How Significant Is Harmonic Analysis in South African Firm? - Carelabs South Africa

How significant harmonic analysis is for a South African firm depends on what's already running on its electrical system. A facility with mostly linear loads and no power-factor correction capacitor banks carries relatively low harmonics risk. Add variable-speed drives, UPS systems, or a capacitor bank, and the picture changes — nonlinear loads inject harmonic currents, and capacitor banks can shift the system's resonant frequency toward one of those harmonics, amplifying a problem that would otherwise be minor. Carelabs measures actual distortion with a harmonics analyser and models impedance versus frequency to check for that resonance risk before it causes equipment malfunction, nuisance breaker trips, or metering errors. Every engagement concludes with a SANS 10142-aligned report package, with mitigation recommendations — harmonic filters, relocated capacitance, or higher-pulse-number rectifiers — where levels run high.
