The benefit: With the retrofit of the control system, the operator is now capable to detect and isolated fault conditions on each incoming feeder individually without affecting power supply of the other operational feeders. Another improvement for the building owners is that if there is a power failure then there is only one break in the power. When the mains come back on, the sets will synchronize with the mains and transfer the load back smoothly so that there are no transients. Group Breakers and Mains Breakers can now also be controlled individually in auto and manual mode.
The level of complexity in this project have made ComAp the right choice, due to lower engineering efforts and set up time compared to an PLC system.
