Description Voltage Frequency 1. For HT system :- +/-1% +/- 3% 2. For LT system +/-1% +/-3% 3. For Control voltage AC +/-1% +/-3% 4. For Control voltage DC +/-1% NA In case of sensitive equipment hich require more stringent qua lity of power supply with lesser variations to achieve the desired performanc , shall provide the necessary regul ator/stabilizer required for efore such equipment. The rated short circuit withstand duration for 3 kV &6.6 kV an 4 including MCCs will be 3 sec and 1 sec respectively. Each 3/6.9kV Transformer along with the incoming 3kV and 6.6k feeders cable size shall be designed based on the ollowing load considerations. . HT Compressor 3nos (work ing) & 1 no (standby) . LT load- As Required However the Power Transformer ,LT Distribution Transformer min imum ratings are specified in the Specification. The Cable sizes for 6.6 kV sh all be minimum 3Cx2 Sqmm and niformly used in the plant where LT cable maximu 3CX2 Sqmm shall be used.
