3-phase Automatic Ratio Tester - NDB ART-3D successfully repaired and tested by PT. Dynamics Circuit Indonesia

The ART-3D series are precision instruments, designed to measure turn ratios, phase displacements, excitation currents of single phase and three phase power, distribution and instrument transformers in conformity to the IEEE C57.12.90 & IEC 60076.

The instrument’s rugged design is perfectly suited to tackle the most challenging field or manufacturing environments. The anti-induction mode strongly enhances the efficiency of the measurements by countering the unwanted effect of nearby induction interference. The large, high contrast, color, touch screen display offers easy menu navigation, creation of test plans and viewing of test files. The integrated LTC control terminal allows for manual or fully automatic testing sequence of On-Load Tap changers with configurable pulse duration and duty cycle. The additional tertiary winding channel of the ART-3Dx will save a great deal of time, with onetime test connections to primary, secondary and tertiary windings. One of the ART-3D’s key features is the colored and graphical way of displaying LTC test results for interpretation in seconds!

With its real 3-phase test circuit, the ART-3D can address complex ratio measurements of PhaseShifting/Regulating or irregular vector group type transformers, otherwise impossible to achieve with conventional ratio meters. Zigzag type transformers testing is very easy and will not require the installation of jumpers or the use of relay matrix circuits. The single or real 3 phase voltage output up to 275V contributes to higher magnetization currents and therefore stronger flux for better signal reflection on secondary and/or tertiary windings allowing more accurate results. The ART-3D phase displacement measurements enables for simple detection of the transformer vector group.

Megger OTS100AF - 100kV Automatic Laboratory Oil Tester successfully repaired and tested by PT. Dynamics Circuit Indonesia

The Megger OTS100AF Automatic Laboratory Insulating Oil Tester is the latest in oil test design and has replaced the Megger OTS100AF/2. This new oil test set is able to perform accurate breakdown voltage tests on mineral, ester and silicon insulating liquids. The OTS100AF offers repeatable results with lock-in precision, electrode gap adjustment. The transparent, shielded lid and large test chamber enable easy access to the test vessel. One of the fundamental tests of oil quality is the breakdown voltage test, which is a measure of the oil's ability to withstand electric stress. A low breakdown voltage can indicate the presence of contaminants such as water or conducting particles. The test voltage of the OTS 100AF is electronically controlled to the maximum of 100 kV and it has been designed to perform breakdown detection in terms of both voltage and current, which helps the range to comply with any future changes or developments in oil test standards.
