Key Electrical Parameters and Monitoring

Voltage, Current, and Load

You need to monitor voltage, current, and load to keep your power system healthy. These parameters show how much electricity your equipment uses and if it operates within safe limits. Continuous monitoring gives you real-time data, which helps you spot problems before they cause failures. In telecom and data center environments, you rely on this data to maintain operational efficiency.

You should pay attention to these critical aspects:

Power quality: Check for balanced phases and avoid excessive neutral current. This prevents energy waste.
Power factor: Watch for low power factor, as it signals inefficiency and can lead to extra costs.
Capacity management: Analyze load trends to prevent overloads and ensure efficient power distribution.

You can use the following table to understand common threshold values for voltage:

Parameter	Threshold Value
Voltage sag threshold	Below 90% of nominal
Voltage swell threshold	Above 110% of nominal
SEMI F47 voltage sag immunity	50% voltage for up to 200ms
	70% voltage for up to 500ms
	80% voltage for up to 1 second

If you see values outside these ranges, your equipment may face stress or damage. The Smart Power Distribution Unit helps you track these numbers and respond quickly.

Temperature and Insulation Resistance

You must also monitor temperature and insulation resistance. High temperatures can speed up the aging of your equipment. The hottest points, called hot spots, are especially important. If the temperature rises just 6°C above the rated level, the insulation can age twice as fast. This weakens your equipment and increases the risk of electrical breakdown.

Sustained high temperatures can also cause oil inside transformers to break down. This process produces gases that signal thermal faults. By watching for abnormal temperature changes, you can catch early signs of aging and prevent failures.

Insulation resistance tells you how well your equipment resists electrical leakage. Low resistance means your system is at risk for short circuits or breakdowns. Regular checks help you keep your power system safe and reliable.

Data Collection and Processing Methods

Sensor Integration in ESTEL Smart PDUs

You depend on accurate data to keep your equipment running smoothly. ESTEL integrates several sensors into each unit to monitor key electrical and environmental parameters. These sensors collect real-time information, which helps you track the health of your system. You can see the types of sensors and their functions in the table below:

Sensor Type	Function
Voltage Sensor	Monitors voltage levels in real time.
Current Sensor	Monitors current levels in real time.
Temperature Sensor	Monitors temperature levels in real time.
Environmental Sensor	Monitors environmental conditions.

You use voltage and current sensors to check if your equipment operates within safe limits. Temperature sensors alert you when heat levels rise, which signals possible aging or faults. Environmental sensors detect changes in humidity or air quality, helping you maintain optimal conditions.

Data Transmission and Preprocessing

You receive data from these sensors through secure transmission channels. The Smart Power Distribution Unit sends information to a central monitoring system. You access this data remotely, which allows you to respond quickly to any issues.

Before you analyze the data, the system preprocesses it. This step removes noise and filters out irrelevant readings. You get clean, reliable information that supports accurate health assessments. The unit uses intelligent algorithms to organize and summarize the data. You see trends and patterns that help you make informed decisions about maintenance and equipment replacement.

Tip: You can set alerts for abnormal readings. This feature lets you act fast and prevent downtime.

You rely on these methods to keep your power infrastructure safe and efficient.

Quantitative Scoring and Health Index

Scoring Models and Algorithms

You use quantitative scoring models to turn electrical data into clear health scores. These models help you understand the condition of your equipment and make decisions based on facts. You see several types of scoring models in the industry. Each model uses a different approach to handle complex data and uncertainty.

Fuzzy comprehensive assessment lets you deal with uncertain or incomplete information. You get a score that reflects real-world conditions.
Combined weighting model uses multiple factors and assigns importance to each. You see a balanced health score.
Neural network model learns from historical data. You get predictions about equipment health based on patterns.
Bayesian network model helps you reason with uncertain data. You see how different factors affect the health score.

You also find other methods that support health assessment. The table below shows some popular models and their descriptions:

Model Type	Description
Hybrid Information-Based Method	Utilizes both quantitative data and qualitative knowledge for a balanced evaluation of equipment health.
Fuzzy Rule	Incorporates fuzzy logic to handle uncertainty in health assessments.
Analytic Hierarchy Process (AHP)	Organizes and analyzes complex decisions using mathematics and psychology.
Evidence Theory	Provides a framework for reasoning with uncertain information.
Belief Rule Base	Combines rules and beliefs to assess health states effectively.

You select a model based on your needs and the complexity of your system. You rely on these models to turn sensor readings from your Smart Power Distribution Unit into actionable health scores.

Tip: You can improve accuracy by combining several models. This approach gives you a more reliable health index.

Mapping Scores to Aging Degree

You use the health score to estimate the aging degree of your equipment. The score ranges from 0 to 100. Higher scores mean your equipment is healthy. Lower scores signal aging or potential faults.

You follow a simple mapping process:

Collect real-time data from sensors.
Process the data using your chosen scoring model.
Generate a health score.
Compare the score to aging thresholds.

You see the mapping in action with the following example:

Health Score	Aging Degree	Recommended Action
90-100	New or Excellent	Routine monitoring
70-89	Slightly Aged	Schedule preventive checks
50-69	Moderately Aged	Plan maintenance soon
30-49	Heavily Aged	Immediate maintenance
0-29	Critical	Replace equipment

You use this mapping to decide when to perform maintenance or replace equipment. You avoid unexpected failures and extend the life of your power system. You rely on the Smart Power Distribution Unit to provide accurate scores and support your decisions.

Note: You can set custom thresholds based on your environment and risk tolerance.

You gain confidence in your maintenance strategy. You keep your telecom and data center equipment running smoothly by using quantitative scoring and health index mapping.

Maintenance and Replacement Strategies

You use health scores to guide your maintenance and replacement decisions. When the system detects a drop in the health index, you can schedule preventive checks or plan immediate repairs. This approach supports predictive maintenance, which relies on real-time data instead of fixed schedules.

You can compare maintenance strategies using the table below:

Factor	Preventive Maintenance	Predictive Maintenance
Cost of Inspections	Recurring, regardless of need	Condition-based, fewer over time
Repair Costs	Moderate, can include unneeded repairs	Lower, due to early detection
Unplanned Downtime	Still occurs between intervals	Significantly reduced
Labor & Overtime	Often required for shutdowns	Reduced through advanced scheduling
Part Replacements	Based on age, not wear	Based on actual degradation
ROI	Neutral to moderate	High, often achieved within months

You can avoid unnecessary costs and reduce unplanned downtime. Research shows that predictive maintenance delivers 8-12% cost savings over preventive approaches. You also improve risk assessment by using an AI-driven risk matrix, which helps you identify future risks and optimize your maintenance strategy.
