Partial Discharge Test - Solid Dielectric Module

It covers routine partial discharge testing for epoxy-encapsulated and other solid dielectric switchgear modules. The form captures module identification, test setup, environmental conditions, measured discharge levels, defect observations, and final disposition. It is designed to document evidence of voids, cracks, or insulation anomalies before they become field failures.

Use it during scheduled quality checks, incoming verification, factory acceptance testing, or periodic maintenance testing of solid dielectric modules. It is especially useful when you need a repeatable record of test conditions and readings across multiple modules. It is not a substitute for a full design qualification program or a destructive failure analysis.

A qualified electrical test technician, quality inspector, or engineer familiar with the test procedure should complete it. The reviewer should understand the equipment under test, the measurement method, and the acceptance criteria being applied. If the test involves energized work or controlled access, the responsible supervisor should verify the safety preconditions before testing begins.

This template is aligned to common electrical quality and safety practices rather than one single rule set. Depending on the site, it may support internal procedures, manufacturer test methods, and broader electrical safety expectations under OSHA general industry requirements and NFPA guidance. If your organization uses a specific acceptance standard, add it in the test standard field.

The most common issues are skipping calibration verification, failing to control background interference, and recording readings without noting the exact test point or voltage. Another frequent problem is treating a single reading as conclusive when repeat readings are unstable. This template helps prevent those gaps by forcing the operator to document conditions, method, and disposition together.

Yes. You can add your own pass/fail thresholds, voltage steps, dwell time, and measurement method to match your equipment and procedure. Many teams also add asset tags, serial numbers, manufacturer references, and defect severity ratings. The structure is flexible enough to support both shop-floor testing and field verification.

An ad hoc list often misses the context needed to interpret partial discharge results, such as ambient conditions, interference, and repeatability. This template keeps the test sequence consistent and makes it easier to compare results across modules and test dates. It also creates a cleaner record for review, corrective action, and audit follow-up.

Yes. The findings and disposition fields make it easy to route defects into corrective action, non-conformance, or maintenance follow-up workflows. Teams often link the record to asset management, quality management, or inspection logs so test results stay attached to the module history. That makes trend review and release decisions much easier.
