Replacing kWh meters

We are currently working together with Joulz to replace the kWh meters in Eurofiber’s street cabinets, PoP and ILA locations. The meters will be replaced by smart meters. We use our small trailers with an emergency power generator (NSA) to supply the location with power during the work. A tough job, because there are many locations throughout the Netherlands. But in this lovely weather ☀️ our engineers can work well! 💪

The preparations
Before the kWh meter at a location can be replaced, our engineer first needs to check whether the 230V backup system is functioning. The work will then be started in consultation with Eurofiber’s Network Monitoring Center (NMC):

  • The power to the UPS is disconnected. The equipment in the location will then run briefly on the batteries of the UPS.
  • The emergency power generator (NSA) will be connected and the power supply is also connected to the UPS. All B-feeds are now supplied again with voltage.
  • The site’s mains power is switched off.
  • The engineer of Joulz installs the new smart kWh meter and checks the operation of the meter.
  • After approval, the site’s mains power will be switched back on. The engineers jointly test whether the supply voltage of the grid is stable.
  • The NSA is then disconnected, so the equipment in the location will again run briefly on the batteries of the UPS.
  • The 230V power supply of the UPS is reconnected.

Completion of the work
Finally, the entire location will be checked for operation. Our engineer checks whether the power supply is restored to the switches, whether the backup system is working and whether the alarms are received and whether the cooling system is functioning. After approval from the NMC, the engineers move on to the next location!
