Product Introduction DC system grounding fault tester is a new generation of tester. It can be applied to dc systems of any voltage grade. It is equipped with high-precision detection clamp table which greatly improves the detection range and anti-interference ability through efficient processing of multiple signals. Advanced algorithm and fuzzy control theory are adopted to express the superiority degree of detected insulation branch in numerical form which fully reflects the superiority of artificial intelligence. They have accurate judgment on the location of the grounding point and can point out the location and direction of the grounding point every time. DC system grounding fault tester takes system safety as the primary premise conducts detection in a reliable low-frequency signal in strict accordance with the requirements of industry standards and carries out a large number of practical applications in the field without any impact on the system. Dc systems in power plants and substations provide power supply for control protection signals and automatic devices. The safe and continuous operation of dc systems is of great importance to ensure power supply and distribution. As the dc system is not grounded by floating system if two-point grounding occurs it may cause the above devices to misoperate and refuse to operate thus causing a major accident. Therefore when one point grounding occurs the grounding point should be accurately and quickly detected while ensuring the normal power supply of the dc system to eliminate the grounding fault so as to avoid the possible harm of two points grounding. DC system grounding fault tester is used to find the exact location of DC system grounding points of power plants and substations in the case of constant electricity. All kinds of grounding faults can be found out quickly with good accuracy. Product nickname: DC Ground Fault Tester DC System Fault Tester DC System Ground Fault Tester DC System Ground Fault Tester

At present conventional QJ44 type double-arm DC bridges are commonly used in power systems to measure contact resistance and the test current of such bridges is only mA level and it is difficult to find defects in reducing the cross-sectional area of the loop conductor. When measuring the contact resistance of the high-voltage switch conductive loop the measured value is several times larger due to the influence of the oil film and the oxide layer between the contacts and the contact resistance value cannot be truly reflected. To this end the latest Ministry of Power Standard DL/T845.4-2004 "General technical requirements for resistance measuring devices: loop resistance tester" and the new version of the verification procedures JJG1052-2009 "loop resistance tester straight resistance test procedures" made a measurement ( Isolation) The measuring current of the contact resistance of switches circuit breakers etc. is not less than DC 100A and the minimum current maintenance time is not less than 60S ensuring accurate test results. The High Precision Micro Ohmmeter operator panel is ergonomically designed to meet operational habits and uses high frequency switching power supplies and digital circuit technology for the measurement of loop resistance in switch control equipment. The test current is DC 100A and 200A recommended by national standards. The loop resistance can be directly measured under the condition of DC 100A and 200A. The test result is displayed by large-screen LCD LCD and has functions of data storage output printing time setting etc. and 50A 150A gears for users to choose; custom Test time the maximum setting time is 599S which is larger than the standard 60S; it is a very stable contact resistance tester with a resolution of 0.01�¼�© in China and its performance exceeds the imported high current micro-ohmmeter. It meets the requirements of on-site high-voltage switch maintenance of electric power and power supply departments and loop resistance test of high-voltage switch factory.

Product Introduction With the continuous update and expansion of modern technology higher requirements are put forward for the reliability of power system and high-voltage equipment. Accidents or damage of electrical equipment are usually closely related to insulation defects. Large capacity of electrical equipment high voltage structure diversification and sealing electrical equipment should be put forward a new higher requirements. With the increasing use of large-capacity equipment the insulation performance cannot be detected by ordinary megohm meter. Power test procedures for a number of power equipment such as: cable motor generator transformer transformer high voltage switch lightning arrester and other requirements to do a series of insulation performance tests the first is to do insulation resistance test. When testing the insulation resistance of large-capacity power equipment the insulation resistance value is related to the pressurizing time. The longer the pressurizing time is the higher the insulation resistance value is. This phenomenon is called insulation absorption phenomenon. In order to understand the insulation performance of the subject it is necessary to conduct the absorption ratio and polarization index test first so as to provide safety guarantee for the next leakage dielectric loss partial discharge and insulation performance test. According to the electric power standardization regulations our company specially introduces BC2010 Insulation Resistance Tester with large capacity high anti-interference and stable performance which can conduct Insulation absorption ratio and polarization index tests on electric power equipment providing accurate judgment in the early stage for series Insulation tests.
