产品详细介绍
产品简介
NASGQ数字双钳相位伏安表是专为现场测量电压、电流及相位而设计的一种高精度、低价位、手持式、双通道输入测量仪表。NASGQ数字双钳相位伏安表可以很方便地在现场测量U-U、I-I及U-I之间的相位,判别感性、容性电路及三相电压的相序,检测变压器的接线组别,测试二次回路和母差保护系统,读出差动保护各组CT之间的相位关系,检查电度表的接线正确与否等。采用钳形电流互感器转换方式输入被测电流,因而测量时无需断开被测线路。测量U1-U2之间相位时,两输入回路完全绝缘隔离,因此完全避免了可能出现的误接线造成的被测线路短路、以致烧毁测量仪表。显示器采用了高反差液晶显示屏,字高达25mm,屏幕角度可自由转换约70°,以获得良好的视觉效果。NASGQ数字双钳相位伏安表外壳采用工程绝缘材料,另配橡皮防振保护套,安全、可靠。

Product introduction
NASGQ series Digital Display Clamp-on Phase Meter is special designed for voltage, current and phase tests, it is in high-precision, low price, portable hand-held, dual-channel input measuring. It's easy to measure the phase between U-U, I-I and U-I, identify the inductive circuit ,capacitive circuit and the phase sequence of three-phase voltage, detect the wiring group of transformer, test the secondary circuit and bus differential protection system, display the phase relationship among the CT groups of a differential protection system, and check if the wire of electric meter was correctly connected. When testing customers do not need cut off the tested current which input by slip core current transformer. When measuring the phase between U1 and U2, the two input circuit loop are completely isolated, so the possible miss connection is absolutely avoided, which may result in short circuit and may even burn the meter. The monitor of the device is high-contrast LCD screen, and the character in which could be as high as 25mm, and can be freely rotated approximately 70 °, which helps to obtain the best visual effects.
The shell of the device is made of engineering insulating material, together with a rubber–made anti-vibration protection kits for safety and reliability.
Also called name
Phase meter, clamp phase meter, digital clamp phase meter
