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 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 ...

HONG KONG--(BUSINESS WIRE)--TE Connectivity (TE), a world leader in connectivity and sensors, has designed a new 10A TV-8 rated OJT relay to meet market needs for high inrush capability, without ...

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

Although electromechanical relays have historically been the primary load switch in most applications, MOSFETs have been encroaching on the relay's territory in recent years as technology advances ...

This file type includes high resolution graphics and schematics when applicable. According to the research firm IHS Inc., about 54 million relays and timers were purchased in 2013, a number projected ...

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 ...
