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.

Safety Test Panel for Geyser
-
Electrical Safety is the most primary and essential product conformity requirement for any product that uses electricity. The clauses of safety testing of electrical products laid by worldwide agencies such as UL, CE, BIS, etc. are stringent. The products need to pass through tests such as the high voltage test, insulation resistance test, earth bond test, leakage current test and so on. And to conform to such tests, SCR Elektroniks have developed for the testing of Geyser. In addition to the conventional safety tests, test for performance is also included.

Cable & Insulation Testers
-
A cable insulation resistance test is a test that is performed by applying 500 V or more between the conductor and ground and measuring the resulting leakage current. An insulation resistance tester is a test instrument that measures current that leaks through the insulation into ground. Insulation resistance tests can be performed with insulation multi- meters (IMMs) or megohmmeters. Insulation resistance testers are calibrated to display megohms (MΩ) of resistance. A satisfactory insulation resistance measurement should be in millions of ohms.

Transformer Resistance Testing
-
Weshine Electric Manufacturing Co., Ltd
Transformer insulation resistance deterioration is one of the most common causes of transformer failure: a failing transformer is a costly replacement in an electrical system with the potential for a long downtime. If you fail to maintain your transformer with regular insulation resistance testing (as can be carried out by the WESHINE Transformer Ohmmeter (VS-3110 series) of transformer test equipment) then it’s likely to fail before reaching its maximum operating life.

Tap Changer Analyzers & Winding Ohmmeters
-
Winding resistance test of inductive test objects, such as power transformers, is one of the most effective non-intrusive ways of checking its condition. Due to their advanced design, DV Power winding resistance meters provide high test currents (up to 100 A DC) and high accuracy (up to 0.1%) within light and portable test instruments. In addition to winding resistance measurement, it is also possible to perform simple, quick and reliable transformer on-load tap changer condition assessment by recording the test current during tap changer operation, also known as DVtest. Because of that, problems with a tap changer connection, contacts, and switching procedure can be detected.DV Power winding ohmmeters consist of single-phase RMO-T and three-phase TWA series. Models from the TWA series are designed for six-winding resistance measurement of power and distribution transformers, with only one single-step cable setup. As a result of reducing the total test time, it enables significant saving of time and money.Typical application areas of these instruments are high-voltage substations and industrial environments. They are intended to measure the resistance of:Transformer windingsOn-load tap changersGeneratorsElectrical motorsHigh-current bus bar jointsCable splicesWelding joints
