Eurelectric opposes proposed inclusion of instrument transformers in Europe’s MID


Brussels, Belgium — (METERING.COM) — November 10, 2009 – The Union of the Electricity Industry in Europe, EURELECTRIC, has opposed the proposed inclusion of instrument transformers in the EU Measuring Instruments Directive (MID).

The MID, which covers a wide range of apparatus including gas, water and electricity meters, is intended to harmonize requirements for placing on the market and putting into use those measuring instruments subject to legal metrology controls, so as to create a consistent internal market.

The Directive was published in April 2004 for application after 30 October 2006, with a 10 year transition period, and implementation of the new legislation into the various national statute books is currently ongoing. Meanwhile, however, the European Commission has taken a formal decision to revise the Directive.

Among the proposed changes is a review of the requirement for a utility meter to be fitted with a display, which EURELECTRIC says it supports.

EURELECTRIC also says that its metering experts suggest monitoring and reviewing the work being done by the International Organization of Legal Metrology (OIML) to revise International Recommendation IR46 relating to electricity meters and they support the development by Western European Legal Metrology Co-operation (WELMEC) of a guide for the sealing of utility meters.

However, Eurelectric says it is opposed to the inclusion of instrument transformers in the MID, because of the potential impact on costs and operational complexities for utilities, on whom the responsibility would fall for the conformity of a system comprising a meter and instrument transformer.

“EURELECTRIC does not understand why at this stage there is a wish to include instrument transformers nor from where this originates – we have now lived with the MID for some 5 years without this being an issue,” says the organization in a new report on the MID.

“EURELECTRIC opposes proposals to incorporate instrument transformers into any revision of the MID and requests that the Commission note this position and that any working and other groups involved with MID revision are made aware of it.”
