WM Series Power Quality Analyzers

The nature of our voltage mains has changed greatly in the last 10 years. With the proliferation of non-linear loads such as inverters, power converters, switch-mode power supplies, and computers, there is a growing concern for the quality of our power sources.

Problems often arise which can cause equipment failure or shut-down resulting in significant costs and loss of production. Power quality problems can result in failure of compensation capacitors, tripping of fuses, over-heating of transformers and motors, failures of electronic equipment, and high neutral currents.

Carlo Gavazzi offers a broad range of power quality meters and transducers which give early warning of power quality problems - allowing preventative action to be taken before a major failure results. Most of our products offer relay outputs that can be used to immediately shut down a piece of equipment if a certain threshold is reached. Another option is to connect to your PLC or PC control system to provide plant wide monitoring of power quality using 4-20 mA current signals or via RS485 communications.

Carlo Gavazzi also offer a number of software products for monitoring of a network of meters and transducers. This allows at-a-glance viewing of your complete power system
