Why is Power Quality Monitoring Essential?

Power Quality Monitoring offers numerous benefits, including performance improvement and better quality output. A PQM system collects, analyzes, and transforms raw energy data into valuable information. For a typical monitoring setup, you measure voltage and electric current, and in some cases, ground quality when dispersed loads or harmonics are involved. Power quality monitoring can greatly assist in energy management, preventative maintenance, and quality control in manufacturing plants, saving costs in the long term. Many modern telecommunications and computer systems don't use PQM, making them vulnerable to power quality issues. By understanding the consequences of power fluctuations, you understand why power quality monitoring is crucial.

Power outages can lead to up to 40% of business downtime. Modern power plants employ digital error recorders, smart relays, and voltage recorders to monitor power. Consumers, such as buildings and factories, use power quality meters from reputable manufacturers to prevent equipment damage and fire risks.

How is Power Quality Determined?

Individual Waveform Capture allows engineers to monitor changing electrical waveforms to root out mechanical failures before they occur. Using the Acuvim IIW, these variations can be isolated, recorded, and visualized graphically.

Harmonic Distortion

Monitoring Power Quality enables the analysis of non-linear loads that impact electrical frequencies, causing issues such as misfiring, overheating, and voltage spikes. MachineSense power quality meters provide detailed harmonic measurement.

Sag & Swell Monitoring

Voltage sags and swells are short-term decreases or increases in voltage. They can affect a wide range of gear from PLCs to controllers. Often blamed on utility companies, these events usually originate within the site or building due to grounding, bonding, or shared power supplies.

Frequency Variations

Deviations in electrical frequency can disrupt logic systems and machinery operating speeds. MachineSense Power Quality Meters effectively monitor these frequency variations.

Power Factor

Power Factor measures the efficiency of electricity usage. Low power factor, often called “dirty power,” can lead to inefficiencies. MachineSense meters allow users to monitor and track this ratio over time.

Recommended Implementation

An effective Power Quality Audit using MachineSense systems ensures comprehensive measurement. These meters, readable remotely via proprietary cloud-based software and apps, can be installed permanently for proactive power quality management.

Power Quality Analysis & Application of Power Analyzer Meter

1. Why is power quality analysis important?

Electrical power drives nearly every machinery globally. Just as pure food is essential for human health, machines require clean power for optimal performance and longevity. Therefore, high-quality power is absolutely essential for efficient operation in factories and buildings. According to the IEEE 1159 standard, clean power is defined by specific limits on voltage/current conditions, grounding, and harmonics. Power distribution companies maintain these standards up to the transformers, but inside factories and buildings, power quality often degrades. This degradation can result from uneven single-phase load tapping from three-phase lines, DC loads like LEDs, UPS, and chargers. Poor power quality not only shortens machine lifespan but also poses significant fire safety risks.

2. What are some of the best applications of power quality meters?

Power Quality Meters serve various applications, such as:

  • Ensuring compliance with IEEE 1159 power standards
  • Monitoring predictive health of motors, heaters, drives using advanced algorithms
  • Comparing energy usage between different machines within a factory
  • Calculating machine utilization and productivity
  • Measuring energy usage per unit of productivity
  • Estimating electricity costs accurately based on time-of-use
  • Capturing electrical events in detail for analysis

3. How does a power quality meter work?

Power Quality Analyzers comprise one hardware and four software components:

  • The hardware captures voltage and current data of a machine or electrical line, supporting up to 6.6 kV and 0-4000A range.
  • Sensor system software extracts power quality information (harmonics, over-voltage, RMS) in real-time.
  • Power quality metadata is then analyzed for insights, which are stored in a database for six months.
  • Visualization software displays the analytics; one version for plant engineers and another for expert electrical engineers.

4. What are the different power quality issues that electricians/building managers should be aware of and be concerned about?

The IEEE 1159 standard outlines various power quality issues that should be monitored. Though there are about 37 different types, a few commonly occur frequently:

  • Current harmonics are generated by non-linear loads like DC loads (e.g., battery chargers, LEDs). They can heat up motor coils and cause frequent failures.
  • Poor grounding/earthing is essential for electronics to work properly. Unwanted radio frequencies and lightning need to be safely passed to the ground.
  • Surge events, caused by inrush currents, can damage machine controllers and electronics.
  • Voltage and Current imbalances in three-phase AC lines can be dangerous. High neutral currents, often caused by uneven load distribution, can lead to electrical fires.

5. What are the safety concerns for poor power quality?

Poor power quality may lead to electrical fires. In regions with a neutral wire, high neutral currents from harmonics and imbalance can cause fires. Motor coils may burn due to high harmonics, and poor grounding during lightning events can be hazardous.

6. What kind of equipment will get damaged due to poor power quality?

Most equipment, except old-style tungsten lamps, are susceptible to damage from poor power quality. Motors, pumps, compressors, fans, MRI machines, CT scans, robotics, servers, and HVAC systems are particularly vulnerable.

7. What standards to follow to mitigate current harmonics and other power quality issues?

IEEE 1159 is the widely followed global standard for power quality, with the latest version being IEEE 1159-2019. More details are available at https://standards.ieee.org/standard/1159-2019.html

8. Why Power Quality Problems are increasing over the last couple of years?

The rise in power quality problems can be attributed to several factors, including energy efficiency measures generating more harmonics, the growth of microgrids and renewable energy sources, and an increase in non-linear loads like mobile chargers and EV chargers.

The total annual loss to the United States GDP due to these issues exceeds $45.7 billion. However, power quality problems often go unnoticed until they result in machine breakdowns or electrical fires, signaling the urgency for timely monitoring and intervention.

5 Reasons to Monitor Power Consumption

Monitoring energy consumption is vital for efficient facility management and informed decision-making.

Why use a power logger to monitor energy consumption?

  • Understand your existing electrical panel's capacity
  • Troubleshoot circuit breaker issues
  • Identify and manage energy costs
  • Reduce energy waste

Prepare for a load study using the Fluke 1746 Power Logger.

1. Plant safety

Electricians often need to conduct a load study before adding new electrical loads, meeting the requirements from electrical inspectors, engineers, or customers. A load study involves documenting existing load levels to ensure safety and regulatory compliance, helping avoid potential electrical hazards from overloading.

2. Manage energy costs and realize savings opportunities

Many companies lack detailed knowledge about their energy costs beyond the monthly bills. By logging power use at key points within a facility, companies can identify energy waste and uncover opportunities for savings through operational changes.

3. Accuracy of electrical bill

In large facilities, sub-metering inaccuracies can raise billing questions. Comparing sub-meter readings with data from a portable energy logger ensures accurate tenant billing and reveals any metering issues needing investigation.

4. Rebates and financial incentives

Utility companies offer incentives for reducing energy use, often requiring proof of savings. Conducting pre- and post-retrofit load studies helps document energy efficiency improvements, qualifying for financial incentives.

5. Troubleshooting power quality issues

Data logging is essential for diagnosing intermittent power quality problems. An energy logger can continuously monitor loads and help identify the root cause of issues like random circuit breaker trips, which may not occur during technician oversight.
