Connecting the control unit (it is the supplementary equipment of test transformer, detailed see the explaining book) with work frequency 220V (above 10KVA with 380V), adjusting 0-220V/380V voltage input to HZJ (HZJZ) test transformer primary winding through autotransformer. According to the principle of electromagnetic influence, the secondary (high voltage) winding may gain the same multiple voltage value than the primary winding with the circle rated that is the high frequency voltage of work frequency.
This series product divides into three kinds: the alternating current is named YDJ, the alternating and direct current is named as HZJZ, meanwhile, may connecting HZJ, HZJZ with 200V switch to form series excitation transformer. IV.Technical Parameters 1. Technical parameters of HZJ series alternating current test transformers.

transformer, that’s to say, U(sum) = u1 + u2 + u3 , at the same time, the capacity relationship is S(sum)=s3×3. HZJZ will form the direct current series excitation test transformer, but we need to add 2 2 u silicon stack into the test transformer which is the highest frequency voltage after exchange series excitation.
4. Figure 4 Panel of main control box The operation of the insulation test with HZJ series HIPOT tester is as follow: 1) Please make grounding connection for sample object, HV transformer and main control box first 2) Please discharge the sample object if the sample object is a capacitive equipment.

panel the tester with enable the high voltage output unit. 8) If the regulator is not at zero position when you press down the close button the high voltage output unit would not be enabled. There is a zero position indication lighter on the panel of the main control box.
HZTC HV Hipot Control Unit I.Outline HZTC series control station is a complete set of equipment of high voltage test transformer, it and the test transformer carry out resistance pressure and leakage test. This product is in according with electric industrial standard DL/T848.2-2004. II.Main Characteristics This series product has characteristics, such as beautiful appearance, small volume, light weight, simply operation and conveniently maintenance.

VI.Manual Explanation 1.As the table shows, please connect the control station with the test transformer, also please do not forget to connect with the floor line. After careful examination, you can make electricity go through it. 2.When the electricity goes through, please turn the voltage adjustor to Null, Zero Switch turns on and the signal turns on too(which indicate that the output of the voltage adjustor is Zero).
VIII.Supplementary Explanation HZTC series control station is another set of equipment of light test transformer, it has characteristics, perfect capacity, beautify appearance, small volume, light weight, beside, also has the function of switch on and timing, which manual explanation is same as TC control station.
