Section 14 in Tamil Nadu Electricity Regulatory Commission - Tamil Nadu Electricity Distribution Standards of Performance Regulations, 2004
14. Permissible limits for voltage and frequency variations.
- The limits of permissible variations in voltages at various levels have to be fixed on the basis of existing network, spare capacity, etc., and always be improved with system improvements, capacity generation and various other related factors. Hence, even though the ideal situations would be different, the bandwidth of variations has to reflect the actual condition and has to be specified after periodical reviews. Accordingly, the Commission, from time to time, will order the permissible limits for voltage variations.The frequency variations shall be governed by the National / State Grid Code and hence not specified under this regulation
