Capacitor Health Checkup

Ensure Your Capacitor Bank Is Performing as Intended

Capacitor banks deteriorate over time due to aging, high ambient temperatures, harmonic resonance, and frequent switching cycles. A degraded bank causes poor power factor, excessive reactive power demand, and severe utility penalties. ActiveSine offers thorough health checkup and restoration services.

What is the problem?

Degraded Capacitors & Loss of Reactive Output

Capacitor banks deteriorate over time due to aging, excessive harmonics, high ambient temperatures, frequent switching, or component failure.

A weak or partially failed capacitor bank leads to silent power factor penalties, increased reactive power demand, and catastrophic rupture risks.

How ActiveSine Helps

Comprehensive On-Site Testing & Revitalization

ActiveSine evaluates the condition and performance of existing capacitor banks by assessing individual stages, real kVAR output, switching contactors, and protection parameters.

We identify defective or underperforming components and provide clear recommendations to restore effective reactive power compensation and safeguard your plant.

Audit Scope

What We Check During an Audit

Our technicians utilize specialized instruments to assess every vital component of your capacitor bank and APFC panel.

Actual Capacitance Value Measurement

High-precision LCR testing to determine degradation percentage across individual stages and cells compared to nameplate ratings.

Equivalent Series Resistance (ESR) & Loss Factor

Measures internal dielectric degradation and leakage currents that lead to thermal runaway and bulging.

Detuned Reactor & Tuning Frequency Verification

Testing impedance matching of series detuned reactors (e.g. 5.67%, 7%, 14%) to confirm harmonic blocking capability.

Switching Contactor & Thyristor Inspection

Evaluation of contact resistance, pitting, auxiliary contacts, and discharge resistor networks.

Thermal Infrared Imaging Scan

Identification of loose busbar terminations, hot spots, uneven phase currents, and cooling fan failures.

Step-by-Step Rejuvenation Plan

Detailed report specifying defective capacitors, reactor tuning adjustments, and recommendations to restore 0.99+ PF.
