3.5.1 Temperature-rise test
Fundamentals
Using the temperature-rise test, the temperatures under load at defined measuring points are
determined.
Test procedure
1. The drive is operated for eight hours in the test mode the same as in the "Load test without
motor".
2. The temperature is measured after eight hours at the following measuring points:
– Air discharge 1 at the transformer unit: Fan -E31
– Air discharge 2 at the cell unit: Fan -E32
– Transformer core: At the upper side of the core close to terminals T1:H1, T1:H2, T1:H3
– Reactor core: At the upper side and center of the core (only for option L09)
– Ambient temperature
Result
The measured values are documented together with the "Functional test plan".

3.5.2 Temperature behavior of the infeed transformer
Fundamentals
In addition to the temperature-rise test, the temperature of each of the windings of the infeed
transformer is measured before and after the temperature-rise test. This test can only be
ordered in conjunction with a temperature rise test.
Test procedure
1. The temperatures of the individual windings are determined before the temperature rise test.
2. The drive is operated for eight hours in the test mode the same as in the "Load test without
motor".
3. The temperatures of the individual windings are determined after the temperature rise test.
