Activities proposed by TANGEDCO to improve the infrastructure of the Power Distribution System
Posted on: 15/Jul/2019 11:53:09 AM
TANGEDCO has taken all initiatives to provide uninterrupted power supply and in case of interruption, reduce the same to minimal effect. As a part of this objective, TANGEDCO has proposed to replace the existing distribution transformer structures with the ‘Ring Main Unit’ (RMU) in suburban areas of the city in a phased manner.
Ring Main Unit
The ring main unit is a sealed and insulated compact switchgear unit used for electric power distribution. About this device, a senior TANGEDCO official shared:
“The insulation may be air, oil, or gas, and the switch used to isolate the transformer may be fusible or circuit breaker. The ring main unit is a safe, easy to install and maintenance-free switchgear which improves the reliability of utilities and uptime of the network, besides reducing operational costs.”
The proposal
This above conversion to RMUs proposed by TANGEDCO is mainly in order to ensure safety and to prevent electrical accidents. In this regard, the official shared again:
“A detailed project report approval has been obtained for the replacement of 13,810 transformer structures at a total cost of Rs 1,819 Crores. The funding for this project is by the Rural Electrification Corporation (REC). The tender for replacing 5,692 transformer structures has been opened and is under scrutiny. This project will also be completed in 2020-21”.
Modified Pillar Boxes
Apart from the above initiative, TANGEDCO has also proposed to replace the pillar box with high rupturing capacity (HRC) fuse MS six-way pillar box in Chennai region in a phased manner in order to minimise power interruption during natural calamities.
An official informed that a detailed project report has been approved for the replacement of 33,225 exiting pillar boxes at an estimated amount of Rs 389 Crores funded by REC.
