Interpreting DRM Results:
From Diagnosis to
Actionable Insights

The Interpreting DRM Results Training Course empowers professionals to transform raw diagnostic data into meaningful decisions that support asset reliability and operational safety. Dissipation Factor, Resistance and Megger (DRM) measurements form a key part of assessing insulation integrity and identifying early signs of deterioration in equipment such as transformers, motors and generators. Yet, the real challenge lies not in performing the test, but in understanding the deeper implications of the results.

This training course provides a structured, practical approach to analysing DRM datasets, recognising abnormal patterns and linking observations to real-world equipment conditions. Participants explore how insulation behaviours evolve over time, how contamination and moisture influence test values, and how trending these indicators can reveal early warning signs long before failures occur.

The course also highlights how DRM interpretation strengthens wider asset management goals. By aligning diagnostic findings with maintenance priorities, reliability engineers can optimise interventions, avoid unplanned downtime and extend the service life of critical equipment. With an increasing emphasis on predictive maintenance and condition-based monitoring, the ability to translate DRM outputs into actionable insights has become essential across both utility and industrial sectors.

By the end of this experience, participants will be able to confidently interpret test reports, understand the significance of each diagnostic parameter and apply analytical judgement to support safe and efficient electrical system performance.

Upon completing the Interpreting DRM Results Training Course, participants will enhance their ability to make sound diagnostic and maintenance decisions using DRM data. The course strengthens analytical capabilities, supports asset reliability objectives and improves technical understanding of insulation behaviour under different operational conditions.

Key learning outcomes include:

• Understand the operating principles behind DRM testing
• Interpret dissipation factor, resistance and insulation trends with confidence
• Identify symptoms of insulation degradation, moisture penetration and electrical defects
• Correlate DRM findings with operational behaviour, equipment age and environmental conditions
• Transform diagnostic outcomes into structured maintenance recommendations
• Integrate DRM interpretation into broader condition-monitoring frameworks
• Develop skills for using historical data to predict potential equipment failures
• Support reliability improvement initiatives through data-driven asset analysis

The course is designed for professionals responsible for equipment condition assessment, electrical asset reliability and maintenance planning. It supports individuals who need to make informed judgements based on diagnostic test data and enhances the competencies of teams involved in electrical asset care.

This Interpreting DRM Results Training Course is especially beneficial for:

• Electrical engineers and technicians involved in equipment testing
• Maintenance and reliability specialists supporting asset health programs
• Power plant and substation engineers
• Asset managers overseeing long-term performance of electrical equipment
• Condition-monitoring professionals analysing diagnostic datasets
• Supervisors responsible for maintenance planning and operational decisions

The course adopts a practical, interactive learning environment that blends diagnostic theory with real DRM examples and hands-on interpretation exercises. Participants engage in technical discussions, review case studies and practise analysing sample reports to develop confidence in identifying meaningful insights from test results.

Training delivery includes:

• Instructor-led sessions explaining DRM concepts and interpretation methods
• Guided analysis of sample test reports and trending data
• Case studies illustrating common insulation problems and corrective actions
• Group discussions for comparing diagnostic approaches
• Workshops focused on converting DRM findings into maintenance decisions
• Visual presentations supporting understanding of electrical behaviour and fault mechanisms

• AZTech Certificate of Completion for delegates who attend and complete the training course
