The PM7500 Power Quality and Energy Monitor<\/strong>, an upgraded replacement of the PM7503<\/strong>, is a panel mounted<\/strong> variant of our top of the range\u00a0PM7000 Power Quality Analyser<\/a>. As with the PM7000 and PM7000FLM, as well as recording numerous power quality parameters, the PM7500, with our Enhanced Harmonics upgrade, is able to simultaneously record\u00a0individual Harmonics to the<\/strong>\u00a0100th on 3 Voltage and 3 Current channels<\/strong>, and to the 50th on the remining 2 channels, as well as the\u00a0Interharmonic and Interharmonic Sub groups to the 100th<\/strong>\u00a0as required by\u00a0ENA Recommendation G5\/5<\/strong>.<\/p>\n

The PM7500 also has\u00a0Dual Frequency\u00a0<\/strong>measurement capability, measuring\u00a0frequency to 0.001Hz\u00a0<\/strong>resolution on V4 as an independent fast frequency option with an accuracy of 0.002Hz and noise typically less than 0.001 Hz RMS. This fast frequency measurement is being used to fulfil the\u00a0National Grid Dynamic Containment\u00a0<\/strong>requirement of providing ongoing, time-synchronised, gapless data packets, over TCP-IP, of the power and high resolution frequency measurements. These values are required hourly by National Grid to ensure the\u00a0Dynamic Containment<\/a>\u00a0provider is capable of responding as per their Dynamic Containment agreement. Read more about our Dynamic Containment offering\u00a0here<\/a>.<\/p>\n

The PM7500 records events, trends and transients with min\/max logging. As standard, it can also record >500 channels simultaneously and has automatic sag\/swell monitoring down to single cycle on 32 channels using our unique recording regime\u00a0Single Cycle Adaptive Store<\/a>. As well as measuring flicker and other parameters, the standard unit measures and records harmonics up to the 50th order. As explained above, with our Enhanced Harmonics upgrade, the user can record individual current and voltage harmonics, interharmonics and Interharmonic Subgroups to the 100th simultaneously.<\/p>\n

The PM7500 has waveform capture at 384 samples\/cycle at 50Hz (19.2kHz) and Ethernet, USB and Bluetooth communication. It is also compatible with Nortech iHost and can be rack-mounted if required.<\/p>\n
