Air Core Test Lab Reactors

Overview

Test Laboratory Reactors are specially designed for high-voltage and high-power testing laboratories, where they operate under severe electrical and thermal conditions.

These reactors are engineered to withstand extreme electrical stresses during short-duration test cycles while providing accurate and reliable performance. Typical applications include current limiting, synthetic circuit breaker testing, capacitor testing, artificial line simulation, and other high-power laboratory testing systems. Their robust construction ensures dependable operation in demanding test environments.

  • Air core, dry-type construction
  • Optimized thermal design with low temperature rise for extended service life
  • Maintenance-free design for reliable long-term operation
  • High mechanical strength and short-circuit withstand capability
