InsulGard

Protective relays and predictive devices

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.

Overview Specifications Resources Support

Protect your investment

Equipment life extension

Maximise your uptime

Reduce scheduled maintenance

Mitigate your risk

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.

Intuitive user experience

InsulGard reduces the level of expertise required to analyse partial discharge data, with user-friendly software. The software allows for extensive data analysis from simple automated reporting to in-depth analysis by experts.
