Abstract: When closing converter transformers without load, inrush current arise due to the invalid suppression strategies, which pose a significant threat to power system. Studying the effect of ...

Inrush currents associated with motor starting and transformer energizing can cause interaction problems with other loads in a facility or on the power system. These inrush currents can cause sags ...

Nov. 13, 2008, PULLMAN, WA - Schweitzer Engineering Laboratories, Inc. (SEL) is now taking orders for two new products, the SEL-787 and SEL-487E Transformer Protection Relays. These are the first ...

A transformer switching onto a line can sometimes cause a circuit breaker to trip or a fuse to blow. This phenomenon occurs even if the transformer presents no load, such as when the secondary is open ...

Omicron's CT Analyzer provides fast and cost-effective testing and verification of current transformers for protection and metering applications. It automatically determines all relevant current ...

Omron Electronic Components Europe has launched a small footprint DC power relay that frees up PCB space but without compromising performance. The G5PZ-X is suitable for inrush protection circuits or ...

Phase-shifting transformers play an important role to control the power flow within our modern networks that include more and more renewable energy sources. The most important protection principle for ...
