Testing Capabilities

The Doble Laboratory is fully equipped to perform a wide variety of tests on insulating materials, with more than fifty tests offered on a routine basis. All tests can be performed as received or after thermal or voltage-endurance aging, and under a variety of conditions.

• Doble is experienced in testing apparatus with different waveforms, including lightning and switching impulses, power frequency, and DC.
• We can help with specifications for compliance testing, problem detection, endurance testing, research on dielectric behavior, failure analysis, and partial discharge detection.
• We can also perform accelerated aging and thermal cycling tests on cables and life-endurance testing on stator winding coils.

All test data is entered into our custom-designed database, and reports, created in Excel, are readily transmitted electronically. They can also be supplied in TOA format. Let Doble help you customize condition assessment program to meet your needs.

Doble Laboratories testing capabilities include:

• Dissolved gas analysis
• Furanic compounds in oil
• Water-in-oil analysis
• Degree of polymerization
• Oil quality screens
• Metals-in-oil
• Polychlorinated biphenyls (PCBs)
