InsulGard

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. 

Protect your investment
Equipment life extension
Maximize 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.

Core features

  • Continuous, online monitoring. 
  • Works with generators, motors, switchgear, unit substation dry-type transformers, bus duct, and cable connections. 
  • Advanced filters enhance accurate monitoring. 
  • Web interface provides an easy way to monitor device status. 
  • Innovative sensor technology provides best in class sensing capability. 
  • Remote monitoring service available through EESS organization (www.myinsulgard.com). 
  • Factory installed into new equipment or retrofitted into existing equipment.

Intuitive user experience

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