Electrical issues don’t always leave obvious clues. One day your system runs perfectly — the next, you’re facing tripped breakers, overheating components, or unexplained downtime. That’s where power quality analyzers come in.
These devices go beyond basic voltage checks to reveal hidden problems in your electrical system — like harmonics, voltage sags, and transient events — that can quietly wear down equipment and waste energy. But with so many models, features, and brands available, choosing the right analyzer can feel overwhelming.
In this guide, we’ll break down what power quality analyzers do and share practical tips for selecting the right tool for your specific application — whether you’re troubleshooting a motor or monitoring an entire facility.
What Does a Power Quality Analyzer Do?
A power quality analyzer helps you measure and diagnose disturbances in your electrical system — including voltage sags, harmonics, transients, flicker, and unbalanced loads. Whether you’re troubleshooting a motor issue or verifying compliance with IEEE 519, the right analyzer gives you the data to make confident decisions.
Top Brands We Trust (and Why)
At Lakeland, we’ve worked with hundreds of customers to help solve power quality issues. Here are a few trusted brands we recommend:
-
- Dranetz – If you’re looking for advanced analytics and long-term monitoring, Dranetz delivers. The HDPQ series offers deep dive analytics, real-time waveform viewing, and flexible setup for permanent installations or temporary studies.
-
- Fluke – Known for portability and rugged reliability, Fluke’s handheld analyzers like the Fluke 1770 Series are ideal for on-the-go troubleshooting. Automatic logging and simplified setup make them perfect for field techs and facility teams.
Each brand has strengths depending on the application — so let’s talk about how to match features to your specific needs.
How to Choose the Right Power Quality Analyzer
When selecting a PQA, consider:
1. What’s your application?
Are you doing a quick check on an individual machine, or analyzing a whole facility?
-
- For basic checks: Go with a portable handheld unit (like the Fluke 1730 series).
-
- For facility-wide monitoring: Choose a more advanced model with high-speed data logging (like Dranetz HDPQ).
2. What measurements do you need?
Some analyzers only measure voltage and current, while others capture everything from harmonics to waveform distortion and energy consumption.
3. How long will you need it?
If you only need a unit for a short-term study or to confirm a fix, renting a PQA can be a smart, cost-effective choice.
4. Ease of use matters
Modern units like the Fluke 1777 have auto-setup features that reduce human error. That means less time fiddling with settings, and more time solving the problem.
