Industrial Electronics & Drives

Variable-speed drives and industrial power electronics — reading a trip correctly, and separating a genuine drive failure from the load, ramp, cooling or installation defect that caused it. Includes the practices that reliably destroy drives and are still found on live installations.

Scope

• ▪Drive trips and fault interpretation
• ▪DC bus over-voltage and regeneration
• ▪Thermal derating and cooling
• ▪Motor cable, screening and earth leakage
• ▪Installation defects that destroy drives
• ▪Capacitor ageing and storage
