Asset Management Excellence Using Smart Distribution Equipment

1. Setting the Stage for Smarter Grids

A sudden equipment failure can do more than interrupt power.

• For a utility, it means regulatory pressure, increased network instability, and emergency repair costs.
• For an industrial plant, it can bring an entire production line to a halt, wasting hours and incurring millions of dollars in costs.

Behind every reliable operation are electrical assets working quietly to maintain the stability and efficiency of systems. These assets often operate in harsh environments where heat, humidity, dust, where repeated switching operations, short-circuit currents and load variations, impose constant electrical stress that gradually erodes their condition.

Therefore, in today’s world, where energy infrastructure is becoming increasingly complex with each passing day, waiting for equipment to fail is no longer an acceptable approach.

This is where UTEC steps in with its suite of asset management services. Leveraging our capabilities, utilities and industrial customers can ensure equipment reliability and performance, thereby achieving long-term operational stability.

2. Why Asset Management Is Crucial in Power Systems

At a time when the power grid is expanding and growing old simultaneously, decision-making becomes complicated and prone to errors. A continuous insight into the actual performance of the equipment is vital for optimal functioning.

2.1 The Hidden Cost of Aging Infrastructure

Since transformers, switchgear, and circuit breakers often operate beyond their designed lifespan, insulation deterioration, mechanical fatigue, and decline in performance are natural consequences. This not only increases the maintenance costs and the likelihood of unexpected outages but also creates safety concerns.

2.2 From Time-Based to Data-Driven Maintenance

As power systems become more complex and equipment ages, static, scheduled maintenance of equipment is no longer effective. Condition-based models are the need of the hour, helping teams anticipate problems and plan interventions before failures occur. This approach will help improve reliability, optimize resource allocation, and extend the equipment’s lifespan.

3. Smart Monitoring: A New Era in Grid Management

Intelligent monitoring has become a cornerstone of modern asset management, enabling continuous visibility into equipment health and performance. Through advanced sensors, IoT integration, and real-time data analytics, it allows early detection of anomalies.

Built on this foundation, UTEC is proud to offer solutions and services featuring a range of sensors that employ intelligent monitoring capabilities to continuously track key parameters, including temperature, partial discharge, contact resistance, oil condition, and other critical indicators of electrical equipment. It also logs equipment performance in real-time. This logged data enables digitalization, facilitating smart maintenance, and faster decision-making across the entire electrical infrastructure.

The illustration below provides a general overview of how the maintenance plan is implemented.

The data collected from these systems is integrated into UTEC’s asset management platform, Dynamic Rating’s LIFESTREAM, giving operators a unified view of system-wide performance.

By correlating data across multiple asset types, UTEC enables proactive actions that prevent failures, resulting in reduced downtime and extended equipment life.

3.1 Smarter Monitoring for Transformers

UTEC’s advanced monitoring solutions ensure the reliable operation of transformers across distribution networks. For example, covering aspects like On-Load Tap Changer (OLTC) operation, bushing health, and partial discharge are crucial in transformer health monitoring. UTEC’s E Series and C50 Transformer Monitors help customers achieve these capabilities.

Additionally, the condition of the transformer is continuously monitored and analyzed through the deployment of Dissolved Gas Analysis (DGA) units, oil moisture probes, and temperature sensors. This real-time data allows maintenance teams to identify emerging faults early and plan targeted interventions.

3.2 UTEC’s Approach to Switchgear Monitoring

Switchgears are critical equipment in electrical distribution networks. UTEC’s advanced monitoring solutions provide real-time visibility into the health of switchgear assets. This is achieved by deploying a combination of partial discharge sensors, thermal monitoring devices, and contact resistance trackers. UTEC enables continuous monitoring of assets, capturing early signs of wear or stress.

4. Predictive Maintenance and Lifecycle Decision-Making: From Data to Action

With the advancement of digital monitoring, the focus is shifting from fault detection to prevention. Predictive maintenance relies on analytics to predict equipment malfunction and the aging process. UTEC’s solutions transform real-time data into actionable insights, enabling operators to rectify issues before equipment fails, thereby lowering the total cost of ownership (TCO) of electrical assets.

4.1 Understanding Predictive Maintenance

Predictive maintenance relies on real-time data to analyze how the equipment behaves under varying conditions. Maintenance actions are guided by indicators such as rising temperatures, changes in vibration, or increasing gas levels.

4.2 Turning Data into Actionable Insights

Dynamic Rating’s LIFESTREAM transforms sensor streams into alerts and forecasts that prioritize interventions. For example, rising dissolved gases in a transformer or abnormal contact resistance in a breaker can trigger a maintenance task days or even weeks before the failure occurs.

4.3 Making Smarter Lifecycle Decisions

Retrofitting assets with sensors can often extend the lifespan of existing assets, and in some cases, this can be more economical than replacement. Thus, predictive data can also serve as a powerful financial tool, offering a cost-effective way to extend life.

Data can also help determine when replacement, reconditioning, or retrofitting becomes the optimal choice by identifying the point at which risk and lifecycle costs outweigh the value of continued operation.

5. Physical Upgrades in Focus: A Closer Look Through the Lens of Asset Management

Building on predictive maintenance insights, physical upgrade services translate data-driven findings into tangible improvements for assets. These upgrades address aging components and enhance overall performance, ensuring equipment remains reliable and aligned with modern operational standards.

5.1 Equipment Replacement and Retrofitting: Driving Asset Modernization

To extend the life of an asset and improve the system’s reliability, both replacement and retrofitting of equipment are key strategies for enhancing system reliability. For example, aging transformers and other critical assets often require modernization to meet current performance and safety standards. Retrofitting allows existing equipment to integrate new technologies at a lower cost than full replacement.

5.2 Beyond Maintenance: The Role of Refurbishment and Reconditioning

Delay and long lead times have become a major concern today when it comes to replacing aging transmission and distribution (T&D) equipment with new units. To ensure continuity of site operations, UTEC provides refurbishment and reconditioning services for the older equipment. The process involves component replacement or system upgrades, implemented through systematic inspections, advanced diagnostic techniques, and precision restoration methods.

UTEC’s expertise also extends to the reconditioning of transformer windings. Depending on the condition, the winding undergoes cleaning, drying, tightening, or complete rewinding to restore electrical integrity.

5.3 Transformer Oil Management: Treatment, Purification, and Quality Control

To prevent premature equipment failure and maintain the dielectric strength and thermal efficiency of transformers, UTEC offers transformer oil treatment and purification services. UTEC follows an extensive, multi-step process for oil purification, which includes,

1. Heating and pre-filtration
2. Vacuum degassing and dehydration
3. Fine Filtration and Purification
4. Regeneration

Transformer oil treatment and purification are essential physical interventions that complement digital monitoring and maintenance. The former detects anomalies in oil parameters, and the latter ensures those issues are mitigated before they escalate into costly failures.
