I. Introduction
DF***0 Double Clamp Digital Phase Meter is special designed for voltage, current and phase tests, it is in high-precision, low price, portable hand-held, dual-channel 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 by slip core current transformer. When measuring the phase between U1 and U2, the two circuit loop are completely isolated, so the possible misconnection 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 *5mm, and can be freely rotated approximately *0 °, which helps to obtain the best visual effects.
The shell of the device is made of engineering insulating material, together with a rubbermade anti-vibration protection kits for safety and reliability.
II. Features & Functions
1. Withstand Voltage
Parts between voltage terminal and meter shell, parts between the iron core of the clamp-current transformer and secondary windings can stand ***0V/*0Hz. Parts between the two voltage terminals can stand Sinusoidal AC Voltage **0V/*0Hz for 1min when testing.
2. Insulation Resistance
Between meter circuit and meter shell, between the two voltage terminals:≥*0MΩ.
