BS 5797 describes two procedures each using different apparatus to measure the tendency of insulating liquids to evolve or absorb gas when subjected, in cells having specific geometries, to electrical stress of sufficient intensity to cause an electric discharge through a gas phase in which a gas-oil interface is located.
The methods described in BS 5797 are suitable for purchase specifications, general selection of insulating liquids, product development and quality assurance.
BS 5797 on measurement of gassing of insulation liquids for:
Insulating liquid under electrical stress, ionization process, certain space geometry may either absorb gas or evolve gas. This process of gassing of the insulating liquid can be harmful to the components as it is in direct contact to them. BS 5797 provides with two test methods to measure this phenomenon of gassing to help you assess the quality of insulating liquids.
BS 5797 provides us best practice guidelines to:
BS 5797 can help user to select, inspect and maintain insulating liquids and ensure increased safety of appliances and equipment.
