DRAFT TECHNICAL SPECIFICATION OF DESIGN,

MANUFACTURE, TESTING SUPPLY & COMMISSIONING OF SINGLE PHASE & THREE PHASE ELECTRONIC

PREPAYMENT METERS 1. FOREWORD

Electromechanical meters have been used on Indian Railway on large scale. These meter suffer from inherent drawback of

low recording, tampering and poor accuracy etc. The problems have been partly solved with replacement with the

electronic meters. The issues relating to bill generations, distribution and collection from the vendors continues to be a cause of concern as it results in delayed collection with

very low yield rate. Prepayment meters are a step toward solving these problems and therefore considered a viable

option for the purpose of metering. 2. SCOPE:

The scope of this specification covers design, manufacture, testing and supply of single phase and Three Phase

electronic, keypad prepayment meters with split unit and provisions for TOD (Time of Day) tariff and R.T.C. (Real Time

Clock).

The requirements of the online Vending/Transaction system

to be provided for the prepayment metering system are also covered in the scope.

3. REFERENCE STANDARDS:

The meters with accuracy class–1.0 are required for measurement of Active Energy and shall conform to the Indian Standard IS 13779 and IEC 62052-11, IEC 62053-21.
