Monitoring Configuration Description
Standard
This configuration uses the following:
• Three thermistors, connected in series, are incorporated in the coil ends of the
stator windings. T
Ref
=155°C (310°F) for medium-voltage drive units.
• Three Pt100 sensors, one for each phase, are incorporated in the windings.
There are three additional thermistors, and 3 additional Pt100 sensors, already in
place in the stator windings as reserves. See below for sensor markings.
Stators used in the 1.2–6.6 kV drive units are equipped with 3 Pt100 sensors marked 19:20, 21:22, and
23:24. These are connected at the plinth on the terminal plate. The stator is also equipped with a duplicate
set of 3 Pt100 sensors, marked 19s:20s, 21s:22s, and 23s:24s. This duplicate set is not connected to the
terminal plate as long as the first set of 3 Pt100 sensors are functioning; it is kept in reserve as a back-up
set. The ends of the reserve sensor leads are isolated, and leads bundled among the other cables, until the
back-up Pt100 sensors are needed.
