(＜400V);Screw terminal(＞400V)
3.Capacitance Deviation (uF): -5% to +10%;
4.Loss Tangent (tanφ): <0.1% (at Un, 50Hz, 20℃);
5.Inter-Pole Withstand Voltage: 2.15Un for 5s, without permanent breakdown or flashover;
6.Pole-Shell Withstand Voltage: 2Un + 2kV (or 3kV if below 3kV) for 10s, without breakdown or flashover;
7.Maximum Permissible Voltage:
At 1.1Un: Not exceeding 8 hours within 24 hours;
At 1.15Un: Not exceeding 0.5 hours within 24 hours;
At 1.2Un: Not exceeding 300 seconds;
At 1.3Un: Not exceeding 60 seconds.
8.Maximum Permissible Current: Capacitors can operate continuously at 1.3ln; considering the impact of overvoltage, positive capacitance deviation, and harmonics, the transient current does not exceed 1.43ln;
9.Discharge Device: After disconnecting the power for 180s, the capacitor's voltage drops below 50V.
10.Theoretical Lifespan: Under standard operating conditions, the average lifespan is greater than 100,000 hours.
