DHT-208 Transformer Comprehensive Characteristics Test Console

Application:

DHT-208 transformer comprehensive characteristics test console conform to the state standard GB/T4776, GB/T5169, GB/4285.It is mainly used for load and no-load characteristics testing of power transformer, distribution transformer, also can do  power frequency voltage withstand and double frequency inductance, partial discharge tests. The measuring parts of this device is controlled by high performance single clip microcomputer, no-load and load test data are sampled by it to avoid the error caused by voltmeter, ammeter, watt meter separately reading and manual calculation in traditional test methods.

Features:

◆Large screen backlight LCD display, operation and display are clear classified, easy to operate.

◆Can do DC resistance test of 50kVA to 100000kVA power transformer, ratio group test, no-load loss test, on load loss test, AC withstand voltage test, inductance withstand voltage test .

◆Voltage, current digital display meter or pointer meter can be read directly, loss, ratio, DC resistance test results can be print and download.

◆Withstand voltage test over-current, alarm with sound and light, timing.

Specification:
