Transformer Turn Ratio Tester

DescriptionDTBZ-2009 is an enhanced Transformer Turn Ratio Tester. It is capable to test single-phase and three-phase transformers.

The testing process is fully automatic and very quick.Another important function is automatically measuring the vector group of transformers.Operator enters the test parameters, DTBZ automatically performs the testing process: Power up the test voltage, Balance the test bridge, Take the readings and Display on the LCD screen, then Print the results on built-in printer.FeaturesLarge LCD screen, Menu operationFully automatic testing, no manual balancingTest single phase and three phase transformersAuto measure transformer vector groupAuto switch measuring rangeAuto calculate ratio errorAuto save the test dataRecall and print last 30 recordsTruly portable, Weight less than 10kgSafety FeaturesAuto cutoff test voltage after testingFuse protection for test-leads short-circuitFuse and Reset protection for reverse connection of HV side and LV sideSound an alarm when protection actSpecifications (English version available)Power Supply: AC 220V± 10%, 50Hz± 1Turn Ratio Range: 1~9999.9Vector Group Coding: Ii6/12, Dd / Dy / Yd / Yy 1~12Accuracy: 0.2 % when 1~999.9, 0.5 % when 1000~9999.9Test Voltage: AC 190VAmbient Temperature: 0~40º CAmbient Humidity: RH < 85%Dimension: 40 x 35 x 20cm, Accessory bag: 30 x 25 x 10cmWeight: 10 kg, Accessory bag: 2kg
