The phase Voltammeter is another portable, handheld, multi-functional instrument meticulously developed by our company specifically for on-site testing. It is intelligent, accurate, stable, energy-saving, and safe. Its attractive design, lightweight construction, and easy operation make it a highly cost-effective electrical inspection and auditing device. The instrument can easily measure the phase between UU, II, and UI on-site, and can also indirectly measure the power factor and power of a circuit, determine the phase sequence of inductive and capacitive circuits and three-phase voltages, detect the transformer wiring group, test secondary circuits and bus differential protection systems, read the phase relationship between different groups of CTs in differential protection, and check the correctness of electricity meter wiring. It is suitable for power, petrochemical, metallurgical, railway, meteorological, industrial and mining enterprises, research institutions, and metrology departments. It is an indispensable testing tool, especially for departments such as electricity auditing, power supply stations, metering, dispatching, and relay protection.
