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 ...

R&D engineers have traditionally found it a challenge to measure dc inrush current and current during dc voltage transients because these measurements require complex setups with multiple pieces of ...

Omron Electronic Components Europe has launched the G5Q-HR, the latest addition to the G5Q family of 10A PCB power relays. Credit: Omron The new relays can achieve reduced power consumption and heat, ...

Acceptable ohm reading for a good current relay. One type of starting relay used on fractional-horsepower compressors is the current relay. This type of starting relay uses the initial high inrush ...

OMRON Electronic Components Europe has introduced the G9EJH-1-E, an ultra-compact DC power relay, delivering inrush protection in battery-charging systems up to 800V. The G9EJH-1-E is an ultra-compact ...

While consuming less electricity than their older, less efficient counterparts, high-efficiency motors are much more likely to trip their respective circuit protectors when they start. Initial ...

Often we try to find solutions to common power magnetics issues in engineering manuals. In the process, we encounter conflicting theories among publications with no definitive solutions offered. This ...

If used correctly, a reed relay is a superbly reliable device. The switch contacts are hermetically sealed, so they don’t suffer from oxidization or contamination in the same way as an open ...
