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.

Eddy Current Probes and Drivers
-
Proximity sensors work on the eddy current principle. A proximity system consists of an eddy current probe, extension cable and driver. A high-frequency RF signal is generated by the driver, sent through the extension and probe cables and radiated from the probe tip. The tip consists of a precision wound copper coil inside a chemical and temperature resistant PEEK case.

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.

IEC Standard Burden Sets (Current)
IEC Burden Sets
-
Testing and calibrating current transformers often requires standard burdens of reliable accuracy and stability, and burdens that are immune to stray fields and harmonics. These burden sets have been carefully designed to meet these requirements. They also provide the standard burdens required for the testing of current transformers for metering service, and for the testing (within the current rating provided by the sets) of current transformers for relaying applications, all as called for by IEC (International Electrotechnical Commission) Publication 185: 1987.

Logger Version 2-D Electro-Magnetic Current Meter for Deep Ocean
INFINITY-Deep AEMD-USB
-
INFINITY-Deep is an autonomously deployable data logger for current speed measurements in the deep oceans. The currents in the deep oceans are very weak. It is too hard to accurately measure the deep water currents by some ADVs (Acoustic Doppler Velocimeters) that detect the Doppler-effect by scatter with the suspended particles in the water, because the concentration is very low. INFINITY-Deep measures 2-D current data through a magnetic field according to Faraday's law. Therefore, even if the suspended particles do not exist around the sensor, it can provide the accurate current data. The depth rating is 6,000m. Compared to INFINITY-EM, the instrument has a depth and a tilt sensors to monitor mooring status. Also, the battery capacity doubles for long-term current velocity measurements.
