Phase voltammeter is a high-precision, low-price, hand-held, two-channel input measurement instrument designed for voltage, current and Phase measurement in the field.Using this meter, the phase between u-u, i-i and u-i can be easily measured in the field, the phase sequence of sensitive and capacitive circuits and three-phase voltage can be distinguished, the wiring group of transformers can be detected, the secondary circuit and bus differential protection system can be tested, the phase relationship between CT of each differential protection group can be read out, and the wiring of the electricity meter can be checked.The tongs current transformer is used to input the measured current, so there is no need to disconnect the measured line.When measuring the phase between u1-u2, the two input circuits are completely insulated and isolated, so it completely avoids the possible short-circuit of the measured circuit caused by wrong wiring, and thus burns out the measuring instrument.The display screen USES high-contrast Liquid crystal display with words up to 25mm and The screen Angle can be freely converted to about 70° for best visual effect.
Phase voltammeter shell USES engineering insulation materials, another rubber vibration protection sleeve, safe and reliable.
