It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...

Voltage unbalance can be a common steady-state power quality problem that is harmful to 3-phase electric motors. The condition can cause overheating and insulation damage. The cost of damage to motors ...

Thanks to ongoing innovations in technology, electrical engineers' approach to motor protection has changed over the years. The traditional strategy to large AC motor protection (e.g., over 500 hp), ...

Motor applications are on the rise, and the dramatic reduction in the cost of power MOSFET devices over the last decade, particularly MOSFET gate-drive ICs for low voltage (less than 100 volts) ...

Compressor overheating is one of the industry's most serious field problems today. Compressor overheating is usually caused by high compression ratios. High compression ratios can be caused by a ...

The shift from 12-V supply rails to 48-V power systems is pushing power levels under the hood to new highs. But it opens the ...

Early detection of increased temperatures helps avoid power distribution asset-related failures and unplanned shutdowns. Wireless technologies make implementing this predictive maintenance solution ...

Designed specifically for high-voltage sensing, a new generation of optically isolated amplifiers make monitoring and system protection circuits more accurate and easier to design. These iso-amps can ...

A Q&A with Moortec CTO Oliver King. What exactly do we mean by Adaptive Voltage Scaling versus Dynamic Voltage Frequency Scaling? Adaptive Voltage Scaling (AVS) involves the reduction of power by ...
