Switchgear Temperature Monitoring

Continuous real-time monitoring of switchgear temperature at critical contact points to quickly detect overload and fault conditions.

OSENSA is the industry leader in advanced fiber optic temperature monitoring specifically designed for switchgear applications. These technologies offer continuous real-time monitoring of switchgear temperature at critical contact points, enabling the quick detection of overload and fault conditions before catastrophic failures. The RS-485 Modbus communication capabilities of the system ensures seamless integration with any PLC/SCADA system and monitoring software. OSENSA's fiber optic sensors are immune to electromagnetic interference, making them ideal for mission critical switchgear applications.

Data centers and mission-critical operators demand thermal monitoring of their switchgears to ensure the reliability and safety of their operations.

Switchgears are essential components in electrical distribution systems, and undetected hot spots can lead to equipment failure, unplanned downtime, and even fire hazards. Continuous fiber optic thermal monitoring helps detect early signs of overheating, allowing for timely maintenance and preventing catastrophic failures. Additionally, maintaining optimal temperatures improves the efficiency and lifespan of the equipment, reducing operational costs and enhancing overall system performance

Fibre Optic Sensors vs Other Technologies

OSENSA’s fiber optic temperature sensors trumps the current cost-effective technologies available for high-voltage sensing applications.

Periodic IR Legacy Monitoring

Fiber optic continuous temperature sensing

Inspections

Inspections are only performed if scheduled and are often neglected allowing unwanted deterioration and defects to grow undetected.

Can detect and prevent up to 70% more failures than periodic IR inspections or top oil temperature measurement alone.

Operation

Inspections often do no coincide with peak load conditions when critical temperatures are reached

Trending of thermal activity is constantly recorded, providing important parameters for predictive diagnostics and system analytics.

Installation

Obstacles like insulation and equipment panels often prevent direct line-of-site measurement, resulting in actual hot spots being missed and under-estimating critical insulation temperatures.

Fiber optic temperature sensors are inherently safe, easy to install, and designed to reliably report temperature for the life of the equipment without need for re-calibration.

Cost Savings

IR monitoring leaves a weak audit trail for root cause analysis and may make insurance claims more difficult to support.

Continuous thermal monitoring eliminates the labor costs associated with periodic inspections, saving money in the long run.

What’s the Cost?

Maximize Your Data Center and Mission Critical facility's Efficiency with Partial Discharge & Fiber Optic Thermal Monitoring

Investing in a continuous partial discharge and fiber optic thermal monitoring system for your critical switchgear assets can yield significant returns within 6 months to 1 year. OSENSA's advance technology continuously monitors the temperature and PD events of critical components, helping to prevent equipment failures that can lead to costly downtime and repairs. Experience reduced maintenance costs and improved operational efficiency with our state-of-the-art partial discharge and fiber optic thermal monitoring solutions.

Switchgear Partial Discharge & Humidity Monitoring

Partial Discharge is a leading indicator of cable damage and insulation failure. PD magnitude is linked to the rate of deterioration.

OSENSA is the industry leader in advanced partial discharge monitoring specifically designed for switchgear applications. Ultra-high frequency (UHF) smart sensing and high-speed digital signal processing technology make it ideal for mission critical switchgear applications. OSENSA's small form-factor sensor detects partial discharge events in switchgear, bus ducts, and dry-type transformers.

Why Continuous Partial Discharge Monitoring Matters

Partial discharge (PD) is an early indicator of insulation degradation in medium and low voltage switchgear, bus ducts, and dry-type transformers.

Undetected PD activity can lead to catastrophic failures, unplanned downtime, and costly repairs. Traditional offline testing methods provide only a snapshot in time, leaving critical gaps in monitoring. Continuous partial discharge monitoring, using advanced UHF (Ultra-High Frequency) sensors, offers real-time insights into asset health, allowing for proactive maintenance and increased system reliability.

Advantages of Continuous Partial Discharge Monitoring

Unlike periodic inspections, continuous PD monitoring identifies insulation deterioration as soon as it begins. This enables maintenance teams to take corrective action before minor degradation turns into a major failure.

By detecting PD in real-time, operators can plan maintenance proactively rather than reacting to unexpected failures. This prevents costly emergency shutdowns and extends the lifespan of electrical assets.

Partial discharges are a leading cause of electrical fires and switchgear failures. The PDX-800 provides instant alarms for dangerous PD levels, ensuring personnel and equipment safety.

Unlike periodic inspections, continuous PD monitoring identifies insulation deterioration as soon as it begins. This enables maintenance teams to take corrective action before minor degradation turns into a major failure.

The PDX-800 communicates via Modbus RTU, making it easy to integrate into existing SCADA (Supervisory Control and Data Acquisition) or Building Management Systems (BMS). This allows for centralized monitoring and automated alerts.

Use PDX-800 Continuous Partial Discharge Monitoring to Stay Ahead of the Electrical D-I-P-F Curve

Electrical D-I-P-F Curve

The PDX-800 from OSENSA Innovations provides real-time, continuous PD monitoring, helping organizations detect insulation issues early and take corrective action before failures occur. By integrating UHF sensors and advanced digital processing, the PDX-800 aligns with the D-I-P-F Curve to identify, track, and mitigate insulation degradation before it reaches a critical stage.

The D-I-P-F Curve represents the four key stages of electrical insulation degradation: Degradation, Incubation, Propagation, and Failure. This model helps engineers and maintenance teams understand how insulation deteriorates over time and the critical role of partial discharge (PD) monitoring in preventing catastrophic failures.

D

Insulation begins to deteriorate due to thermal, electrical, mechanical, or environmental stresses.

I

Partial discharge activity starts but may go undetected without proper monitoring.

P

PD activity intensifies, leading to accelerated insulation wear and increased risk of failure.

F

The insulation breakdown becomes critical, causing costly unplanned outages or equipment damage.
