Surge testing is undoubtedly the most comprehensive single test available for wound products. Its primary function is verification of insulation integrity. Designed for rapid Go/No-Go testing, the 1660 detects latent and existing insulation failures such as turn-to-turn shorts, layer-to-layer shorts, coil-to-coil shorts, winding-to-winding shorts, and phase-to-phase shorts are best detected by surge testing. Open circuit and ground detection are secondary benefits of surge testing. The verification of insulation integrity of simple coils, chokes, solenoids, transformers, stators, field coils and other wound products make the surge test a 'must' for the quality conscious manufacturer.
