The microcontrolled PLM Series of octal plug-in three-phase voltage monitors protects three-phase motors and other sensitive three-phase equipment from damaging or destructive voltage faults, the ...

You should also look at factors such as effective input impedance (Z IN ), signal phase adjustment, and small physical package size when selecting the ADCs for a power-grid monitoring application.

AutomationDirect has added new phase and voltage monitoring relays from ProSense. The PMRU-2C series true RMS phase monitor relays protect 3-phase equipment from damage that can occur when there is a ...

The PLMU11 is a universal, three-phase line voltage monitor with a broad voltage range and full adjustability, says the manufacturer. According to the company, the octal plug-in, three-phase voltage ...

Having both 3-phase and single-phase loads can be challenging when trying to balance the voltages at a facility. It’s possible that during a facilities operation, one phase can be lightly loaded ...

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...
