Socomec DIRIS A60 Class 0.2S Power Analyser

The Socomec DIRIS A60 Class 0.2S Power Analyser (model 48250061) is Socomec's highest-accuracy multifunction power measurement instrument, certified to Class 0.2S under IEC 62053-22 — the most demanding accuracy class available for revenue-grade active energy measurement with an accuracy of ±0.2% across a 50:1 current range. While the DIRIS A40 (Class 0.5S) addresses the majority of industrial submetering applications, the DIRIS A60 is specified for applications where the financial value of the measured energy is very large, where metrological disputes require the highest defensible accuracy, or where regulatory requirements explicitly call for Class 0.2S accuracy. In Saudi Arabia's context, these applications include ARAMCO's custody transfer metering verification, SABIC's high-value production cost allocation, power purchase agreement (PPA) boundary metering for industrial renewable energy projects, and substation energy monitoring at primary substations serving NEOM and major Vision 2030 infrastructure projects.

The DIRIS A60 builds on the DIRIS A40's measurement coverage and adds a significantly enhanced power quality analysis capability: it measures THD on voltage and current up to the 63rd harmonic (compared to the 31st on the A40), captures per-harmonic magnitudes and phase angles, logs waveform distortion trends with time-stamp, and can be configured to generate automatic power quality event reports. This extended harmonic analysis capability is directly relevant to Saudi Arabia's largest industrial consumers, where the proliferation of variable frequency drives, arc furnaces, and large rectifier loads in petrochemical and steel manufacturing facilities creates complex harmonic spectra that a 31st-harmonic instrument cannot fully characterise. ARAMCO's power quality study program for new plant approvals explicitly requires 63rd-harmonic resolution for current injection characterisation.

The DIRIS A60 offers Ethernet (Modbus TCP) connectivity as standard alongside Modbus RTU, allowing direct connection to industrial Ethernet networks without a serial-to-Ethernet converter. It also supports IEC 61850 GOOSE and MMS protocol for substation automation environments — a unique capability at this product level that makes the DIRIS A60 directly compatible with digital substations under IEC 61850 architecture, increasingly specified for new primary substations serving NEOM and other large-scale Vision 2030 infrastructure projects. For SEC-compliant primary substation installations, the DIRIS A60's Class 0.2S accuracy combined with IEC 61850 communication provides the complete measurement and communication solution in a single DIN-rail device.

Razz Middle East offers DIRIS A60 units with full metrology compliance documentation, calibration certificates traceable to SASO/national standards, and project support for substation integration including IEC 61850 configuration. Our team has experience with ARAMCO power quality study support and can provide site measurement campaigns using DIRIS A60 instruments as part of our electrical engineering services offering.
