Quality Where It Counts: Transcat’s Power Quality Calibration Process

Transcat provides accredited calibration services for power quality analyzers and associated AC/DC power devices, helping you safeguard uptime, safety, and compliance with precise, traceable measurements. Our capabilities span DC/AC‑LF parameters and support a broad range of analyzer and power supply types used across industrial and utility power environments.

Our North American network of ISO/IEC 17025 accredited labs offers flexible service delivery—including in-lab, on-site, and in-process calibrations—to meet OEM specifications or your custom requirements for complex power systems.

Expertise That Elevates Your Power Quality Instrument Calibration

From linear and programmable power supplies to analyzers that capture harmonics, flicker, and transients, our accredited scope covers DC to 100 MHz for AC/DC power measurements and extends to advanced electronic/RF instrumentation when your analysis crosses disciplines. Our calibrations maintain true SI traceability through NIST within ISO/IEC 17025 frameworks.

From Power Supplies to PQ Analyzers: Power Quality Instruments We Calibrate

: Calibration for portable and benchtop PQ analyzers that measure voltage, current, harmonics, power factor, and transients.
: Comprehensive calibration for DC linear supplies, programmable sources, and variable AC/DC units—covering wide voltage/current combinations.
: Calibration support for wattmeters, power meters, and energy analyzers used in lab and field diagnostics.
: DC/AC‑LF coverage up to 100 MHz for sources used in PQ test setups and verification.
