DC System Grounding Fault Tester Electrical Test Equipment
Product Description:
HZJD-612 DC grounding fault tester is suitable for any voltage level DC system, equipped with high precision detection clamp meter, greatly improve the detection range and anti interference ability via the efficient processing of many kinds of signals.
Product Features:
◆ Easy to operate, turn on the power switch can be used directly.
◆ More applicable voltage level, DC system 220V,110V,48V,24V.
◆ Wide applicable range, apply to any type of electric plant, substation, coal mine, chemical plant ect..
◆ Portable, signal receiver comes with batteries, does not need external power, convenient to carry with.
◆ Find the grounding point with DC system power on, do not effect the system working.
◆ Strong anti-interference ability, overcome the effect of system distributed capacitance.
