Used to test the breakdown voltage performance under room temperature of enamelled wires;
insulation films; insulation sleeving.
Three-gears voltage: 1KV, 2.5KV & 15KV/20KV, rise speeds are available & adjustable for each gear:20V/s, 100V/s and 500V/s, with error being ±10%;
Available to complete breakdown or withstand voltage test for samples. Breakdown voltage and withstand voltage time would be automatically saved for future query;
all operations would be automatically completed;
Touch screen control, automatic setting of pressure boost speed, storage test results;
During sample breakdown, breakdown voltage indication value would be automatically locked, no flashing, and the test result is distinct and relatively clear;
Test door is provided with safety interlocking device, compliant with relevant regulations on high voltage testing equipment.
Working Principle
This tester uses AC high voltage method to measure the breakdown voltage or withstand voltage value of the sample.According to the selected test voltage, the tester adds a certain boost rate output AC voltage to the sample at both ends.Once the sample breakdown or high voltage loop reaches the set threshold current, automatically cut off the high voltage, the tester emits an alarm sound, the screen displays the breakdown voltage value and records the current testing data, the voltage drops automatically, and automatically switches to the next test.
