ON-LINE DETECTION AND MEASUREMENT SYSTEM FOR GASES IN OIL-FILLED ELECTRICAL EQUIPMENT

摘要

A system for on-line detection and measurement of evolved gases and/ or composite hydrocarbons in the oil filled equipments wherein the gases coming out of the top cover plate are detected by a sensing device provided with a gas trapping device and permeable membrane for stopping the flow of oil particles present in the evolved gases. The sensing device is provided with an amplifier and a programmable device for analysing, reporting and corrective actions.
