How often must OHE be tested at a minimum?

The minimum required frequency for testing Overhead Electrical (OHE) systems is every four years. This guideline is established to ensure that the systems remain safe and reliable for use, as they are subject to various environmental and operational stresses that can affect their integrity over time. Testing every four years helps identify any potential issues or degradation that might compromise safety or performance, allowing for timely maintenance or upgrades.

This interval strikes a balance between ensuring safety, managing operational costs, and allowing sufficient time for thorough inspections and maintenance procedures. Adhering to this schedule is crucial for compliance with industry standards and regulations, ultimately safeguarding both personnel and infrastructure involved in electrical operations.
