NMi has added a new option to its range of multi-faceted services. For some time now, we can test Performance Measuring and Monitoring Devices, in short PMD’s.
A PMD is a multifunctional instrument that can measure multiple quantities, such as energy, voltage, current, frequency, power factor, harmonics, flicker etcetera. It can determine the most important system parameters of a network. Lately there is a great demand for testing and certification of this type of devices, e.g. for applications in datacenters where data for multiple customers is stored. The PMD’s are used there to measure their consumption.
NMi offers testing this type of meters against IEC 61557-12 which is a specific IEC standard for PMD’s. We have an ISO 17025 accreditation for this activity. This means that there are new possibilities for PMD manufacturers to have their instruments certified!
