NZR, energy measurement, electricity meter services

Services: electricity meters
We can support you with specialist who have a lot of experiences concerning electricity meters. We can provide services as e.g. installation and de-installation of meters, random tests, maintenance services, calibrations and diagnostic findings.

Random tests
The validity of the calibration of the meters is temporally limited according to the legal defaults. The validity of the calibrations can be prolonged by doing random tests, so that the meters may be installed until the time when the next random test should take place, i.e. you can save the change of the meter and the purchase of a new one can be delayed

These are the most important criteria for a successful random test:

  • The complete file maintenance of the meters concerning calibration terms and installation place
  • The competent context of the meters concerning manufacturer, type and year of manufacture
  • A proper declaration and accomplishment of the random test at the gaging office
  • The accurate handling of the testing sets
  • If you have any request you can rely on the long lasting experience of the team of NZR

Rotation (Installation and De-Installation of the meter)
If the validity of the calibration is discontinued and no random tests have been made or the meter does not pass the test, all meters have to be changed. The whole accomplishment of the rotation is routine work for the team of NZR:

  • Preliminary information to the customers by using the list of changes
  • Pick up of the meters which need to be installed at the municipal utility or indeed of the meter by NZR
  • Professional change of the meter
  • Documentation of the change of the meter
  • Maintenance (see below) and calibration (see below) of the changed meters respectively purchase or scrapping
  • Return delivery of the dismantled meters

The mechanical electricity meters are very rugged and content only a few wear parts. Therefore these meters can be suited for reconditioned refurbishment. The maintenance department of NZR has a large spare part stock, which warrants the maintenance and overhauling of different types of meters of all established manufacturers.

Your meters will be handled according to the following characteristics:

  • Pickup of the meter which should be maintained
  • Maintenance according to the guideline of VDEW for the proper overhauling of electricity meters
  • Adjustment of the meters
  • Special tasks according to the orders as e.g.
  • Fix of the notification of the owner, also barcode with additional separation labels for the internal documentation
  • Changeover of voltage (230V)
  • Null position of the rollers of the meter
  • Back fitting of meters as e.g. LZ-96 back fitting from rate 2 to rate 1
  • Creation of the delivery note with all relevant data concerning the meter, also in an electronically form if desired
  • Delivery of the meter which has been maintained.
  • Calibration (also known as certification in former times)

All measurement instruments which are used for the instruction of electric energy or electric capacity need to be calibrated, if they are related to business or kept ready for usage. This concerns not only electricity meters of the energy industry but also those ones which are used in-between, below, camping ,etc. between two parties for value (e.g. hirer and landlord) The calibration of the meters takes place either at the offices of calibration of the federal states or in the legal admitted test centers.

NZR possess the sponsorship of three own legal admitted test centers for energy:

  • legal admitted test center EG 14 in Bad Laer (Niedersachsen)
  • legal admitted test center EP 22 in Lübtheen/Schwerin (Mecklenburg-Vorpommern)
  • legal admitted test center EF 6 in Hirschhorn/Heidelberg (Hessen)

According to the laws of calibration the tree legal admitted test centers calibrate new and obsoleted electricity meters until 150 Ampere and 500 voltage as well as current transformers until 1200 ampere. For the accomplishment we use only test control units which are latest models, full automatically or have computer programmed controllers All gained data will be acquired and will be put into the archives under consideration of the legal allegation.

Test of diagnostic findings
The test verifies the correctness of an calibrated meter. This is a mandatory regulation, which needs to be documented in an inspection report of a legal admitted test center. If the customer has got his invoice according to the display of the meter and he has doubt about the correctness of the meter, he has the right to apply for a diagnostic finding. It will then be checked if the adherence of the error margins can be guaranteed This mostly very sensitive matter can be addressed faithfully as a third party to NZR.
