Tutorial: Complex Busbar Protection Application
WebJul 7, 2024 · What is check zone in busbar protection? As a further measure, the so-called check zone also known as overall protection has proven to be very successful. This measuring system functions as a protection of the entire busbar arrangement and is entirely independent of all isolator status information. WebThe busbar protection DRS-C2BB is operating according to the current differential principle with through-fault current bias. Three independent sections can be evaluated and to increase reliability against false operation for each feeder a check zone and a fast overcurrent interlock is included into the scheme. Webprotection of busbar sections from four up to 24 CT inputs. All variants have two low-impedance differential protection zones and check-zone. You can use the graphical configuration tool Protection and Control IED Manager PCM 600 to easily and intuitively adapt the pre-configured REB670 IEDs to your specific busbar arrangement. ibis guaratinguetá telefone
