Substation testing has traditionally required multiple instruments, numerous cables, and significant time. Today, multifunction testers such as the SUWI-120 are revolutionising this process. By combining turns ratio, contact resistance, relay timing and breaker timing tests into a single portable device, engineers can: Reduce test preparation time. Minimise human error. Maintain accurate, comprehensive records. Why it matters: Faster, more reliable testing allows maintenance teams to focus on resolving issues rather than spending hours on setup. In the long term, this approach enhances system reliability and operational efficiency. Embrace efficiency in substation testing and contact us to learn how multifunction devices can transform your maintenance programme.

High Voltage, High Responsibility: Don’t Overlook Maintenance High Voltage (HV) systems carry energy across vast distances, but even minor faults can cause major disruptions. Many companies underestimate the hidden costs of poor maintenance: Unexpected downtime: Equipment failures halt production lines. Energy inefficiency: Outdated or poorly tested systems waste electricity. Safety hazards: HV faults can endanger personnel and compromise regulatory compliance. Investing in regular testing with precise devices such as Hightest’s TRAN-203 series ensures your HV system operates safely and efficiently. Beyond mere compliance, it safeguards assets, staff, and reputation. Industry Insight:Preventive testing is far more cost-effective than corrective action. A modest investment in regular checks can prevent substantial emergency repair costs. HV system reliability begins with proactive testing. Discover more [...]
