Product Description
Phase Comparator (Phasing Tester) is a specialized instrument used in power systems to detect and confirm whether the phase relationship between two independent power sources (or circuits) is synchronized. Essential for operations like equipment maintenance, new line commissioning, or dual-source grid connection in high/low voltage lines and substations, it measures and compares the phase angle (phase difference) and phase sequence. This ensures both sides are in strict phase synchronization (near 0°difference) before connection, preventing dangerous short-circuit currents, protecting personnel, equipment, and the grid from accidents. Simply put, it verifies if "the electrical steps on both sides are aligned".
