First, the main function

HGY-type volt-ampere characteristics, variable ratio, polarity tester is designed specifically for the relay protection professional test current transformer volt-ampere characteristics, variable ratio test and polarity discrimination and design, but also for the transformer polarity discrimination test, is a Cost-effective, relatively high multi-function test equipment.
The instrument uses high-efficiency low-power materials and special winding of the booster, the microprocessor for data collection, analysis and storage, built-in micro-printer can print test data and curves, measured CT ratio, you can automatically calculate the ratio . One person can handle all the test work. The machine has a light weight, carry, easy to operate. Its unique performance, is currently rare equipment.
Second, the technical parameters
⒈ input voltage: AC 220V or 380V, 50HZ, automatically identify the input voltage.
⒉ working environment temperature: 0 ~ 40 ℃.
⒊ input voltage: input AC 220V, the output 0-500V.
Input input 380V, the output 0-1000.
Current: maximum instantaneous current, measured when the ratio of 600A.
Input input 220V, the output 0-400A.
Input input 380V, the output 0-600A.
The volt-ampere characteristic test is 15A.
⒋ digital voltmeter measurement range: 0-9999V; resolution: 0.1V.
For current display: 0-9.9A; Resolution: 0.1mA.
⒌ digital ammeter measurement range: 0 ~ 3000A; resolution: 0.01A.
⒍ error: 1 ≤ 1%, U ≤ 1%.
⒎ test CT ratio, you can automatically calculate the ratio, and print data and calculate the results.
When measuring volt-ampere characteristics, store and print 20 sets of current voltage and volt-ampere characteristics.
