Partial Discharge

Partial discharge testing can detect issues early and prevent unplanned downtime. Partial discharge testing, as part of a routine maintenance plan, provides critical data and can detect system issues to better manage risk, prioritize equipment maintenance, and optimize budgets. HVM's team offers unparalleled expertise in PD testing, providing fast, accurate results to help you improve power system reliability and worker safety.

Transformer Services/Oil & Fluid Analysis

Fluid sampling and analysis as part of your preventive maintenance plan, can extend the life of your most valuable assets. While large power transformers are among the most reliable equipment used in electrical power systems, failures do occur. Replacing a transformer is expensive and lead times are long. Performing routine oil/fluid analysis is the most effective, cost-efficient tool used to identify problems early, maximizing the life expectancy of your critical assets while avoiding costly outages.

Infrared Services/Thermal Imaging

Infrared testing can detect trouble spots while equipment remains energized. A leading cause of electrical equipment failure is overheating caused by poor connections, overloaded circuits, failing components, or imbalanced loads. HVM's infrared and thermal imaging services will help you identify conditions that could result in a fire or electrical breakdown, allowing you to take action before damage or unplanned outages occur.
