The Eaton Predictive Diagnostics is part of the Eaton Corporation. Eaton Predictive Diagnostics offers non – destructive testing technologies and sensors to assess the condition of the electrical insulation in medium and high voltage electrical equipment.
Valuable information about equipment condition allows optimal and timely predictive maintenance actions, to prevent insulation breakdown and equipment failure at a low cost
Science of Predictive Diagnostics
The integrity of medium and high voltage insulation systems can be assessed through Partial Discharge (PD) Analysis and Power factor (Tan Delta and Capacitance) monitoring technologies.
These predictive diagnostic technologies utilising specialized sensors and instrumentation, are used to quantitatively evaluate insulation integrity while the equipment is in operation.
This non-invasive method of evaluating equipment without a shutdown improves productivity and ensures system reliability.
Eaton’s BushingGard predictive diagnostic online monitoring technology measures the capacitance and discharge current of high voltage condensing type transformer bushings while the transformer is in operation. Non-invasive, continuous testing provides real-time problem detection to prevent crippling transformer, circuit breaker or shunt reactor bushing failure. Monitoring may be remote or on-site.
Customized bushing sensors available with appropriate lead-time.
Eaton’s InsulGard™ is a continuous, on-line, medium voltage, predictive maintenance system that has a variety of applications; including switchgear, bus duct, transformers, generators and motors. It predicts insulation failures before they occur.
How does it work?
By measuring partial discharge activity in medium voltage equipment, InsulGard™ provides intelligence about the wellness of electrical insulation, enabling better decision-making for managing electrical assets and increasing safety for plant personnel.
What is the payback?
The average cost of motors, generators and switchgear can range from $100k to many millions, and if a station is shut down, that loss can be catastrophic. In addition, buying equipment is only part of the expense of replacing it.
Protect your investment
In many circumstances, InsulGard™ can double the equipment’s life span. InsulGard™ can maximise your uptime. InsulGard™ is a more economical alternative for maintaining electrical power equipment.
Eliminate periodic scheduling of downtime to perform tests and time-based maintenance that lead to customer inconvenience.
The InsulGard™ predictive relay revolutionised predictive maintenance practices by introducing one continuous, online partial discharge (PD) monitoring system designed for the following medium voltage applications:
Continuous and eliminates the chances of failures occurring between periodic test events. Online eliminates the inaccuracies of offline tests. InsulGard™ also reduces the level of expertise required to analyse PD data with user-friendly software.
