th Record Notes for 6 Meeting of Nodal Officers for SEM Data Coordination held on 04.02.2021 Page 3 procedure is followed by TSTRANSCO. TANTRANSCO may seek the help of nodal officer of TSTRANSCO for further guidance in this regard. i. Goa informed that they had tried to resolve the time drift issue of the meter installed at Xeldem but unable to fix it. Hence, Goa had approached PGCIL to resolve it and expected to rectify within 2 or 3 days. j. BHAVINI informed that 6 Nos. of faulty SEMs were reported in the month of March 2020. They had approached the OEM (M/s L&T) for repairing those SEMs, got it repaired by M/s L&T after lot of pursuance and put in service in October 2020. BHAVINI had requested M/s L&T that time itself for servicing/ time drift correction balance 12 meters. M/s L&T had informed that 6 No. of SEMs were faulty due to memory corruption. Balance meters may go out of service if they are attempted to service/time drift correction as they are of old version. M/s L&T had recommended to replace the SEMs with new ones. As per the OEM’s suggestion, they are not able to attempt for time drift correction. Their management is not agreeing for the OEM as recommendation i.e. replacement of SEMs in bulk. Since M/s L&T was not accepting to service the meters, BHAVINI requested SRLDC/PGCIL to recommend M/s L&T for correcting the time drift of SEMs. k. SRLDC informed that earlier 6 no. of SEMs were failed and BHAVINI was not able to download the data. Hence, SRLDC had requested to replace the meters. However, BHAVINI had stated that SEMs had been repaired by M/s L&T. l. SRPC stated that it is the responsibility of BHAVINI to keep the time drift errors within the permissible limits as specified by SRLDC. BHAVINI was requested to take up again with the OEM for time drift corrections at the earliest. In case time drift correction cannot be done, the recommendation of the OEM may be followed in this regard in order to keep the time drift errors within the permissible limits. It was clarified that as per Central Electricity Authority (Installation and Operation of Meters) Regulations, the operation, testing and maintenance of all types of meters shall be carried out by the generating company. SRPC requested SRLDC to take up the prolonged issue of substantial time drift errors at BHAVINI with the Station Director, BHAVINI as recommended in the 5th SEM Nodal Officers meeting held on 22.07.2020. SRLDC agreed to take up with Station Director, BHAVINI. m. SRLDC apprised that few SEMs at Kaiga GS & MAPS have time drift more than 5 minutes. n. Kaiga GS informed that they were facing some issues with DCD, hence unable to adjust the time drift. o. SRPC/SRLDC stated that there are also other ways of adjusting the time drift, hence requested Kaiga GS to contact the OEM instead of depending on DCD for time correction. p. MAPS informed that they would correct the time drift of SEM on Acharapakkam Line in few days. q. PGCIL, SR-I informed that there may be typo error while uploading the statement for Khammam & Munirabad SS and would revert back after checking.
