SMV, SMP and SMPQ
SMPQCompact Power Quality Analyzers

Those devices are a class S power monitoring devices according to the international standard IEC 61000-4-30, ed. 2. The more advanced SMPQ can also evaluate and archive power quality data according to EN 50160 standard. An important part of this compact platform is an embedded four quadrant electricity meter. Devices offer wide variety of input-output and communication options. By default every device has an USB connector, optionally also RS232, RS485and Ethernet can be used. For more complex application where interactions with other devices is desirable the outputs can be flexibly programmed to relay or pulse outputs of various quantities. A temperature or another analog quantity can be measured from external input.

Standard Measurement Principles

* evaluation of electrical parameters in energy distribution systems or electrical installations
* in compliance with IEC EN 61000-4-30 class S
* fast and continuous measurement cycle (10 periods/~200 ms, gap-less)
* selection of aggregation intervals from 200 ms second up to 2 hours
* active and reactive electricity meter according to EN 62053-21, EN 62053-23
* data flagging concept that eliminates double evaluation of critical events
* digital flicker meter (IEC 61000-4-15)
* up to 40th harmonic and inter-harmonic components (IEC 61000-4-7)
