Description

The conditions found in high voltage equipment can cause reactions in insulation SF6 to produce the highly corrosive agent, hydrogen fluoride (HF).

The monitoring of the HF content in SF6 is an essential element of any predictive maintenance.

SF6 breakdown products are measured extensively throughout the electricity industry as an insulating medium within high voltage equipment.

Features

• Routinely monitors SF6 Purity (0-100%), HF (0-10ppm) and SO2 (0-100ppm) using proven detection technologies.
• Ease-of-use – designed for use by plant engineers and fitters. Does not require specialist personnel, or contain any consumable chemical solutions.
• Automatic Data-logging of each individual parameter.
• Battery operated, using rechargeable Nickel Hydride battery, giving up to 8 hours operation.
