Technical Recommendations for Choosing Zinc Oxide Surge Arresters Testing Equipment

Voltage Range Matching:

Select testing devices that match the rated voltage range of the arresters. For example, a 10kV arrester requires a high-voltage DC generator that can reach the required test levels safely and accurately.

Online Monitoring Capabilities:

Consider a digital online monitoring system for continuous tracking of leakage current, as it provides real-time data that can be helpful for preventative maintenance. This feature is especially useful for high-voltage systems in power plants and substations.

Automated Data Logging and Analysis:

Equipment with automated logging and data analysis tools can streamline testing, particularly for ongoing monitoring. Digital testers with data storage and analysis capabilities help simplify the diagnostic process and improve reliability in reporting results.

Safety Features:

High-voltage testing equipment should have comprehensive safety features, including interlocks, grounding connections, and overload protection to safeguard operators and equipment during high-voltage testing procedures.

Environmental Suitability:

Equipment that can operate reliably in varying environmental conditions is crucial. Choose devices with robust insulation, temperature resistance, and weatherproofing for outdoor testing or in substations.
