PDF3000 DC system ground fault tester PDF3000 DC ground fault tester is a new generation of products. It can be applied to any voltage level of the DC system, equipped with a high-precision testing clamp, through the efficient processing of multiple signal detection range and greatly improved anti-jamming capability; with a good algorithm and advanced computing fuzzy control theory will be detected degree of insulation branch representation in the form of numerical superiority out, fully embodies the advantages of artificial intelligence; to determine the location of the ground, they have a more accurate sense, each test can indicate ground position and orientation. The DC ground fault tester to system security is paramount premise, according to the highest industry standards require, reliable way to detect low-frequency signals, and in the field a lot of practical applications, without any impact on the system. DC system power plants, substations for control, protection, signal and automatic device to provide power, security, continuous operation of the DC system to ensure power generation and supply has a great importance. Because the DC system for floating system ungrounded system, if two grounding occurs, it may cause malfunction of the apparatus, refused to move, resulting in a major accident. So when a little grounding occurs, it should be accurately and rapidly detect the DC system to ensure the normal power supply, while the ground, remove the earth fault, thus avoiding potential hazards grounding points. DC system fault tester is used to find the exact location of power plants, substations DC system ground in the UPS case. Various types of ground fault, can quickly find the ground, the accuracy rate of 100%. http://www.whgdmk.com/aspcms/product/2014-4-30/134.html product nickname DC system ground fault tester, DC ground fault tester, DC system fault tester http: //www.whgdmk .com Product features an easy to use, this DC ground fault tester simply turn the power switch can be used directly, without the other two key operation, safe and reliable, this instrument without stopping the motor and all other power float on the DC system no effect 3, for more voltage DC systems 220V, 110V, 48V, 24V are available 4, wide application, any type of power plants, substations, mines, chemical plants and other electricity sector can use 5, easy to carry, the signal The receiver comes with a battery, no external power supply, you can carry anywhere to find ground 6, DC power systems continue to find ground, does not affect the system work 7, anti-interference ability of the system to overcome the impact of distributed capacitance 8, intelligent charging management, reduce charge time, longer battery life
