PENTA P&B Dry Air Pump provides a portable solution for on-site testing of Gas and Oil operated Buchholz relays.
A charge of air is created in the polycarbonate cylinder by means of a foot-operated pump. The Dry Air Pump cylinder contains an indicating silica gel, which then absorbs the moisture present in the air.
The pressure of the air charge is monitored on the built-in pressure gauge. When a suitable pressure has been attained, the air charge is then quickly passed to the Buchholz via a flexible tube, by opening the ball valve fitted to the cylinder. To prevent backpressure from forcing the oil back down the flexible pipe, a non-return valve is incorporated into the unit.
The indicating silica gel is a crystalline material, which absorbs moisture readily. The properties of the crystals can easily be regenerated by heating/drying. The crystals are impregnated with Iron compounds, which give them an orange colour. Upon absorption of moisture these crystals change from their orange colour to a pale yellow and then become colourless.
When the crystals change to pale yellow they should be regenerated. This gel is not classified as dangerous.
PBwel offer a range of accessories to compliment the Buchholz range.
These include a Dry Air Pump to enable on site testing of both Trip and Alarm functions through a handy portable foot operated pump which passes air through a desiccant to ensure no moisture enters the Transformer.
PENTA is a globally recognised designer, manufacturer and supplier of temporary portable earthing, voltage detectors, Buchholz relays and electrical safety products.
With a heritage spanning over eighty years, and world-class experience in equipment designed for the safe maintenance of power systems, PENTA provides customers with high-quality service, reliable solutions and technical expertise.
