Harmonic Analyzers
Harmonic analyzers measure and characterise the harmonic content of voltage and current waveforms, quantifying individual harmonic orders, total harmonic distortion (THD), inter-harmonics and related distortion that affect equipment, losses and supply quality. They support energy audits, EMC and supply-quality assessment, and troubleshooting of non-linear loads such as drives, rectifiers and LED lighting, making them a focused sourcing item for EU and GCC utilities, audit firms and electrical distributors.
The family overlaps with power-quality instruments but emphasises harmonic measurement: hand-held harmonic/power-quality analyzers and fixed harmonic monitors. A key reference is IEC 61000-4-7, which defines the measurement methods and instrumentation for harmonics and inter-harmonics, often applied alongside IEC 61000-4-30 power-quality methods. Key specification parameters include the highest harmonic order measured, the FFT/grouping method, voltage and current input ranges and sensors, sampling rate, and logging. Instrument safety is governed by IEC 61010-1 with a measurement category and voltage; EMC under IEC 61326-1.
Construction typically uses a rugged, often IP-rated field enclosure with CAT-rated leads and flexible or clamp current sensors, plus panel/DIN formats for fixed monitoring. Options commonly include flexible current probes, communications (Ethernet, Modbus), event logging, and reporting software for compliance documentation.
Configuration choices that matter at inquiry stage include the highest harmonic order and measurement method, current-sensor range, logging and communications, and whether traceable calibration is required. Himalay's verified manufacturer partners supply harmonic analyzers with test reports and CoC, CE (LVD/EMC), and RoHS/REACH, with SABER (Saudi Arabia) coordinated as part of the standard order flow; ISO/IEC 17025 calibration and traceability or factory acceptance testing are arranged where specified.
