Power Factor Correction (PFC) is a critical technique in electrical power systems used to improve the efficiency of power utilization and reduce energy losses. In industrial and commercial installations, where inductive loads such as motors, transformers, and fluorescent lighting are prevalent, poor power factor is a common issue that leads to higher currents, increased losses, and unnecessary costs.
As June begins, many regions around the globe enter their most demanding energy season. Rising temperatures bring increased use of HVAC systems, refrigeration, and cooling equipment—especially in industrial and commercial environments. For electrical engineers and facility managers, this means one thing: your systems must be ready for peak load performance.
Voltage regulation in transformers is critical to ensuring stable and efficient operation in electrical power systems. Variations in load or supply voltage can lead to deviations from the desired voltage levels, potentially impacting the reliability and performance of equipment and infrastructure. Two primary techniques for regulating transformer voltage are On-Load Tap Changers (OLTC) and Off-Load Tap Changers (Off-Load Options).
