Low voltage capacitor voltage 0.45 and 0.4 What is the difference between usage
0.45 capacitor used in the voltage level is high (for example, the transformer low voltage side voltage may reach 415V), with a tuned reactor (tuning reactor will increase the capacitor terminal voltage) situation; Note that the actual capacity of 0.45 capacitor nominal capacity (Actual voltage / 0.45) ^ 2 times;
0.45 and 0.4 capacitors are capacitors that rated the line voltage of 0.45kV and 0.4kV; they are suitable for 380V voltage systems, the difference lies in their pressure rating;
Can be used in the low-voltage three-phase power lines on the line, but the level of different pressure, connected to the 400V line, 450V capacitor capacity is 79% of rated capacity, 400V capacitor capacity is rated capacity. In the use of life on the 450V longer than 400V
