KSEB To Implement HVDS
On Apr 07, 2015
|Trivandrum: For the first time in the state, Kerala State Electricity Board (KSEB) has introduced high voltage distribution system (HVDS), in place of low voltage distribution system, for giving electrical connection to households. The consumers from Manchadi under Peyad electrical section would avail high quality power supply in the initial phase.
This new system is expected to lower the transmission loss and also reduce the chances for frequent power failure. In fact low tension (LT) electricity lines are not used in this system. Instead of LT lines, power is taken from 11 KV lines and stepped down with smaller transformers and the service wires transfer it to the households to the transformers fixed on the 11 KV posts.
While transmission loss of power in LT lines is between 8 and 10 per cent, HVDS has only one per cent loss. Although the initial cost for the facilities for HVDS is high, it is profitable in the long run. Twenty four transformers of 15 KVA each have been set up for the HVDS at Manchadi instead of the three low tension feeders under the 160 KVA transformers.
HVDS was being experimented in the Peyad electrical section for a year and the success of the experiment made way for the permanent HVDS. KSEB places step-down transformers at selected places and manages the supply of power from these transformers through LT lines. The HVDS facility is now available within a radius of around 2km in the initial phase.
