Shortage Current to ground protection (g)
leakage Current to ground protection (g) - optional
Protection against shortage current to ground, with
feature of inverse time or defined time
1. Current Ig
- Adjustment of Range: (0.2-0.3-0.4-0.5-0.6-0.7-0.8-
1.0-Off) xIn
2. Performance time tg
- Adjustment of Range for inverse time: (0.1-0.2-0.3-0.4)s
- Adjustment of Range for defined time: (0.05-0.1-0.2-
0.3-0.4)s
3. The unit performs as per the vectorial sum between
currents of the phases R, S, T and neutral N.
4. The unit can also operate instantaneously by
means of the function ZSI.
5. This protection function uses the internal CTs.
Protection against leakage current to ground, with
feature of inverse time or defined time (optional for the
A,P and S type protection units)
1. Current Ig
a) Toroidal CT of the ACW line
- Adjustment of Range: (0.5-1-2-3-4-5-10-20-30-Off)A
b) Generic toroidal CT
- Adjustment of Range: (0.5-1-2-3-4-5-Off)A
2. Performance time tg
- Adjustment of Range of alarm time: (140-230-350-800)
ms
- Adjustment of Range of performance time: (60-140-230-
350-800)ms
3. The unit performs as per the current of the toroidal CT.
