Measurement methods for 20KV high-voltage current

Thread Content

Chengneng ES1000 high-voltage clamp ammeter, with a clip diameter of 50mm, a measurement range of 0.1mA–1200A, and an extendable insulating rod with a total length of 4 meters. It features convenience, light weight, and other advantages. ES1000 is a method used for measuring transformer current. I. Test item (transformer incoming current) http://m.znele.com/uploads/allimg/151208/1-15120QA3441A.JPG
II. Take out the ES1000 high and low voltage clamp ammeter from the bag http://m.znele.com/uploads/allimg/151208/1-15120QA355337.JPG http://m.znele.com/uploads/allimg/151208/1-15120QA40B92.JPG
III. Turn on the device by pressing the red POWER button http://m.znele.com/uploads/allimg/151208/1-15120QA4153A.JPG
IV. Connect the 60KV telescopic insulating rod http://m.znele.com/uploads/allimg/151208/1-15120QA425344.JPG
V. Press the PEAK button; a clip-shaped symbol will appear below the numerical value, and the PEAK light will turn on http://m.znele.com/uploads/allimg/151208/1-15120QA43SO.JPG
VI. Locate the transformer’s incoming cable terminal and insert it directly. http://m.znele.com/uploads/allimg/151208/1-15120QA505137.JPG VII. After staying for five or six seconds, remove the pliers; at that point, the current value will be displayed At this time, the current is 2.820A. http://m.znele.com/uploads/allimg/151208/1-15120QAF6133.JPG 8. Rotate the retractable insulating rod, press the PEAK button to exit PEAK measurement mode, and press the POWER button to shut down the device. http://m.znele.com/uploads/allimg/151208/1-15120QAH52D.JPG 9. Instruments; insulating rods are fitted with cloth bags, and the testing is complete. http://m.znele.com/uploads/allimg/151208/1-15120QAIR07.JPG This is the method of using the ES1000 high and low voltage clamp ammeter to measure the current in transformers
