Devices and components determined for outside operation, have to function faultlessly even under extreme climatic conditions. Under these circumstances, power supply is extremely important. A test in our climatic chamber reveals, whether or not all necessary variables have been considered in the construction process. A variety of conditions can be simulated here.
Amongst others:
|
| • |
Temperature cycle testings under mechanical strain on:
- Composite isolators according to IEC 61109
- Composite housed isolators to IEC 61462
- Metal oxyde surge arresters according to IEC 60099-4
|
| • |
Testing of the correct operation of disconnectors under icing conditions, according to IEC 60694.
|
| • |
Testing according to manufacturer's specifications, within the framework of the technical data. |
