Portable Double Clamp Volt-ampere Phase Meter

Portable double clamp volt-ampere phase meter was developed by our company and a multifunction instrument designed for field testing, with high accuracy, high stability, low power consumption, easy to use and so on. Can in was measuring loop not open of situation Xia directly measurement Exchange voltage and Exchange current, measurement two voltage between, and two current between and voltage current between of phase, also, also can indirect measuring have circuit of power factor and power, can discriminant three-phase phase sequence, transformer wiring constituency, and perceptual, and capacity sex circuit, test II times loop and mother poor protection system, read travel moving protection the Group CT Zhijian of phase relationship, check meter of wiring right or not, maintenance line equipment,.
