RELAY INFORMATION:

Features:Simultaneous phase-phase and phase- earth loop impedance measurement, withindividual numerical measuring elements for each type of fault and each distancezone, ensures fast and reliable fault detection.

Minimum operating time: 13 ms

Typical operating time of impedance measuring function: 28 ms.

Multiprocessor design guarantees high availability together with excellent possibiliesfor combining optional functions.

Numerical filtering and measuring technique ensure correct performance during CTsaturation and CVT transients.

Versatile local human machine communication (HMC) from the relay front paneltogether with two optional serial ports brings REL 100 close to the any user whereverthey may be located (in the substation, in the control centre or in the office).

Basic version of REL 100 includes:three forward and one reverse distance zones with individual setting of reach inreactive and resistive direction as well setting of earth return compensating factor.

Distance Protection:

----- Typical Operating Time = 28ms

----- Minimum Operating current = 0.2*Ir

----- Reset Time:Forward = 40msReverse = 60ms

----- Tripping mode: Three Phase / Single Phase tripping

----- Number of Zones: 3-forward / 1-reverse

----- Impedance Setting Range at Ir = 1.0AReactive reach = (0.1 150)Ohms/PhaseResistive reach:- Phase Phase = (0.1 150)Ohms/Phase- Phase Loop = (0.1 150)Ohms/Phase

----- Setting range of Timer = (0 10)s

----- Power Swing detection element: (0.1 150)Ohms
