Stimulus Induced Fault Testing
SIFT
-
SIFT allows for the analysis of numerous stimuli to identify speed, fault, and parametric differences in silicon. The heart of the SIFT technique revolves around intentionally disturbing devices with external stimuli and comparing the test criteria to reference parts or timing/voltage sensitivities. Synchronous interfacing is possible to any tester without any wiring or program changes. The system can be based on either a motorized probe station or portable microscope stand for test head applications.

Polarity Tester
PT-1
-
International Electro-Magnetics, Inc.
The PT-1 provides a simple and easy way to determine the relative polarity of coil windings. It allows for an in-process test that takes a minimum of time to perform. By placing a coil on the platform and making connection to the start and end of a winding, a test signal is induced in the winding. The induced signal is low level and completely safe for the operator. By comparing the test signal phase of the coil under the test output, the relative polarity is indicated by the Red/Green LED. The tester operates by inducing a signal voltage in the coil under test by means of a magnetic flux field. The field is generated by a coil located in the probe base. The coil configuration is designed to provide optimum field distribution. We have also applied this basic circuit to a 5-channel scanning unit.

Three-Phase Transformer Winding Resistance Meters
TWA Standard Series
-
When it comes to winding resistance measurement on three-phase power transformers and autotransformers, TWA Standard series offers some of the most technically advanced instruments with LCD display in the market. Both models are capable of testing six transformer windings with a one-time cable connection, as well as three-phase automatic transformer demagnetization. The stored magnetic energy is safely automatically discharged at the end of the test. The built-in tap changer control unit enables automated test mode, where the instrument operates the tap changer without operator input and records winding resistance results based on pre-selected stabilization criteria. This option makes the operator’s job significantly easier.Both models can output test currents from 5 mA to 25 A DC for the purpose of winding resistance measurement. TWA40D has a special test mode for checking the synchronization of on-load tap changers with three phases simultaneously tested in parallel, in which the total test current can rise to up to 40 A DC.TWA40D has additional advantages when it comes to non-intrusive tap changer analysis. The unique DVtest method enables checking the moving contacts of on-load tap changers during the transition, measuring the transition time, detecting open circuits, and many other types of faults. It is performed with 0.1 ms sampling rate, simultaneously with the measurement of tap changer motor current which helps with the detection of motor and mechanical issues. A special proprietary algorithm is used for testing tap changers connected through a built-in series (booster) transformer. The DVtest can be performed either on one phase or on three phases simultaneously. It can also be performed as an additional test simultaneously with the winding resistance test in all tap positions.An additional unique advantage of TWA40D is the capability of simultaneously testing the winding resistance of all three phases of a three-phase transformer (connected in a YN configuration). This can significantly shorten the total testing time – for example, it enables the operator to perform 33 measurements instead of 99 on a tap changer with 33 tap positions.The test leads for TWA three-phase transformer winding ohmmeters are interchangeable with the TRT turns ratio testers, which means that both sets of tests can be performed with a single test lead connection to the power transformer terminals.

This can significantly speed up the testing– for example, it enables the operator to perform 33 measurements instead of 99 on a tap changer with 33 tap positions.TWA500 is equipped with a large 10.1” graphical touch-screen display, while TWA400 has a 7” graphical touch-screen display. Besides making the interface much more user-friendly compared to older winding ohmmeters, it also enables certain test options that were previously available only with DV-Win software. The most important among them are DVtest, tap changer motor current measurement, “Heat Run” test, test templates, and automatic test mode.

You can go up and down in voltage to select the voltage at which you want to test the insulation. Once you have selected that voltage, you need to connect the test leads to the Insulation Tester to measure. Then it measures voltage to ensure there is no voltage present on the equipment under test. If there is a voltage present, it will warn you to disconnect the circuit before proceeding. If it’s free of any voltage, then you can proceed with the testing. This ensures that no damage is done to the Insulation Tester KM 6213AIN.• One of the new innovation on this tester is also the way the new unique calibration process works. It’s fully digital, has no moving parts and does not require expensive and complicated jigs or computers systems to be calibrated. It’s cheaper to maintain than any other Digital HV Insulation tester on the market today. The KM 6213AIN is supplied standard with our Premium test Leads Kit, the AL-50.
