Harmonics Analysis of the South African Electric Power System: - Carelabs South Africa

A harmonics analysis of a South African facility's electric power system starts with measurement: a harmonics analyser records the actual distortion present on-site, rather than assuming it based on the type of equipment installed. From there, Carelabs models system impedance versus frequency to check for resonance risk — a condition where the system amplifies a specific harmonic instead of just carrying it, often triggered by adding a power-factor correction capacitor bank to a system that already has significant nonlinear load. Where the analysis finds levels exceeding applicable limits, mitigation options include harmonic filters, relocating or adjusting power-factor correction capacitance, or specifying equipment with a higher rectifier pulse number. Every engagement concludes with a SANS 10142-aligned report package.
