Power Quality Metering & Auditing

Overview

Power Quality Metering & Diagnostic Audits

Nairobi Power Engineers conducts on-site power quality audits and supplies permanent multi-function power quality analysers to industrial, commercial, and utility clients across East Africa. Using calibrated Class A power quality loggers conforming to IEC 61000-4-30, we record voltage dips, swells, transients, flicker, unbalance, and individual harmonic spectrums up to the 63rd order.

Our team delivers comprehensive engineering audit reports with root-cause diagnoses, single-line diagrams, payback calculations, and turnkey equipment recommendations to eliminate power-factor penalties and equipment failure.

FAQs

A standard comprehensive audit runs for 7 consecutive days (168 hours) to capture full operational shifts, weekend low-load conditions, and utility grid switching events.

Yes. Our meters feature native Modbus RTU (RS485) and Modbus TCP/IP (Ethernet) protocols that map directly into any third-party BMS or SCADA software.
