Power Quality Meters & Analyzers

A-Rent’s power quality meter rental solutions help verify performance, identify inefficiencies, and diagnose electrical problems in complex systems. Each power quality analyzer rental is fully tested, calibrated, and delivered with current probes, leads, and accessories for field deployment.

Our inventory includes three-phase power analyzers, data logging instruments, and portable power quality meters suited for commissioning, maintenance, or compliance testing. Whether you’re monitoring harmonics, tracking voltage events, or validating system performance, A-Rent provides the right tools and expert support to keep your testing accurate and efficient.

Power Quality Tester FAQs

1. What parameters can A-Rent’s power quality analyzers measure?

Our analyzers record a wide set of data points, including voltage, current, power factor, frequency, harmonics, flicker, and transient disturbances. Many models also support event capture for sags, swells, and inrush current for diagnosing intermittent or load-related issues.

2. How long can power quality meters log data during a rental period?

Logging duration depends on sampling frequency and memory capacity. Most analyzers can record continuously for several weeks to months. A-Rent can help configure your power quality meter or logger with appropriate interval settings based on your testing goals.

3. What are the current limits?

Power quality analyzers and loggers use a wide variety of current probe and current transformers (CT) accessories to measure current. A-Rent stocks fixed clamp type and flexible rope type CTs ranging from 1A to 10,000A. A-Rent will consultatively help customers select the CT that matches their application’s physical and current range requirements. Using the CT with the best matched range to the application enables the highest reading accuracy.

4. What are the voltage limits?

Power quality analyzers and loggers typically have a 1000V direct input limit. A-Rent also offers various voltage probe and potential transformer (PT) accessory options to step down voltage into the instrument’s measurement range.

5. Can I measure both AC and DC power?

Yes, power quality analyzers and loggers can be equipped with CTs that are appropriate to either AC or DC power. For instance, on an uninterruptible power supply (UPS), the meter can use a single DC current clamp to measure battery output and then AC rope CTs to measure the three phases of power output from the inverter.

6. How do I prepare reports after the monitoring period?

Each of our power quality analyzers and loggers has a software solution to review, analyze and report the recorded data. For instance, Fluke’s Energy Analyze Plus software works with the data files from both the 1777 and 1738 to prepare complete reports. A-Rent offers optional reporting support from our engineering team to assist rental customers with data reporting.

7. Are the analyzers suitable for generator or UPS testing during commissioning?

Yes. Power quality analyzers can be connected to generator outputs, UPS systems, and switchgear to validate voltage regulation, frequency stability, and power factor performance under load transitions.

8. Are the analyzers calibrated?

Yes. A-Rent performs a NIST-traceable calibration annually on each analyzer. These calibration certificates are delivered with the rental. A-Rent also functionally tests every meter after every rental to confirm continued proper functionality of every analyzer and current probe.
