Fast and cost-effective solution for defective HR interfaces
1. Initial situation
HR interface: repeat check required every 6 years; low life expectancy due to high insulation requirements.
2. Mounting CAPDIS-PI
3. Possibly adjust capacity
If the HR interface is defective, i.e. not all 3 full flash arrows appear with a standard CAPDIS-PI at the pending nominal voltage, an adjustable CAPDIS-PI RR4 is set up. The defective phases are reconfigured via DIP switches until three full flash arrows are displayed. No external measuring device is required for parameterization.
4. Result
- Repeat test-free voltage test system according to VDE 0682 T 415
- Testing for voltage-free without additional equipment
- Simplified earth fault detection at a glance
- Integrated self-test function
Bericht eines Anlagenbetreibers nach der Umrüstung auf CAPDIS-PI:
Defekte kapazitive HR-Schnittstellen, die bereits einen Isolationsverlust des kapazitiven Teilers angezeigt hatten, konnten durch Installation des speziellen Retrofit-Geräts Capdis-PI-RR3 in etwa zehn Minuten wieder komplett ertüchtigt werden, ohne dass die Anlage abgeschaltet oder zerlegt werden musste.
Durch die Komplettsanierung der hochohmigen, kapazitiven Schnittstellen mit den Capdis-PI-Spannungsprüfsystemen von Kries-Energietechnik haben die wir die Lebensdauer der kapazitiven Teiler erheblich verlängert, ohne die Lebensdauer der Schaltanlage zu vermindern.
