Elspec LTD products

The G5 Phasor Measurement Unit (PMU) by Elspec is designed to enhance the monitoring and analysis of power systems by delivering high-resolution synchrophasors using its advanced PQZIP technology. This unit supports dynamic monitoring with its capability to measure synchrophasors at an exceptionally high resolution. It complies with the most updated IEEE C37.118-2011 and IEC/IEEE 60255-118-1-2018 standards, guaranteeing accuracy and reliability in synchrophasor measurements. The G5PMU is equipped to manage two independent synchrophasor data streams with differing report rates, performance classes, or data types simultaneously, thereby optimizing utility operations and communications. It features a groundbreaking data compression algorithm, yielding a compression ratio of 1000:1 by extending synchrophasor data to non-fundamental frequencies, which allows for continuous waveform recording at high sampling rates. This functionality significantly reduces storage requirements, enabling the device to record comprehensive electrical waveforms for extended periods.
