Power Quality Solutions
Assess, Analyze, Align
Power quality issues silently drain your profits. Modern electronic equipment generates harmonics that ripple through your distribution network, triggering a cascade of expensive failures: transformers overheating, motor burn outs, nuisance circuit breakers trips, and cables run hot. Meanwhile, electricity bill reflects a low power factor creeping toward 0.80 , that results in penalties. Low pf multiplies KVA charges; high harmonic distortion adds another penalty layer on top. The combined hit? A facility running three-shift operations can bleed millions annually in needless charges, premature equipment replacement, and unplanned downtime.
Already have some sort of power quality devices? Traditional APFC capacitor banks were designed for stable, linear loads of the 1990s. They simply cannot keep pace with modern load swings measured in milliseconds. When a VFD ramps up, the capacitor bank reacts with a lag, long enough for voltage to sag, equipment to misfire, or production to stop. Worse, in harmonic-rich environments, capacitor banks resonate and amplify distortion rather than correct it, pushing THD well beyond IEEE 519 limits and breaching utility regulations.
Static VAR Generator for Power Factor Improvement
ValBrid's Static VAR Generator (SVG) delivers fast, dynamic, real-time power factor correction that outperforms traditional capacitor-based APFC systems. With a response time of just 10–20 milliseconds, it instantly compensates for rapid load fluctuations and transient events to maintain unity power factor (≥0.99).
Built on an IGBT-based, three-level inverter topology, the SVG ensures a pure sinusoidal waveform, balances three-phase loads, and provides superior voltage regulation with bi-directional reactive power correction in both lagging and leading modes. It features a compact, modular design scalable from 50 KVAR to 800 KVAR per unit. Multiple units can be combined to achieve several MVARs, making it ideal for applications from SMEs to large manufacturing plants.

Active Harmonic Filter for Harmonics Mitigation
Harmonic distortion originates from non-linear loads and semiconductor devices. Per the IEEE 519-2022 standard, the total harmonic current distortion (THDi) at the point of common coupling should remain below 8%, while individual harmonic orders should be limited to 5%. When THDi exceeds these limits, transformers overheat, cables carry excessive neutral current, circuit breakers trip under normal load, and pf correction capacitors fail prematurely.
ValBrid’s IGBT-based Active Harmonic Filter (AHF) employs a three-level topology to deliver fast response and compact modular design while mitigating a wide harmonic spectrum—from the 3rd up to the 50th order. Unlike passive filters tuned to fixed frequencies, the AHF dynamically adapts to changing load conditions and multiple harmonic sources. It is available in scalable modules from 50 KVA to 400 KVA, with multiple units configurable to deliver multi-MVA harmonic compensation capacity

Power Quality Audit
Comprehensive diagnostics form the foundation for all our power quality solutions, ensuring targeted and effective interventions. ValBrid’s power quality audit delivers a comprehensive baseline assessment of your electrical distribution system. Utilizing advanced power quality analyzers, data loggers, voltage recorders, clamp meters, and transient disturbance monitors, experienced engineers deployed at sites systematically measure voltage, current, harmonics, power factor, flicker, voltage sags and swells, and transient events throughout your facility.
This audit uncovers root causes of unexplained trips, elevated electricity bills, equipment overheating, and compliance breaches. Data logging conducted over periods ranging from one day to several days captures load profiles, reactive power demand, total harmonic distortion (THD), and harmonic order breakdowns. Armed with this data, our experts perform detailed power system diagnostics using industry-standard analytical software to model, simulate, and interpret the power quality behaviors and non-compliance scenarios.
The deliverables include comprehensive analysis reports, scenario-based sensitivity studies, power factor trends, harmonic spectrum charts, and actionable recommendations supported by ROI calculations. This diagnostic phase enables precise, well-targeted solutions to maximize efficiency and cost savings, avoiding costly oversized or generic installations.
