Which brand of digital double-clamp phase voltammeter is better? Preferably imported? I hope someone with knowledge can give me some advice.
The domestic technology of digital double-clamp phase voltammeters has basically passed the test, so there is no need to buy imported ones. It is recommended that you buy a phase tester from a manufacturer, because such instruments are very professional testing equipment, and after-sales service requires a certain professional technical foundation. This is very convenient.
Wuhan Edian Electric Power Test Equipment Co., Ltd. is a professional manufacturer of digital double-clamp phase voltammeters. Their products are guaranteed for three years.
Product Introduction
ED0604A digital double-clamp phase voltammeter is a high-precision, low-priced, portable and handheld type specially designed for on-site measurement of voltage, current and phase. , dual-channel input measuring instrument. This meter can be used to easily measure the phases between U-U, I-I and U-I on site, identify the phase sequence of inductive and capacitive circuits and three-phase voltages, detect the wiring groups of transformers, and test secondary circuits and bus differential protection systems. , read the phase relationship between each group of CTs in the differential protection, check whether the wiring of the watt-hour meter is correct, etc.
Product Features
◆Exquisite structure, easy to use
◆Handheld structure;
◆In the current range of 10mA-10A, There is no need to disconnect the circuit and replace the limit when measuring the phase within the voltage range of 3V-500V;
◆The display uses a high-contrast LCD screen with characters up to 25mm, and the screen angle can be freely converted by about 70° to obtain Best visual effect;
◆The switch function and layout are reasonable, and the measured voltage, current and phase can be read by turning the switch.
