TYPE TESTS
|
|
Arcing fault tests
|
|
The protection of persons against arcing faults has our utmost attention. We thereby comply with the new IEC EN VDE 62271-202 regulation.
|
|
|
Electromagnetic Compatibility (EMC) < 100 µTesla
|
|
|
Dielectric Consistency
|
|
Checks for proof of dielectric consistency in the connections between the high voltage switchgear and the transformer (Type testing in accordance with IEC EN DIN 62271-202).
|
|
|
Mechanical stress
|
|
Tests to prove the resistance of the housing against mechanical stress (Type testing in accordance with IEC EN DIN 62271-202).
|
|
|
Definition of the housing temperature rate
|
|
Tests in accordance with IEC EN VDE 62271-202 confirms that warming up of the transformer inside the housing does not exceed the values for the same transformer, measured outside the housing, by more than 15K.

 |
Test occurs with the rated capacity of the station (here LCS-E with 630kVA , nominal current: 910A). |
Connections between the medium voltage switchgear and the transformer are tested after completion with 50 kV, 60 seconds. |
Considerable parts of the housing are tested with impact energy of 20 J, as shown and as described in IEC EN VDE 62271-202 Appendix C. |
Housing class LCS-E.7= 15 K with a 630kVA Transformer
(1)Po+Pk transformer losses
(2)Oil temperature without housing with an ambient temperature of 20 °C
(3)Oil temperature with housing with an ambient temperature of 20 °C
(4)Oil temperature with housing with an ambient temperature of 30 °C |
