Flicker Analysis

Flicker refers to the rapid and repetitive changes in the intensity of light or voltage levels in an electrical system, often caused by variations in load current. While it may appear as a minor disturbance, flicker can have significant effects on the comfort of occupants, productivity, and the operation of sensitive equipment. Flicker Analysis is a specialized process aimed at identifying the root cause of flicker issues, evaluating their impact, and implementing solutions to ensure power quality and system reliability.

Why Is Flicker Analysis Important?

Flicker is not only a nuisance but also an indicator of underlying issues in the electrical system. Here's why flicker analysis is critical:

➤Improves Operational Efficiency: Minimizes disruptions in industrial processes and improves the performance of sensitive machinery.
➤Ensures Lighting Comfort: Reduces visual discomfort for occupants caused by fluctuating lighting levels.
➤Prevents Equipment Damage: Protects sensitive electronic devices and machinery from voltage fluctuations.

➤ Zero Compromise on Safety: Prioritize the protection of personnel and assets at all times.
➤ Regulatory Compliance: Ensure full adherence to safety and operational standards.
➤ Cost Efficiency: Minimize unplanned downtime and maintenance costs.
➤ Improved Performance: Optimize system reliability and efficiency.
➤ Sustainability: Support environmentally responsible operations.

Deliverables

Our Flicker Analysis service includes the following:

➤ Real-Time Monitoring:
     1. Use of advanced power quality analyzers to measure and record flicker levels over time.
     2. Identification of voltage and current variations causing flicker.
➤ Impact Evaluation:
     1. Quantitative analysis of flicker severity using parameters like Pst (Short-Term Flicker Severity) and Plt (Long-Term Flicker Severity).
     2. Evaluation of the impact on critical systems and processes.
➤ Root Cause Identification:
     1. Pinpointing the exact cause of flicker, whether from internal loads or external factors such as grid instability.
➤ Solution Recommendation:
     1. Customized solutions to mitigate flicker, including the installation of voltage stabilizers, power factor correction equipment, or dynamic compensation devices.
     2. Suggestions for optimizing load management and balancing.
➤ Compliance Reporting:
     1. Detailed report outlining observations, flicker severity indices, and recommended corrective actions.
     2. Assurance that the system meets international power quality standards.
➤ Post-Audit Support:
     1. Guidance in implementing corrective measures.
     2. Follow-up monitoring to ensure long-term resolution of flicker issues.
