Transformer Bushing Monitoring
Bushings are the most failure-prone components of a power transformer. Even a single bushing failure can quickly escalate to catastrophic transformer damage, including fires, contributing to increased asset downtime. In the majority of cases, these events are due to poorly managed bushings or to periodic testing that only alerts operators to a fault after it has occurred.
Transformer bushing monitoring provides operators and asset experts with real-time visibility through continuous measurement and analysis of bushing electrical and insulation-related parameters. Unlike traditional monitoring methods, this condition-based approach captures subtle changes in component health & performance, ensuring early fault detection and proactive maintenance.
Online transformer bushing monitoring also enables predictive intelligence, minimizing maintenance costs and downtime while maximizing transformer efficiency.
Condition-based transformer bushing monitoring employs retrofit sensors and monitors to continuously track essential indicators during normal operation. The collected data is analyzed using advanced analytics and algorithms to assess parameters like leakage current, capacitance variation, and insulation degradation.
Additionally, asset performance management systems that centralize transformer condition-monitoring data further help detect patterns, forecast failures, and provide alerts on the progression of degradation. As a result, potential risks can be addressed before they lead to failures, ensuring informed decision-making based on actual bushing conditions rather than on assumptions or asset aging alone.
Thus, transformer bushing monitoring shifts maintenance response from reactive to predictive, maximizing reliability, efficiency, and asset ROI.
Rugged Monitoring’s complete bushing monitoring systems encompass IIoT-based sensor BSENS, retrofitted at the bushing tap, to continuously capture leakage currents in real-time. Any imbalances in bushing insulation directly result in variations in leakage current, providing key outputs such as capacitance, tan delta, and partial discharge signals. This raw data is securely transmitted and digitized by our edge device, BM201, as a standalone option or R501 as a rackmount solution.
The digitized data is integrated into Rugged Monitoring’s enterprise asset performance management (APM) suite, RM EYE. By applying AI/ML algorithms, health indicators, and analytics, RM EYE empowers operators and asset experts with data-driven analytics. RM EYE’s trend analytics, fault forecasting, and contextual alerts further support predictive strategies.
Thus, RM’s end-to-end transformer bushing monitoring system is not an isolated function but contributes to an integral part of complete transformer monitoring in substations.

What are the benefits of transformer bushing failure detection in substations?
Transformers are the most critical component in substations. Early fault detection and the prevention of transformer bushing failures reduce unplanned downtime and maximize substation reliability.
How is online bushing monitoring different from periodic testing?
Unlike periodic testing, which relies on time-based maintenance, online bushing monitoring provides continuous, real-time insight into bushing failures.
Can RM’s transformer bushing monitoring be retrofitted to existing transformers?
Yes. RM’s transformer bushing monitoring solutions can be retrofitted to existing or new transformers without a complete asset shutdown, making them efficient and non-intrusive.
