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 ...

This month in EC&M's forum for your power quality questions, Mark McGranaghan, vice president of consulting services, teams up with several other experts from EPRI-PEAC to address the topics of ...

The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...

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 ...

However much care is taken, it is very difficult to keep all traces of transformer-induced hum out of the signal circuitry. It is highly irritating to find that despite the cunning use of low-noise ...

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 ...

A quasi-dynamic thermal model accurately predicts inrush-induced heating in MOSFETs, while also accommodating different circuit topologies. David Divins, Senior Field Applications Engineer, ...
