Safe Timing Measurements on Circuit Breakers Using Grounding on Both Sides
August 13, 2026
The regular testing of medium-voltage (MV) and high-voltage (HV) switchgear is vital for ensuring the reliability, safety, and longevity of electrical equipment and power systems. By identifying potential issues early, testing helps prevent costly downtime, accidents, and regulatory non-compliance.
Regular switchgear testing offers numerous benefits, including enhanced safety, improved reliability, compliance with industry standards, and cost savings, by identifying and addressing potential issues early on, testing helps prevent accidents, equipment damage, and costly downtime, ultimately leading to a safer and more efficient power system.
To help you assess the condition of your medium-voltage and high-voltage switchgear, we have created two new guides with an overview of potential failures and their causes, the recommended tests you can perform to detect these failures early, and which of our testing solutions to use when performing the variety of tests. The importance of each test is explained as well a description of how it is performed. Examples of test set ups and collected data are clearly presented.
