[Industry Information] Optimizing Distribution Network Protection: Coordination Between Compact Modular Reclosers and Transformers
04-30-2025

Distribution transformers and Compact Modular Reclosers (CMRs) form a coordinated protection and automation solution on medium-voltage overhead networks. Transformers step down voltage for end-use, while CMRs detect and interrupt faults upstream—discriminating transformer inrush, coordinating with transformer protection relays, and automatically restoring service. Together they minimize outages, protect equipment health, and support smart-grid functions such as FLISR and condition-based maintenance. Read More

[Industry Information] Understanding On-Load and Off-Load Tap-Changing Transformers: Key Differences and Applications
04-22-2025

Transformers are fundamental components in electrical power systems, ensuring efficient voltage regulation to meet varying load demands. A critical aspect of transformer operation is the ability to adjust the voltage levels, which is achieved through tap-changing mechanisms. These mechanisms are categorized into two primary types: On-Load Tap-Changing Transformers (OLTC) and Off-Load Tap-Changing Transformers (NLTC). Understanding the distinctions between these two can aid in selecting the appropriate transformer for specific applications. Read More
