GUA-100E acoustic shock generator
Description
Application:
The GUA-100E acoustic surge generator is a special device used to locate insulation faults in power cables and shielded shielded cables for a rated voltage of up to 12 kV and was developed on the basis of Part III of Annex 21 to the Regulation of the Minister of Industry and Trade of April 14, 1995
The GUA-100E generator is designed to locate insulation faults in power cables and shielded sheathing cables supplying mining machines, stationary and mobile devices, installed in underground workings of a mining plant, as well as on the surface.
The GUA-100E generator is not intended for locating faults in cables and wires laid in the ground. The generator has been designed to ensure full safety for the operator.
Construction
The GUA-100E generator is made in a dustproof, rectangular metal casing. Handles for carrying it are welded to the housing. The generator also has a metal cover for the housing. The housing is protected against corrosion with varnish coatings.
The integral equipment of the generator is:
- three-wire power cord,
- ground wire with a clamp,
- test leads terminated with clamps.
