Scope

This document specifies the fire hazard test methods for materials used in dry reactors and the entire reactors, the short-circuit test for inrush current during switching on of dry reactors, and the assessment and grade requirements for the fire hazard level of materials used in dry reactors and the entire reactors. This document is applicable to dry air-core reactors, including: --- - Parallel reactors; - Series reactors, including current-limiting reactors and neutral-point grounding reactors; - Filter (tuning) reactors; - Capacitor damping reactors; - Capacitor discharge reactors; - High-voltage direct-current transmission and industrial smoothing reactors; - Bridge-arm reactors. This document is not applicable to core-equipped dry reactors, such as converter valve parallel reactors.
