Insulation flaws are an important factor in wear, efficiency loss and lifespan reduction of an electrical network. Nowadays, it is important to be equipped with good tools in order to reduce operational costs and save valuable time. The ULD-40™ enables making remote acoustic inspections with great accuracy. The equipment is user friendly and does not necessitate any training. One of the advantages of the ULD-40™ is that it works just as well in noisy environments.

Electrical arcs in the air and corona effects emit sounds and ultrasounds. The role of the ULD-40™ consists of capturing emitted ultrasounds and translating them to the audible range. The ULD-40™ accurately pinpoints and identifies corona effects and arcs that may be encountered on any type of high voltage installation simply by scanning around the suspected area. The ULD-40™ sensor is positioned in a directional amplifier cone that is integrated in the front of the enclosure.

An external parabolic sensor, which enables the user to pinpoint electrical defects from a longer distance, is also available. It easily connects on the side of the ULD-40™ and what’s more, it is equipped with a laser pointing device which enables pinpointing the ultrasound emission source. The dismountable parabolic sensor and the small dimensions of the ULD-40™ facilitate its use in the field and allow access to any type of installations.
