  • ETCR Ground Resistance Tester Field Test
    Sep 04, 2020

    On September 3, 2020, the company was invited by the Hunan Provincial Power Supply Bureau to conduct the ETCR2000+ clamp grounding resistance tester transformer field test in Zhuzhou. Hunan Zhuzhou transformer test field application case sharing: When the transformer has repeated grounding, we can directly use the ETCR2000+ clamp grounding resistance tester to clamp the flat steel grounding down-conductor for measurement. The jaw size of the ETCR2000+ clamp grounding resistance tester is 65mm×32mm, the jaw  is large, which is very suitable for the flat steel grounding downconductor of the transformer. In the field test of the transformer, we can also short the two ground electrodes to test the connection between the ground electrodes and the ground grid. The smaller the value displayed on the screen, the better the connection. As can be seen from the figure, the measured value at that time was 0.027 Ω, which proved that the grounding electrode was well connected to the grounding grid. In the same grounding electrode, due to the large electric field interference of the transformer, the accuracy will be affected, so it is recommended to select the end away from the transformer for measurement.

  • How to set the current gear of ETCR8600B
    Aug 15, 2021

    How to set the current gear of ETCR8600B ETCR8600B contains 15 gear current values, but how does ETCR8600B set the current gear? Function rotary switch 1. V~ gear: This symbol is the AC voltage test gear, this gear can measure AC voltage below 600V; 2. ×1/2 gear : This gear indicates that the current displayed in the setting window is ×1/2, which is also half of the current displayed in the window; 3. ×1 gear : This gear represents the ×1 of the current displayed in the setting window, which is the same as the current displayed in the window; 4. ×2 gear : This gear represents the ×2 of the current displayed in the setting window, which is twice the current displayed in the window; 5. Auto : This gear indicates automatic mode. In automatic mode, the meter automatically outputs from low current to high current in sequence until an action occurs. Current Setting Set default value : 10mA / 20mA / 30mA / 100mA / 300mA / 500mA Corresponding Gear Value Current setting 10mA 20mA 30mA 100mA 300mA 500mA X1/2 gear mode 5mA 10mA 15mA 50mA 150mA 250mA X1 gear mode 10mA 20mA 30mA 100mA 300mA 500mA X2 gear mode 20mA 40mA 60mA 200mA 600mA 1000mA ETCR8600 Leakage Protector Tester is designed to test the line AC voltage, leakage initiating current, residual non-operating current and leakage initiating separation time of various leakage protectors online, the test current from 5~1000mA with 16 grade (5、10、15、20、30、40、50、60、100、150、200、250、300、500、600、1000mA), range of the leakage initiating separation time is 0~999ms.The required output current value can be set according to the table
