Eaton’s InsulGard Predictive Diagnostic solution provides continuous, non-invasive online monitoring for generators, motors, switchgear, unit substation dry-type transformers, bus duct, and cable connections. InsulGard’s constant tracking of partial discharge activity and predictive monitoring helps users to make better safety and asset management decisions. Advanced filters enhance accurate monitoring, and a user-friendly web interface provides a simple way to monitor device status.
Insulation failures cost time and money. What’s even more damaging is that insulation failures lead to arc flash events, equipment failure, unscheduled outages or, worst of all, accidents involving your personnel. Eaton’s InsulGard system predicts insulation failures before they occur.
Continuous, online monitoring.
Works with generators, motors, switchgear, unit substation dry-type transformers, bus duct, and cable connections.
