Direct answers to the questions we hear most before a project starts. If yours isn't here, ask us directly — we respond within one business day.
A power quality audit measures and analyses electrical supply quality — harmonics, voltage fluctuations, flicker, and power factor — to identify issues before they cause equipment failure, nuisance tripping, or utility penalties. It's typically commissioned after repeated equipment failures or unexplained trips, when utility power-factor penalties appear, or before adding harmonic-heavy loads such as VFDs, UPS systems, or EV chargers.
A relay coordination study checks that protection devices — relays, fuses, breakers — trip in the correct sequence, so a fault clears with minimum disruption elsewhere in the system. An arc flash study calculates the incident energy at each piece of equipment to determine the PPE category and safe working boundary for personnel. The two are related — arc flash results depend on relay clearing times — but relay coordination is about system selectivity, while arc flash is about personnel safety.
If you already have recorded data from a compatible Class A power quality meter, we can proceed directly to analysis and reporting with no site visit required — our approach is tool-agnostic. If you don't have your own instrumentation, we can arrange on-site measurement, including meter rental where needed.
Most single-facility power quality audits take 3–7 days of on-site logging followed by 5–7 days of analysis and reporting, though this varies with the number of measurement points and the phenomena being investigated. Studies that need to capture intermittent events, such as voltage sags or swells, may need continuous logging over 1–4 weeks.
Depending on the study, we reference IEEE 519-2022 for harmonics, the IEC 61000 series for power quality phenomena, IEEE 1584 for arc flash, IEC 60909 for short-circuit calculations, and ISO 50001 / BEE norms for energy efficiency, among other standards specific to each offer. As one example, IEEE 519-2022 commonly limits voltage THD to 5% at the point of common coupling for general systems below 69 kV — the exact limit that applies to your facility depends on system strength (SCR) and is confirmed as part of the audit, not assumed upfront.
No. We don't sell equipment or earn referral commissions — our role ends at the validated recommendation. As part of that recommendation, we tell you which OEM(s) are the right fit for your requirement, and can connect you with multiple solution providers for competitive quotes. You choose the vendor and place the order.
Describe your facility and what you're seeing — we'll tell you which offer fits, or point you elsewhere if we're not the right fit.
