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.

Real-Time Online Monitoring to Detect and Analyze Potential Partial Discharge (PD) Signals and Insulation Faults using UHF, AE, and HFCT
PDMonitor
-
Power Monitoring and Diagnostic Technology Ltd.
The PDMonitor, which utilizes Ultra High Frequency (UHF), Acoustic Emission (AE) and High Frequency Current Transformer (HFCT) sensors and is designed to conduct real time online monitoring to detect and analyze potential Partial Discharge (PD) signals and insulation faults before they lead to breakdown or catastrophic failure in power assets. The system provides the developing trend of the PD, when occurring, as alarms in real time, thus helping to predict the insulation degradation status of the asset, prevent sudden accidents, and provide an effective database for Condition-Based Maintenance (CBM) of power assets.

Partial Discharge Testing Equipment
AR700
-
PD Defect Location in High-Voltage Equipment Insulation by Acoustic Sensors To act on deteriorating insulation the source of PD must be known.The insulation defects produce partial discharges, which emits electrical impulses, radiation of electromagnetic waves as well as acoustic signals.The AR700 measures acoustic signals with multiple sensors spread over the transformer. Then the software determines the failure location using the time difference of all incoming signals. Finally, these coordinates are shown in a 3D model of the transformer. AR700 device is used for measuring of acoustic signals on the external surfaces of gas-insulated breakers and substations, power transformers and other tank high-voltage equipment. The acoustic signals are caused by partial discharges in the insulation, which is the sigh of the defects.The advantage of “AR700” device is the quick installation of the acoustic PD sensors on the external surface of high-voltage equipment tank. The sensors have magnetic holder that is why there is no need to de-energize the equipment for the sensors installation. “AR700” device has 4 syn-chronic channels for acoustic signal measurement. This gives the possibility not only to find the defects in the insulation, but also to locate them. The location function of the “AR700”device is unique for acoustic devices.
