Safely Inspect Electrical Systems with Ultrasound Electrical failures pose a tremendous safety threat and have the ability to shut down operations entirely Industrial plants require a lot of power to operate, and much like the machinery required for production, their electrical systems can also fail. The Importance of Maintaining your Electrical Systems The implications of a total electrical system failure are far more severe than that of an ordinary mechanical failure. They have the potential to damage equipment, cut power flow and cause downtime for days, seriously injure or kill workers in the immediate vicinity and even impact the surrounding areas power grid. Faults in electrical systems can be detected at their earliest stages with regular ultrasound inspection and therefor prevented far before anything catastrophic happens.

Elegant, latestgeneration electric heaters with security control system. Resistant to the wind and corrosive agents encountered in outdoor environments, they allow for several installation options and great performance. Tungsten 4000W is an infrared electric system with spectrum reflector which can be swiveled up to 45° and with intensity adjustment.

The Electroalfa primary distribution switchgear are designed for 7,2 and 24 kV rated voltages and rated currents up to 4000 A. Compliant with the technical standards of nationwide power generation, transport and distribution companies such as Transelectrica (the national transmission operator), CEZ Group, E.ON Group, Electrica Group (area distribution operators). The Electroalfa switchgear for primary distribution, of the S 12xx range, for a maximum voltage of 12KV c.a., have been tested for values of the continuous rated current of up to 5,000A and values of the rated peak withstand current of 50 KA/ 1s. This type of gear withstands the action of the internal electric arc, with a classification index of up to IAC AFLR 50KA, 1s. The switchgear from the range of S 24xx, for a voltage of 24 KV c.a. have been tested for values of the continuous rated current current of up to 2.500A and values of the rated peak withstand current of 25 KA/ 1s.
