Electricity Meter
Energy costs are increasing worldwide providing an impetus to greater energy efficiency. For users to benefit from this increased efficiency, an accurate and reliable measurement of consumed energy is necessary. The mechanical electricity meter is being replaced by electronic smart electricity meters with remote load monitoring. Because energy meters are installed in the power distribution network, they are subjected to transients, impulse and damped oscillatory wave (DOW) testing.
EMC PARTNER offers extensive test solutions from one hand to conduct all conducted immunity impulse and insulation tests.

The EMC tests are conducted according to IEC 62053-41 for meters with voltage up to 1500 V DC and currents up to 125A.
-
SMART ELECTRICITY METERS
SMART Meters are a.c./d.c. Meters or direct current meters used in smart grids and smart homes with the capability of communication and data transmission via Ethernet, WLAN, PLC or M-BUS. EMC offers in addition the Impulse Generators and power CDNs also Data CDNs for up to 8 lines and speeds up to 1Gbps.
Applications
The IEC 602555-26 divides the electromagnetic environment into severe (zone A) and typical (zone B), whereas IEC 61000-6-5 divides the installation environment into 4 zones from inside to outside EMC protected area. EMC PARTNER offers EMC test equipment for both zones to conduct all impulse, transients and power fail tests, including EFT up to 4kV, Surge up to 4kV, Damped oscillatory waves up to 2kV as well as Dips/interrupts and insulation test up to 8kV.
