Capacitor banks used for reactive power compensation in substations are highly susceptible to voltage surges during switching. Without proper protection, sudden restrikes can overstress insulation and lead to equipment failure. By using a three-phase Type 2 surge arrester, transient overvoltages are safely limited, preventing damage to the capacitor sections. This ensures stable grid operation, reduces downtime caused by unexpected breakdowns, and extends the overall service life of costly power infrastructure.
In industrial environments, main distribution panels supply power to automation devices such as drives, controllers, and sensors. Surges from upstream switching or electrical faults can quickly propagate to these sensitive components, resulting in malfunctions or failures. Installing a DIN-rail mounted surge arrester directly at the main panel diverts transient energy before it spreads further. This approach not only protects critical automation systems but also simplifies maintenance thanks to the arrester’s modular, pluggable design.
Outdoor electrical systems, including water pumps, HVAC units, and cooling towers, are often exposed to voltage surges from lightning activity or grid fluctuations. These transients can damage motors and electronic control modules, causing costly downtime. Placing a robust three-phase surge arrester at the service entry point of outdoor installations ensures harmful energy is discharged before reaching sensitive components. The result is greater resilience against storms, fewer repair interventions, and increased operational continuity in demanding environments.
Wind turbines and solar inverters face frequent exposure to transient surges caused by both weather conditions and grid switching events. High-energy surges can quickly compromise inverter electronics, leading to expensive replacements. By deploying a Type 2 surge arrester at the AC output side of inverter stations, excess energy is safely redirected. Its high discharge capacity and compact form factor make it ideal for modular renewable energy systems, providing ongoing protection for inverters, transformers, and other essential components.
