Differential-Protection Panelboards
The panelboards with ground protection system are laid out through differential modules and relays that make it possible to regulate the sensitivity of time delay (allowing selective differential protection), which serves to protect people, prevent risks of fire and destruction of electrical machines.
- Earth fault protection: : It controls earth fault current (residual), and the device disconnects the system at the programmed time.
- Ground continuity monitor: It continuously monitors the ground check and the ground wire in a circuit; the device disconnects upon: opening of the ground check cable, opening of the ground cable, or short between the two.
