EKG Technical Update: Electrical Panel Component Modernization & Power Factor Correction
Kuala Lumpur | February 13, 2026 — EKG M&E Sdn Bhd continues to demonstrate its multi-disciplinary expertise with the successful completion of a comprehensive electrical system overhaul. This project focused on the high-level maintenance and modernization of critical switchgear components within a main distribution board, ensuring system safety, operational reliability, and improved energy efficiency through power factor correction.
ELECTRICAL SYSTEM RESTORATION
Scope of Work: Component Replacement (Transformers, Contactors, Overloads) and Capacitor Bank Modernization
1. Problem Statement
Electrical panels are the central nervous system of any facility. Over time, heavy-duty components can experience thermal fatigue and mechanical wear:
-
Control Transformers: Inconsistent voltage output was affecting the reliability of the control circuit.
-
Contactors & Overloads: Pitted contacts and aged thermal overload relays increased the risk of motor failure and electrical arcing.
-
Capacitor Banks: Degraded capacitors were resulting in poor power factor readings, leading to potential utility penalties (Reactive Power Charges) and increased heat within the panel.
2. Technical Execution
Our electrical engineering team performed a systematic "strip-and-replace" procedure to restore the panel to its original design specifications:
-
Control Transformer Installation: Replaced aged transformers with high-efficiency units, ensuring a stable and isolated power supply for the panel’s logic and safety circuits.
-
Switchgear Modernization: Installed new, high-durability Contactors and Overload Relays. This prevents localized overheating and provides precise protection for the downstream motors and pumps.
-
Capacitor Bank Refurbishment: Replaced failing capacitor cells with new, high-specification units. This restoration is critical for maintaining a Power Factor (PF) close to unity (0.95–1.0), which optimizes the facility's electrical load and reduces current draw.
-
Testing & Validation:
-
Voltage Verification: Confirmed Phase-to-Phase Voltage stability (e.g., 415V/416V).
-
Amperage Audit: Verified that the amperage draw across all phases is balanced and within the rated limits of the new components.
-
Torque Testing: Every connection was checked for proper torque to prevent "hotspots" caused by loose wiring.
-
3. Project Outcome & Value Delivered
-
Improved System Stability: The new control components eliminate intermittent faults and ensure the mechanical equipment (pumps/HVAC) starts and stops reliably.
-
Energy Cost Reduction: By restoring the Capacitor Bank, the client will benefit from improved power factor, eliminating TNB/utility surcharges and reducing internal cable heat losses.
-
Enhanced Safety: Replacing aged overloads and contactors significantly reduces the risk of electrical fires and catastrophic component failure.
