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.

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 Megger Transformer Ohmmeter (MTO) 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.

Quasi Square Wave Constant Voltage Transformers
-
Osborne Quasi Square Wave Constant Voltage Transformers are used to regulate output voltages for applications that have varying input voltages. When used with a rectifier conversion circuit, these units provide an elegant design approach to voltage regulation. Osborne achieves this innovative approach by partnering the constant voltage transformer with an auxiliary resonant capacitor winding. The result is a unique (though time honored) technology that offers reliability, performance, and cost advantages over other styles of voltage regulation.
