The full-featured monitoring relay is used for 3-phase network control, network monitoring and protection, voltage regulation from a generator or hydropower plant.
DESCRIPTION
monitoring of 3-phase mains:
- voltage in 2 levels (undervoltage and overvoltage) in range 138-276 V (3x 400 V / 230 V) or 280-480 V (3x 400 V)
- phase asymmetry (can be switched off )
- phase sequence
- phase failure
adjustable function „MEMORY“
function of second relay (independent / parallel)
adjustable delay for short peaks for each level independently
