What do current monitoring relays do?

Current monitoring relays protect equipment by detecting undercurrent (broken belt, empty pump) or overcurrent (mechanical jam, overload) conditions. Carlo Gavazzi monitors provide adjustable setpoints and time delays, with relay outputs for alarm or shutdown signals.

What is a phase monitoring relay?

Phase monitoring relays protect three-phase motors and equipment from phase loss, phase reversal, and voltage asymmetry. These conditions can cause motor damage, overheating, or incorrect rotation. Carlo Gavazzi phase monitors provide rapid detection and output contacts for motor starter control.

Can monitoring relays measure power factor?

Yes, Carlo Gavazzi offers power factor monitoring relays that measure the phase angle between voltage and current. Low power factor can indicate motor problems or capacitor bank failures. These relays help optimize energy efficiency and detect equipment issues before failures occur.

Current, Voltage & Phase Monitors

Product Brochure Carlo Gavazzi offers a comprehensive range of monitoring controls for monitoring of phase loss, incorrect phase sequence, phase unbalance, over/under current, over/under load, over/under frequency, and over/under voltage.

Gavazzi products include current monitors, voltage monitors, power monitors, phase loss relays, inverters, and current transformers.

These monitors are used in a wide range of applications for protecting motors against the damaging effects of single phasing and overloads (elevators, compressors, pumps, air conditioning systems, mixing tanks). They are also used extensively for monitoring instrumentation signals (4-20mA, 0-10V), verification of machinery operation, detection of broken heater elements, monitoring of lights in critical areas (runway lights at airports), monitoring of ventilation fans, and in building automation systems.
