Functions and Applications:
ABB RET650 is a digital output module designed for automatic voltage regulation.
It provides fast and selective protection, monitoring, and control for various transformers, such as double-winding transformers, three-winding transformers, auto-transformers, shunt reactors, and booster transformers.
Features include low impedance restricted earth fault protection, multifunctional phase-to-phase, earth fault, positive sequence, and zero sequence overcurrent protection.
It can output pulse signals for pressure release, light and heavy gas, and excessive oil temperature through IED devices.
