Cartoli’s selection of power analyzers, power quality analyzers, power loggers, and power quality loggers is built for electricians, energy managers, maintenance teams, and engineers who need reliable insight into electrical performance. Some jobs require high-accuracy power measurement to quantify load, demand, and efficiency. Others require power quality diagnostics to capture disturbances, identify root causes, and document conditions over time.
Power analyzers are precision instruments used to measure electrical power and energy accurately and produce replicable results. These tools focus on what a system consumes and how it performs electrically under load. Power analyzers commonly measure voltage, current, frequency, real power (kW), apparent power (kVA), reactive power (kVAR), power factor, and energy (kWh), and are frequently used for benchmarking, verifying improvements, comparing loads before and after changes, and documenting electrical performance for audits or internal reporting. In short: it answers the question, “How much power is this using, and how does it behave under load?”
Power quality analyzers are diagnostic instruments that identify and document power quality problems, especially when equipment is tripping, overheating, malfunctioning, or failing prematurely. In addition to core power parameters, PQAs are built to capture and characterize electrical disturbances like harmonics/THD, voltage sags (dips), swells, interruptions, transients, inrush events, and waveform anomalies (capabilities vary by model). PQAs are typically the best fit when for finding root-cause evidence, not just “what the load is,” but “what’s happening on the line that could be causing issues.”
Power loggers are built for long-term monitoring and trending of power and energy. Instead of short-term spot measurements, a logger is intended to be installed and left in place to capture how loads change across operating cycles, shifts, or seasons. Power loggers typically record voltage, current, power (kW/kVA), power factor, energy (kWh), and demand/peak loading over time. They’re ideal for building a clear load profile, identifying peaks, confirming run-time patterns, and supporting capacity planning, especially when time-stamped data is needed to document what happened and when it happened.
A power quality logger is designed to record power quality conditions over time, capturing both trends and disturbance events that might be intermittent or difficult to reproduce on demand. Most PQ loggers can track RMS parameters, as well as log events such as sags, swells, interruptions, and harmonic distortion, making them a strong fit for documenting utility supply issues, correlating downtime with electrical disturbances, or gathering evidence before deeper troubleshooting.
Power analyzers and loggers share many core measurements, but they are applied differently based on whether the objective is precision measurement, long-duration trending, or power quality event capture.
