產(chǎn)品簡介

 

南澳電氣NASGQ數(shù)字雙鉗相位伏安表是專為現(xiàn)場測量電壓、電流及相位而設(shè)計的一種、位、手持式、雙通道輸入測量儀表。NASGQ數(shù)字雙鉗相位伏安表可以很方便地在現(xiàn)場測量U-U、I-I及U-I之間的相位，判別感性、容性電路及三相電壓的相序，檢測變壓器的接線組別，測試二次回路和母差保護系統(tǒng)，讀出差動保護各組CT之間的相位關(guān)系，檢查電度表的接線正確與否等。采用鉗形電流互感器轉(zhuǎn)換方式輸入被測電流，因而測量時無需斷開被測線路。測量U1-U2之間相位時，兩輸入回路完全緣隔離，因此完全避免了可能出現(xiàn)的誤接線造成的被測線路短路、以致燒毀測量儀表。顯示器采用了高反差液晶顯示屏，字高達25mm，屏幕角度可自由轉(zhuǎn)換約70°，以獲得視覺效果。

南澳電氣NASGQ數(shù)字雙鉗相位伏安表外殼采用工程緣材料，另配橡皮防振保護套，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
