New Delhi: Andhra Pradesh Eastern Power Distribution Company Limited’s (APEPDCL) Chairman and Managing Director K Santhosha Rao inaugurated the Real-Time Data Acquisition System (RT-DAS) control system under the Integrated Power Development Scheme (IPDS) of the government of India as part of “Azadi ka Amrit Mahotsav.” Power Finance Corporation (PFC) is the Nodal Agency for the IPDS scheme.

The inauguration ceremony took place at APEPDCL Corporate Office, which is located at Seethammdhara in Visakhapatnam. Other officials and dignitaries present on the occasion were APEPDCL Directors K Rajabapaiah, B Ramesh Prasad, D Chandram, and CGM (IT) C Srinivasa Murthy, PFC’s Chief General Manager (PR) S Srinivasa Rao and General Manager (IPDS) Ashok Rathod. Other officers from APEPDCL were present.

Speaking at the event, Rao said that the project, which was sanctioned in December 2018, was completed in September 2021 at a cost of Rs 4.80 crore. RT-DAS has been implemented in 116 sub-stations of 33/11kV capacity and 437 feeders of 11kV capacity that will cater to 36 IPDS town areas.

The required hardware and equipment Feeder Permitted Terminal Unit (FRTU Panels), Multifunction Transducers (MFTs), etc were installed for all the 11KV Feeders. By implementing the RT-DAS project in APEPDCL, the real-time data, i.e. voltage, current, power, planned and unplanned interruptions from 11KV Town feeders will be available for measurement of SAIDI/SAIFI in all 33/11KV Sub-stations of 36 RAPDRP and IPDS Non-SCADA Towns (i.e. excluding Visakhapatnam). This will also enable an energy audit.


In the RT-DAS application, data is being captured using FRTUS (Feeder remote terminal Units) and MFTS (Multi-Function Transducers). The major highlight of this system is that just by having a glance at the RT-DAS dashboard, the management will be able to know the current situation about the power supply in all the 437 feeders of the DISCOM. It will also enable the DISCOM to understand whether a particular feeder is down due to a fault, thereby leading to an unplanned outage or planned maintenance activity.

Rao noted that with the launch of the RT-DAS control system, an uninterrupted power supply to the consumers will be a possibility.
