Electrical testing is a proactive approach to maintaining the health and integrity of electrical systems. It involves the systematic evaluation of electrical equipment, circuits, and systems to ensure they meet specified standards and operate safely and efficiently. By conducting regular electrical tests, organizations can identify potential issues before they escalate into costly failures, minimizing downtime and maximizing productivity.
