Phase Measurement Units (PMUs) provide a high bandwidth window into electrical grid state and dynamics going beyond the capabilities of traditional SCADA systems. microPMU&#8217;s filter and isolate the grid waveform&#8217;s fundamental component and digitize it together with a GPS-derived time reference signal; the data (in the US) is streamed to Utilities for network control and analysis using the IEEE C37.118 protocol. PMUs enable precise amplitude and differential phase measurements (based on the GPS timestamp) across long distances, for example, mapping grid instabilities at a state or national level. Powerside&#8217;s microPMU accomplishes the same mission but with yet higher resolution and phase accuracy options, which are optimized for the cross-town distances and increasing complexity of electrical distribution systems. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"535\" data-src=\"https:\/\/modomodostage.com\/_client\/PWS\/PWS101\/wp-content\/uploads\/2020\/10\/Learn-series-micropmu-1024x535.jpg\" alt=\"learn-series\" class=\"wp-image-5803 lazyload\" data-srcset=\"https:\/\/modomodostage.com\/_client\/PWS\/PWS101\/wp-content\/uploads\/2020\/10\/Learn-series-micropmu-1024x535.jpg 1024w, https:\/\/modomodostage.com\/_client\/PWS\/PWS101\/wp-content\/uploads\/2020\/10\/Learn-series-micropmu-300x157.jpg 300w, https:\/\/modomodostage.com\/_client\/PWS\/PWS101\/wp-content\/uploads\/2020\/10\/Learn-series-micropmu.jpg 1200w\" data-sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" style=\"--smush-placeholder-width: 1024px; --smush-placeholder-aspect-ratio: 1024\/535;\" \/><noscript><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"535\" src=\"https:\/\/modomodostage.com\/_client\/PWS\/PWS101\/wp-content\/uploads\/2020\/10\/Learn-series-micropmu-1024x535.jpg\" alt=\"learn-series\" class=\"wp-image-5803\" srcset=\"https:\/\/modomodostage.com\/_client\/PWS\/PWS101\/wp-content\/uploads\/2020\/10\/Learn-series-micropmu-1024x535.jpg 1024w, https:\/\/modomodostage.com\/_client\/PWS\/PWS101\/wp-content\/uploads\/2020\/10\/Learn-series-micropmu-300x157.jpg 300w, https:\/\/modomodostage.com\/_client\/PWS\/PWS101\/wp-content\/uploads\/2020\/10\/Learn-series-micropmu.jpg 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/noscript><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">PMU filter design is a tradeoff of competing parameters: measurement uncertainty and noise\/harmonic rejection generally improve with more sophisticated filters, to the detriment of data latency. Monitoring dynamic events for detection and control applications, such as micro-grid islanding detection, favors simple, fast filters, resulting in the lowest data latency. On the other hand, precise impedance-based fault location based on complex tensor mathematics benefits from the best uncertainty and higher noise rejection filters with longer latency.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Our microPMU supports multiple filter types, including standard IEEE C37.118 M and P Class filters, and includes our proprietary high-resolution mode. <\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td>\n  &nbsp;\n  <\/td><td><strong>   C37.118 M &amp; P Class Filters   <\/strong><\/td><td><strong>   High precision filter   <\/strong><\/td><\/tr><tr><td><strong>Type   <\/strong><\/td><td>Low &amp; moderate filtering   <br>Moderate noise rejection   <\/td><td>Complex filtering  <br>High noise rejection   <\/td><\/tr><tr><td><strong> Typical Applications   <\/strong><\/td><td>Islanding &amp; Transient detection  <br>ROCOF measurement   <br>High bandwidth current-flow    <\/td><td>Impedance modelling <br>Fault location   <\/td><\/tr><tr><td><strong>Typical Amplitude Resolution   <\/strong><\/td><td>+\/- 0.5 %   <\/td><td>&lt; +\/- 0.01 %   <\/td><\/tr><tr><td><strong>Typical Differential Phase Resolution   <\/strong><\/td><td> +\/- 0.5 <sup>o<\/sup>      <\/td><td>+\/- 0.001 <sup>o<\/sup>   <\/td><\/tr><tr><td><strong> Filter Latency   <\/strong><\/td><td>50 ms   <\/td><td>0.7 s   <\/td><\/tr><tr><td><strong> Streaming Rate   <\/strong><\/td><td>60 Hz   <\/td><td>120 Hz   <\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<div style=\"height:36px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">As microPMU&#8217;s are gaining adoption in distribution networks, the devices&#8217; agility to perform more than one mission is critical.
