High Voltage Surge Testers
HVST
-
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. This voltage is displayed on an oscilloscope and recorded on the Pass/ Fail LED latch monitor. This voltage will be accurate despite the impedance of the winding being tested. The insulation system can be tested way above the operating voltage because of the brief duration of the applied voltage test pulse. This allows faults to be detected long before they become apparent at operating conditions.

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.

Turns Ratio Testers
TRT Advanced Series
-
TRT Advanced series is the newest DV Power solution for transformer turns ratio measurement. Besides its main application, each turns ratio tester from this series also measures transformer excitation current and phase shift. Furthermore, all models perform automatic vector group detection and magnetic balance on three-phase transformers and three-phase autotransformers. They have a built-in true three-phase power source. For that reason, they can test transformers with special configurations, such as phase-shifting, rectifier, arc-furnace, traction transformers, etc.The instruments can output test voltages from 1 V AC to 500 V AC, depending on the model. With the highest test voltage 500 V AC, TRT500 provides the most accurate turns ratio testing of power transformers used in power generation and transmission. The output test voltage of TRT500 can be boosted to 5 kV AC using the external CVT20 extension transformer. This application is specially designed for testing turns ratio of capacitive voltage transformers. The other three models, TRT400, TRT250, and TRT100 can output up to 400 V, 250 V, and 170 V respectively. The low test voltage of 1 V AC enables turns ratio verification of current transformers.TRT500 is equipped with a large 10.1” graphical touch screen display. Other models, (TRT400, TRT250, TRT100) have 7” graphical touch screen display. Besides making the interface much more user-friendly compared to older turns ratio testers, it also brings certain options that were previously available only with DV-Win software. The most important are test templates and automatic test mode. Users can simply create test templates, store them in the instrument’s memory, and load when in the field with just a few clicks.This turns ratio test set, as well as all other DV Power turns ratio testers, has a built-in tap changer control unit. It enables remote control of an on-load tap changer (OLTC) directly from the instrument. In order to make the most out of this feature, the instrument can be programmed to do everything automatically – running turns ratio tests, changing OLTC tap positions, and saving results. This option, especially in combination with test templates, significantly facilitates and shortens the turns ratio testing time. Automatic test mode minimizes human errors, which makes the measurement more reliable.

Turning Mirror
10769A
-
The 10769A is ideal for use in laser measurement and calibration applications. In the calibration of slant bed lathes, for example, the beam steering mirror deflects the beam from the laser head upward, through the interferometer, along the lathe's cross slide. One or more mirrors can also create a path from a laser head to an interferometer located in an otherwise inaccessible position, as in the case of a milling machine with a table that moves in only one axis.

Standard Helmholtz Coils
-
Helmholtz Coils are ideal for the measurement of Rare Earth (Samarium Cobalt, Neodymium) and Hard Ferrite permanent magnet materials (materials which exhibit a relative straight line demagnetization). Our standard Helmholtz Coils are for use with fluxmeters. The Helmholtz Coil measures the magnet sample as a single magnetic moment provided that the longest dimension of the magnet sample is less than one-third (1/3) the diameter of the coil system. By definition, the magnetic moment per unit volume is the intrinsic magnetization of the sample. With our calibrated Helmholtz Coil and Integrated Fluxmeter – and given the volume of the permanent magnet sample – the intrinsic open circuit operating B (Bdi) can be measured.
