+ At your request, RTE conducts a contradictory verification of the proper operation of your metering installations. This operation consists of a contradictory verification of the metering device of the metering installation, and, where relevant, verification of the wiring of the current transformers making up the metering installation.

  • Generators

Service description

The "contradictory verification of the metering device at the request of the customer" service is carried out in 1 or 2 phases. The 2nd phase is rarely triggered after the 1st phase, which is generally sufficient.

The first phase of the service includes:

  • The metrological verification of the main meter using an annually calibrated meter, an injection test set, cable and accessories. The meter is declared to be compliant if the measurement error values do not exceed the accepted tolerance limits;
  • Verification of the visual consistency* of the transformation values of the current limiters with the values provided by the customer and specified in the contract (CART or additional services contract).

This first phase does not require the removal of meters or the lockout of current limiters.

The second phase includes more in-depth verifications by RTE of the measurement chain, and requires lockout of the connection installation of the customer’s current limiters.

*If access permits; especially difficult access for voltage transformers
