The laboratory of mechanical and environmental tests
The high-voltage apparatus are exposed to various mechanical and climatic loads while in service.
The switchgear is exposed to mechanical loads at performance of closing and opening operations. The live tank apparatus are exposed to wire tension, wind and ice loads.
The following tests are carried out in our laboratory:
For the mechanical serviceability:
The electric devices are exposed to the influence of negative environment factors in service. The certain types of environmental tests are chosen due to design features of electric devices and the requirements formulated in the technical documentation regarding an influence of environment factors:
The tightness test of the gas-filled apparatus are performed by the instruments allowing to determine the leakage not less than 0,1 % per year of the mass of the gas contained in the apparatus.
Depending on design of apparatus and rated parameters we are able to perform the temperature rise test by currents of up to 25 кА:
The procedure of all test types is governed by the normative documents on electric apparatus and strictly regarded.
