JCB-2 of Transformer oil micro moisture on-line monitoring sensor

Summarize

Power transformers and reactors are valuable assets in the power industry. Real-time monitoring of trace moisture in insulating oil plays a vital role in the safe operation of these valuable assets. Because the existence of moisture will reduce the breakdown voltage of insulating oil and increase dielectric loss, accelerate the degradation and aging of polymer insulation materials, thus reducing the various properties of the insulation system. In serious cases, it will cause insulation breakdown and partial discharge, affecting the safe operation of the power system. JCB-2 adopts the world's advanced moisture and temperature detection devices, which can continuously, accurately and rapidly measure the water activity, micro-water content and temperature in oil under harsh environment.

Advantage

Continuous rapid detection of water activity (aw) in oil Accurate measurement of micro-water content (ppm) in oil Long-term stable operation in harsh environment Convenient local calibration function High oil resistance and pressure resistance Compact structure and easy integration Multi-mode signal output

Application

Electric power industry monitoring transformer and reactor insulating oil Industrial machinery monitors lubricating oil and hydraulic oil of mechanical equipment The transportation industry monitors engine oil of ships and vehicles.Technical parameter
