GROUP 1 – DISTANCE ELEMENTS

OTHER PARAMETERS

Serial Cmp.line

Serial Compensated Line: If enabled, the Directional Line used in the Delta Algorithms is set

at 90° (Fwd = Quad1&4 / Rev = Quad 2&3).

If disabled, the Directional Line of the Delta algorithms is set at -30° like conventional

Overlap Z Mode

Overlap Z Mode: If enabled, for a fault in Zp (fwd), then Z1 & Z2 will be displayed in

LCD/Events/Drec – The internal logic is not modified.

Z1m Tilt Angle

Z1p Tilt Angle

The settings dealing with the tilt ('Z1m Tilt Angle', 'Z1p Tilt Angle', 'Z2p/Zp/Zq Tilt Angle')

and the evolving forward zone detection to zone1 (to avoid a Z1 detection in case of

impedance locus getting out from the quad, due to remote CB operating) but crossing the

Z1 before being out from the quad (with enough points that a Z1 decision) can be confirmed

if that timer has been set to 0ms.

Z1m and Z1p Tilt Angle: The tilt angles can be independently set (±45°) for phase-to-ground

and phase-to-phase setting.

Z2/Zp/Zq Tilt Angle

Tilt characteristic for zone 2, zone P and zone Q (common setting for phase-to-ground and

phase-to-phase).

Fwd Z Chgt Delay

This time delay is set to prevent maloperation due to zone evolution from zone

by CB operation.
