The NACBL is solution for networks with harmonic waves resulting
e.g.
from use of frequency inverters, where automatic power factor
compensation with blocking filters is necessary.
The NACBL has a cassette structure, where all the
components for each step have been placed in a cassette. This solution
results in an easily expandable system which is also easy to maintain.
The busbar system has been placed in a completely
separate compartment making the system safe to install and use.
The standard sizes for NACBL PFC-system with blocking
filters are 100 - 300kVAr with steps of 25 or 50 kVAr. Each cabinet can
have up to six cassettes/steps. The protection class is IP30. Larger
systems can be done by connecting several cabinets. The controllers are
either electronic or microprocessor-based with 6 - 12 steps.
