BijliDost | accuracy limits of Electronic Meters

According to the Central Electricity Authority (CEA) and the Bureau of Indian Standards (BIS) guidelines, the permissible error limit for electronic meters for domestic consumers under field (meaning site) conditions, is governed by IS 15707:2006-i.e. (+/-) 2.5%. Similarly, the permissible error limit for electronic meters under reference (meaning lab) conditions is governed by IS 13379:1999-i.e. (+/-) 1%. Putting at rest the needless controversy – once-and-for-all, a Division Bench of the Hon’ble High Court of Delhi, headed by Chief Justice Hon’ble Mr. Justice Manmohan reaffirmed these accuracy limits of electronic meters. This significant judgment was passed by the High Court in the BRPL (Appellant) Vs V.K. Jain (Respondent) case on 30 July 2009.

Earlier in April 2008, a Single Judge of the Hon’ble High Court had passed an order, holding the applicability of the Standard IS 13379:1999 for testing of electronic meters under both Field conditions as well as Lab conditions. Subsequently, BRPL had filed an appeal before a Division Bench of the High Court.

India has one of the world’s most stringent norms for Meter Accuracy, {See Box}

Country	Permissible Error Limit (+/-)
