Product Introduction
Digital double clamp Phase voltammeter is a high-precision low-price hand-held double-channel input measurement instrument designed for voltage current and Phase measurement on site.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�° to obtain better visual effects.
Digital double clamp Phase voltammeter enclosure USES engineering insulation materials another rubber vibration protection sleeve safe and reliable.

Product Introduction
SF6 switch is a widely used high voltage electrical appliance in the power system. SF6 gas density relay is an important element used to monitor the variation of SF6 gas density in the SF6 switch body during operation. Its performance directly affects the operation safety of SF6 switch.Due to the infrequent operation of SF6 gas density relay in the field it is often found that the operation is not flexible and the contact contact is not good after a period of time and some of the temperature compensation performance of the density relay becomes worse. When the ambient temperature changes suddenly the SF6 density relay often misoperates.Therefore DL/T596-2005 "precautionary test regulations for power equipment" stipulates that each SF6 switch user should verify SF6 gas density relay regularly.From the perspective of actual operation it is necessary to carry out regular calibration of SF6 density relay and pressure gauge in field operation.
