SMART ELECTRICITY METER TESTING
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.
