- Testing services
At SRESTA, we offer a wide range of high-precision electrical testing services to ensure the integrity, safety, and performance of your power systems. Our expert engineers and certified technicians utilize advanced diagnostic equipment to detect faults, verify functionality, and ensure your equipment operates reliably under real-world conditions
Diagnostics & Analysis services include:
Infrared Thermographic Analysis of SWGRs (Switchgears)
This is where our infrared camera comes into play to do a non-contact scrutiny to switchgear and control panels to reveal abnormal temperature rises. In this manner, loose connections or overloads will be indicated with the presence of hot spots. Its early detection saves equipment failure and fire threats.
What we do:
We inspect switchgear panels using Infrared cameras to help you identify temperature irregularities.
Hot spots are formed due to loose connections, overloading, or components deterioration which can be tracked via thermal imaging.
Mapping the temperature reading data and comparing it with the tolerating range.
Produce thermal images for a better visual guidance.
Based on the severity, immediate or planned corrective actions are recommended.
Transformer & Motor Tripping Analysis
We look into the cause of excessive tripping of Transformer and Motors such as overloading, Insulation failure or Internal Faults Testing and analysis of historical data help us to pinpoint the root cause. Finally we suggest corrective Actions based on the result proposed measures are reliable and will correct the fault ensuring the stable operation thus minimizing power production losses.
What we do:
Collect historical tripping logs, fault records & relay data
Perform Insulation and Winding resistance Testing
Check for Overloads, Phase Imbalance, Thermal Stress.
Detect Mechanical Issues like Vibration, Mis-Aligned.
Root cause analysis report along with mitigation steps.
Root Cause Fault Analysis
We analyze relay records, fault histories, and system behavior. This gives us great insights and we recommend design improvements to avoid recurrence. Knowing the real cause helps in identifying when targeted solutions are best. more vital for critical infrastructure and high value assets.
What we do:
Review system protection settings, relay coordination, and event logs.
Analyze waveform captures and fault signatures.
Identify equipment or human errors contributing to the fault.
Trace the fault path and point of initiation.
Recommend design or operational changes to prevent recurrence.
Why it matters:
Finding the root cause of a failure is the only way to prevent repeat incidents and it supports in issues related to safety, system improvement, even cost control. Root cause analysis makes the system more resilient for the longer term.
Condition Monitoring & Predictive Diagnostics
The ability to predict potential failures before they occur based on logged data for critical parameters has led to the introduction of ‘Real-time’ monitoring which can be done on the web. We are tracking parameters like Vibration, Load conditions, Insulation values and temperature Predictive diagnostics allows scheduled maintenance instead of costly downtime: Over time, we’ve found this data-driven strategy improves performance from both an asset management and systems standpoint.
What we do:
Live condition monitoring of critical electrical parameters such as temperature, vibration, insulation condition.
Use data loggers and sensors for real-time health monitoring of assets.
Discover trends by analyzing data collected so far and prepare for faults.
Schedule maintenance based on condition not just calendar time.
Connect review results to asset management systems.
