Product details
◆
This digital dual clamp phase voltmeter is a high-precision, low-cost, handheld, dual channel input measuring instrument designed specifically for on-site measurement of voltage, current, and phase. This meter can be used to more conveniently measure the phase between U-U, I-I, and U-I on site, distinguish the phase sequence of inductive and capacitive circuits and three-phase voltages, detect the wiring group of transformers, test the secondary circuit and bus differential protection system, read out the phase relationship between the CT of each differential protection group, and check the correctness of the wiring of the electricity meter. The measured current is input using a clamp current transformer conversion method, so there is no need to disconnect the measured line during measurement. When measuring the phase between U1-U2, the two input circuits are completely insulated and isolated, thus completely avoiding possible misconnections that may cause short circuits in the measured circuit and burn out the measuring instrument. The display adopts a high contrast LCD screen with a word height of up to 25mm, and the screen angle can be freely converted to about 70 ° for better visual effects.
The casing of the digital dual clamp phase volt ampere meter is made of engineering insulation material and equipped with a rubber anti vibration protective sleeve, which is safe and reliable.
Characteristics of digital dual clamp phase voltmeter:
1. Voltage resistance
Test on the ability to withstand 1000V/50Hz sine wave AC voltage between the voltage input terminal and the case, the iron core and handle of the clamp current transformer (current clamp), and the secondary winding coil, and the ability to withstand 500V/50Hz sine wave AC voltage between the two voltage input terminals for 1 minute
2. Insulation resistance
Between the digital dual clamp phase voltmeter circuit and the casing, and between the two voltage input terminals: ≥ 10MΩ
