Temperature and Humidity
Measurements collected during PD testing can be affected by temperature and humidity. For
example, PD activity often increases with higher humidity. For these reasons, you should record
the temperature and humidity when conducting PD testing to ensure that you have consistent
conditions for reliable and comparable results. Ideally, the testing environment should be
controlled to provide consistent temperature and humidity. In any case, you should record the
ambient temperature and humidity levels during PD testing in case they vary from test to test.
NOTE: The temperature and humidity recording in this case is different from that described earlier for
compensating temperature and recording humidity for DC testing. PD testing does not use the DX features
for DC testing compensation and recording. For PD testing, recording ambient temperature and humidity is a
manual process.
