Spesifikasi capacitor bank alvifar
Electrical Protection Device :
- Self-healing dielectric : this self-healing property is connected with the characteristics of the metal deposit which forms the electrode and the nature of the insulating support (polypropylene film)
- This special manufacturing technique prevents breakdown of the capacitor due to electrical overvoltages.
- In fact overvoltages perforate the dielectric and cause discharges which vaporise themetal near the short circuit, thus instantaneously restoring the electrical insulation.
- Internal fuses : one per winding.
- Pressure monitoring devices if an electrical fault cannot be overcome by the film self-healing or by means of the electric fuse, gas is emitted, causing a membrane to deform and disconnecting the faulty winding.
These three protection devices, together with the vacuum coating of the windings (technique patented by ALPES TECHNOLOGIES), result in a very high-tech unit.
Discharge resistors :
- Fitted inside (except by special request), these discharge the unit in accordance with current standards (discharge time, 3 minutes).
Loss factor :
- ALPIVAR have a loss factor of less than 0,1 x 10-3.
- This value leads to a power consumption of less than 0.3 W per kVAr, including the discharge resistors.
Capacitance :
- Tolerance on the capacitance value : ± 5%.
- Our manufacturing process, which avoids any inclusion of air in the coils, ensures excellent stability of the capacitance throughout the service life of the Alpivar capacitor.
- Max. permissible voltage: :
1,18 Un rated - Max. permissible current :
Standard type : 1,3 In
Type H reinforced : 1,5 In - Insulation class :
Withstand at 50 Hz 1 min : 6 Kv
1,2/50μs impulse withstand : 25 kV
Standards :
- Alpivar capacitors comply with :
- French : NFC 54 108 et 54 109
- European : EN 60831-1 et 60831-2
- International : CEI 60831-1 et 60831-2
- Canadian : CSA 22-2 N° 190
- End of life performance tests performed successfully in EDF and LCIE laboratories.
Temperature class :
- Alpivar capacitors are designed for a standard temperature class -25°C / +55°C.
- Maximum temperature : 55°C
- Average over 24 hours : 45°C
- Annual average : 35°C
- Other temperature classes on request.
