Open Circuit Locator
A994
-
The A994 is an open circuit locator for electric and telephone cables wind on the reel; it gives the position of the fault from the inside or outside end of the cable, in percentage to the total cable length. The instrument measures the ratio of the capacitances of the two sections of failed conductor using two high precision i/v converters. The advantage of this method is due to the fact that the measurement error depends almost exclusively on the dimensional inhomogeneity of the cable. The A994 has the unique feature to permit the location of fault in cables with all broken wires. This instrument locates breaks in cables with a total capacity between 2 nF and 5 uF. The distance to fault is displayed on a large LCD display.

Three-Phase Transformer Winding Resistance Meters
TWA Advanced Series
-
TWA Advanced series is the latest DV Power solution for three-phase transformer winding resistance measurement and tap changer analysis. They are capable of testing six transformer windings with a single cable connection, as well as three-phase automatic transformer demagnetization. It has the option of the automated test mode, where the instrument operates the tap changer without operator input (minimizing the risk of human error) and records winding resistance results based on pre-selected stabilization criteria.The unique DVtest method of tap changer analysis 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, together with the measurement of tap changer motor current which detects 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 simultaneously on three phases. It can also be performed together with the winding resistance test in all tap positions.A unique advantage of TWA Advanced instruments 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 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.

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.

40-196-101
Fault Insertion Unit
The 40-196 is a 10 Channel 5A Fault Insertion Switch, primarily designed for the simulation of fault conditions in automotive & avionics applications involving the reliability testing of safety critical controllers. It is designed to be able to insert different fault conditions between the test fixture and the equipment under test: Open-Circuit, Short-Circuit between signal pairs, Short-Circuit between signal pairs and user applied fault conditions e.g. Power or GND. Shorting relays on each channel enable UUT signals to be subjected to external user applied fault conditions or to be shorted to the adjacent signal in the same channel. Relays in line with the signal allow open circuit conditions to be simulated on either side or both sides of a channel signal pair. The switching topology of the 40-196 allows channels to be interconnected so that complex fault insertion systems can be constructed.
