Megger Ultrasonic leak and corona detector

The Ultrasonic Leak and Corona Detector is a low-cost, portable system that receives air-borne ultrasonic signals, converts them to the audible range, amplifies them, and displays the output visibly on a meter and audibly through a speaker or headset.

The system is designed for locating gas leaks and electrical corona sources, all of which emit strong ultrasonic signals that are inaudible to the unaided human ear.

Variously shaped collectors facilitate the quick location of ultrasonic sources; in particular, the new directional pickup horn allows pinpointing of discharges in high-voltage equipment while the operator remains at a safe distance.

The ultrasonic detection system shown above consists of the instrument with indicator and speaker, plug-in ultrasonic transducer probe, directional pickup horn attachment, sound concentrator attachment, and a headset. A carrying case is included.

Key Features of the Megger Ultrasonic Leak and Corona Detector

The Megger Ultrasonic Leak and Corona Detector is a state-of-the-art diagnostic tool designed for pinpointing and analyzing ultrasonic frequencies emitted by gas leaks and electrical corona discharges. This sophisticated instrument is invaluable for maintaining electrical equipment and ensuring the integrity of pressurized systems in various industrial applications.

• Detection Capabilities: The device is adept at detecting both pressure leaks in systems such as air, gas, and vacuum, as well as identifying corona discharges that can indicate potential failures in high voltage equipment. This dual functionality makes it a versatile tool for comprehensive maintenance routines.
• Ultrasonic Sensitivity: Utilizing advanced ultrasonic technology, the detector senses high-frequency sounds that are inaudible to the human ear. These sounds are generated by the turbulence of escaping gases or by the ionization of air surrounding electrical discharges.
• Adjustable Sensitivity: To accommodate various detection environments and to pinpoint faint ultrasonic emissions effectively, the device features adjustable sensitivity settings. This allows users to fine-tune the detector to distinguish background noise from genuine leak or corona sounds.
• Audio and Visual Indicators: Upon detecting ultrasonic emissions, the device provides immediate feedback through audio headphones and visual readings on a display panel. This dual feedback mechanism helps in quick and accurate localization of the source of the problem.
• Portability and Ease of Use: Designed with field operations in mind, the detector is lightweight and easy to handle, making it ideal for use in diverse locations, from crowded factory floors to remote outdoor substations.
• Applications: The Megger Ultrasonic Leak and Corona Detector is widely used in utilities to inspect transformers, switchgear, and other high-voltage equipment. It is also employed in various manufacturing settings to check for leaks in compressed air systems, valves, and tanks.
