DC Bias Current Power Supply
TH1775
-
Shenzhen Chuangxin Instruments Co., Ltd.
TH1775 is a DC Bias Current Source (or DC Magnetization Current Source) used for inductance measurement of inductors and transformer windings with DC bias current. Except for constant current output, low additional error and wide frequency response range are important for bias current inductance measurement. High frequency LCR meter could be used, when the frequency response range is wide enough. MPU controlled auto current balance technology is adopted to realize AC+DC current overlap and constant current output from 0 to ±20A. Two TH1775 can be paralleled to supply a maximum current up to 40A.TH1775 permits high frequency measurement up to 1 MHz and can be directly controlled by TH2816A, TH2817A, TH2818 and TH2819. TH1773/TH1775 with its low additional error, wide frequency response range and sweep output function is widely used in DC biased inductance measurement. TH1775 also provides a perfect solution for magnetic material analysis.

Transformer Turns Ratio Testers
-
Transformer turns ratio testers from TRT series are DV Power instruments mainly designed for the measurement of power transformer turns ratio. Also, they measure transformer excitation current and phase shift. Special tests, such as automatic vector group detection and magnetic balance, can be performed on three-phase transformers and three-phase autotransformers.All models, except TRT03 series, have a built-in true three-phase power source, which is necessary for testing turns ratio of transformers with special configurations, such as phase-shifting, rectifier, arc-furnace, traction transformers, etc.DV Power turns ratio testers can output various test voltages for different applications. From the extremely low test voltage of 1 V AC that enables turns ratio verification of the majority of current transformers, up to the highest test voltage of 500 V AC that provides the most accurate turns ratio testing of power transformers used in power generation and transmission. By using the external booster, test voltage increases up to 5 kV AC in order to successfully test capacitive voltage transformers.All DV Power turns ratio testers have a built-in tap changer control unit. Because of that, it is possible to control the on-load tap changer (OLTC) directly from the device. In order to make the most out of this feature, the instrument and included DV-Win software can be programmed to do everything automatically – running turns ratio tests, changing OLTC tap positions, and saving results. This option significantly facilitates and shortens the turns ratio testing time.TRT turns ratio testers use the same set of cables as three-phase winding ohmmeter & tap changer analyzers from the TWA series. Consequently, it enables one-time cable setup for performing eight tests:turns ratioexcitation currentphase anglemagnetic balancevector group detectionwinding resistanceon-load tap changer DVtestand demagnetization.

High Voltage Surge Current Monitors
HVSCM
-
Designed to be used with the Model HVST High Voltage Surge tester. The Surge Current Monitor allows simultaneously surge testing 20 units. The Surge Current Monitor monitors the current going through each unit under test at the time of the surge. If a unit under test breaks down or leaks, the Surge Current Monitor will identify the bad unit by lighting the corresponding LED. The most important features of the surge tester are its ability to test the entire winding insulation system. A high voltage surge generates turn to turn, coil to coil, and phase to phase voltage stress, as well as ground insulation stress. When used as a dielectric test, accurate voltage readings are essential. The HV Surge Tester monitors the voltage directly across the winding under test. In production testing we expect that most of the time the devices will pass. In the event that one should fail, the failed device would be removed and then all the parts would have ot undergo another surge test. Since most devices pass most of the time, simultaneous surge testing can be a real time saver.
