Resist Processing Systems
The EVG100 series resist processing systems establish new standards in quality and flexibility for photoresist coating and developing. Designed to provide the widest range of process variations, the EVG100 series’ modularity offers spin and spray coating, developing, bake and chill modules to suit individual production requirements. These systems accommodate the processing of an extensive range of materials such as positive and negative resists, polyimides, double-sided coating of thin resist layers, high viscosity resists, and edge protection coatings. These systems can handle more than one substrate size, from 2" to 300 mm diameter, rectangle, square or even irregular shaped substrates, with no or very short tooling time. This allows the development of new devices or processes on an industrial level, which not only requires high flexibility but also controlled and repeatable processing. EVG has built up many years of spin and spray coating experience for demanding applications and incorporates this knowledge into the EVG100 series, where our process know-how can be leveraged to support our customers.

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.

Transformer Winding Resistance Meters
TWA Standard Series
The TWA standard series instruments are designed to measure the resistance of six coils and simultaneously analyze the three-phase tap changer on load of the primary and secondary transformer coils (provided by model TWA40). This is done in a single cable configuration, with test currents up to 40A. Each transformer configuration has a special measurement algorithm that is optimized for rapid stabilization of test results. The TWA instruments generate a true DC current without ripple. Both current injection and magnetic circuit energy discharge are automatically regulated.
