Schaffner updates its modular active harmonic filters – Ecosine Active Sync
Schaffner launches an updated version of its rack mounted active harmonic filter with higher efficiency and heat tolerance as we understand.
Schaffner reports:
The modular design of ecosine active sync always allows a suitable filter size to be supplied and, in addition, the 60 A modules can be easily fixed to the wall or integrated into system control cabinets. Simply slide in and wire up – a filter from up to 300 A per cabinet is ready.
ecosine active sync in detail
- Most effective harmonic mitigation up to 50th order (odd and even). Below 5% THID achievable even for mixed and dynamic load profile.
- Most compact and modular design. Flexible and easy installation.
- Robust, reliable and suits the broadest temperature (power module up to 50°C) range with full performance.
- High efficiency (< 2.3% losses) and very low acoustic noise.
- Only air cooling for all product variants with IP 20 power module, IP 21 (roof kit) and IP 54 cabinet version.
- Reactive Power Compensation
- Load balancing
- Modular ready to use, retrofit integration in slide-technology cabinet
- Ultra-flexible mounting and installation options
Active Harmonic Filter Application in Ba Na Hills, Vietnam
Here is a great showcase of the effects of applying active harmonic filters on a cable car installation made by Power More in Vietnam. Ba Na Hills Mountain Resort are holders of three Guiness Records – Longest single rope cable car system, Longest distance between stations and Heaviest cable roll. For Ba Na Hills, power quality is a question of safety and service quality. With total harmonic distortion 5 times higher than the national regulated level, Ba Na Hills were facing several problems.
- Station to station communcation was interrupted
- Power factor penalties
- Damaged PFC capacitor units
- Inerference with PFC controller
- Reduced motor effeciency in generator mode to 50%
Applying ADF Power Tuning active filters from Comsys to battle both power factor correction and harmonic filtering resulted in:
- Eliminated risk of PFC failures
- Eliminated power factor penalties
- Increased motor efficiency to 100%
- Improved cable speed
Schaffner use Active Harmonic Filters to Clean up Conference Center
In this case study of the Luzern Conference Center in Switzerland, Schaffner demonstrate the full utility of the active harmonic filter application. The active filters are distributed throughout the building to compensate not only harmonics but also power factor correction as well as load balancing.
Leave it to the Swiss to adapt to multifunctional tools.
