Abstract

Abstract A device used in the determination of the quantitative composition of gases dissolved in the insulating oil of oil-insulated electrical apparatus wherein the device is capable of removing insulating oil samples and includes a pump arrangement for the extraction of the gases from the insulating oil sample by means of reduced pressure and for conveying it to an analytical section is disclosed. This device is intended to operate directly on the electrical apparatus to be investigated. This is achieved in that the device is constructed in a transportable manner and incorporates a peristaltically operating pump arrangement. This pump arrangement contains at least one peristaltic pump, whose inlet can be connected via an extraction vessel with the removal device and whose outlet can be connected optionally with the outside air or with a gas collecting vessel. The gases from the gas collecting vessel are analyzed in the analytical section.
