Can Your Transformer Protective Device Clear the Most Common Type of Faults?

Protecting power transformers in distribution substations is a critical power system application. Power transformers are expensive assets with long lead times—and the need to remove a power transformer from service to repair damage can have a big impact on power reliability for downstream customers. For these reasons, it’s critical to select an appropriate primary-side protective [...]

Solutions to Reduce the Shortest Power Outages

Momentary outages are expensive and inconvenient. As I discussed in a recent blog, momentary outages cost the U.S. billions of dollars every year. Today, there are new smart grid solutions that can limit the impact of these brief outages. Take self-healing grid technology. We’ve seen how it can make a huge impact in reducing sustained [...]
