Transformer Winding Resistance Meters
RMO TT Series
-
The Tap Changer Analyzer & Winding Ohmmeter of the RMO-TT series is designed for winding resistance measurement of inductive objects, and for a tap changer analysis. The RMO-TT series is based on the state of the art technology, using the most advanced switch mode technology available today. The RMO-TT instruments are accurate (0,1%), powerful (up to 100 A) and still portable. The Instruments generate a true DC ripple free current with automatically regulated measurement and discharging circuit. RMO-TT instruments can perform a simple, quick and reliable transformer on-load tap changer condition assessment. This series of instruments enable measurements of a winding resistance in every tap position, current ripple values (percentage of a current drop during a tap change) and transition times during the tap changes. Problems with a connection, contacts, and selector/diverter switch operation (tap change with interruption) can be detected with these measurements.

Insulation Tester
-
Shenzhen Graigar Technology Co.,Ltd.
Testing the integrity of insulation requires measuring its resistance to current flow across it. A high level of resistance means that very little current is escaping through the insulation. Conversely, a low level of resistance indicates a significant amount of current may be leaking through and along the insulation.

Clamp-On Open-Loop DC MicroAmmeter & Insulation Fault Detector
-
The Clamp-On Open-Loop DC MicroAmmeter & Insulation Fault Detector is a precision tool designed for detecting leakage currents in insulation systems. Featuring high sensitivity, this advanced microammeter measures direct currents as low as 1 microampere (uA) and operates within a measurement range of 10 milliampere (mA) to 10 amperes (A). Utilizing a clamp-on method with a toroidal ferro-magnetic core featuring an air gap, the device integrates AMR sensors from a differential Hall magnetometer for accurate readings. Its design is particularly suitable for large hydro generator stator windings but is also effective in various electrical applications.The device's functionality is significantly enhanced by its use of two micro-ammeters equipped with advanced signal conditioning units and a demagnetization circuit, ensuring precise data acquisition. The accompanying LabVIEW software facilitates real-time monitoring and visualization of data, allowing operators to effectively track leakage currents and identify faults within insulation systems. The dual clamp-on setup enables simultaneous measurements, providing immediate insight into potential defects without the need for cutting conductors or removing insulation, thus ensuring operator safety and system integrity.

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.
