Is it recommended to use a compressor for an air test on high-voltage gloves because it provides more pressure and faster results?

Is it recommended to use a compressor for an air test on high-voltage gloves because it provides more pressure and faster results?

• A. True
• B. False
• C. Not recommended
• D. Only under supervision

Answer: (B)

The test checks that insulating gloves hold a defined amount of pressure without leaking, so you can verify the glove’s integrity before use. A compressor isn’t the right tool for this because it delivers air at high flow and can easily push the pressure beyond the specified test level or cause sudden pressure changes. That uncontrolled over-pressurization risks damaging the glove, potentially causing a rupture. In addition, compressor systems can introduce oil, moisture, or contaminants into the glove and test setup, which can contaminate and degrade the dielectric material and lead to inaccurate results. Using a manual pump or a calibrated, low-pressure source provides steady, controllable pressure that stays within the tested rating, giving a reliable indication of whether the glove is leak-free.
