Power Quality Investigation

Monitor voltage variations, interruptions, sags, and swells that can affect sensitive equipment such as VFDs and PLCs. Our analysis helps identify the causes of voltage disturbances and supports measures to maintain stable and reliable plant operations.

Measure and assess Total Harmonic Distortion (THD) to identify power quality concerns and evaluate compliance with IEEE 519 limits. Our findings support the selection and sizing of appropriate active or passive harmonic filters.

Identify switching transients and lightning-related surges that may damage sensitive electrical and electronic equipment. Our assessment supports the design and coordination of Surge Protection Devices (SPDs) for improved system protection.

Evaluate voltage fluctuations and flicker associated with large motor starts and other changing loads. Our analysis helps determine suitable VFD or soft starter solutions to reduce voltage disturbances and improve network stability.

Assess existing power factor correction equipment and identify opportunities to improve system efficiency. We design appropriate automatic PFC solutions to maintain a stable power factor and help reduce power factor-related utility penalties.

Assess grounding and bonding systems to identify issues that may contribute to electrical noise and unstable reference voltages. Our measurements and inspections support reliable grounding performance for sensitive control and electrical systems.
