From lighting systems to the flight display, engine battery, and so much more, electrical devices have become a ubiquitous part of the modern aviation industry. As with any key components on board, it is important that these devices are kept in great working condition for as long as possible. As such, phase monitors are commonly used to protect many of the electrical systems from overvoltage, undervoltage, phase loss, and more. Working in conjunction with surge protectors, they can detect harmful conditions within electrical networks and shut off power to prevent lasting damage.
What Is a Phase Monitor?
A phase monitor is a type of control device that helps protect electrical systems from improper voltage or phasing. Specifically, it protects against too low or too high voltage, phase loss, phase reversal, and/or rapid short cycling by shutting a system down so that these problems will not hurt the equipment. Since phase monitors are only able to observe an electrical system and not directly affect it, they must be used alongside a surge protector if being used to prevent voltage issues. Either powered by alternating current (AC) or direct current (DC), phase monitors can be employed to give protection to three-phase loads, those of which are particularly powerful electrical arrangements that contain a set of three similar combinations of electrical components.
Types of Phase Monitors
As a versatile mechanism, phase monitors come in a variety of types to fit different applications. One major way to differentiate them is by whether the monitor is AC or DC driven. AC driven phase monitors shield three-phase loads and other powerful electrical assemblies from any harm or damage caused by unexpected phase changes. Since AC can be transmitted across long distances with minimal power loss in comparison with DC, it is often employed in very heavy-duty electrical systems like power lines. As such, AC driven phase monitors are often the preferred option for rugged protection applications. Conversely, DC driven monitors can be helpful for controlling devices that use DC like many car batteries and electric motors.
What Is the Purpose of Phase Monitors?
The main purpose of phase monitors is to detect central phase parameters like phase sequences, undervoltage, overvoltage, and phase failure, along with phase unbalance. This makes them a frequent tool in motor operations, where the phase monitor not only protects from voltage issues, but also any unapproved temperature conditions and disturbances caused by damaged fuses, cracked wires, or damaged contacts. Nevertheless, they are useful in a plethora of different applications and should be adequately applied to effectively shut off an electrical system when dangerous conditions are met.
