|
Minimum distance between units |
CLMD13-33 : 20 mm (25 mm for units > 30 kvar). |
|
and wall |
CLMD43-53-63-83: 50 mm. |
|
Losses (discharge resistors included) |
< 0.5 Watt/kvar for 380 V rated voltage and above. |
|
Tolerance on capacitance |
0 % + 10 %. |
|
Voltage test |
Between terminals: 2.15 Un for 10 seconds. Between terminals and earth: 3 kV for 10 seconds for UN < 500 V and 4 kV for 10 seconds for UN > 500 V. |
|
Lightning impulse voltage test |
CLMD13-43-53-63-83: 15kV. CLMD33S: 8kV. |
|
The acceptable overloads are those |
Overvoltage tolerance: 10% max. at intervals. |
|
specified in IEC 831-1&2 |
Overcurrent tolerance: 30% permanently. |
|
|
Maximum overload: stable operation at 135% of the nominal rating (generated by overvoltages and harmonics). |
