Description

The control transformer, T2, is used for ASTAT control power, coils, radio remote controllers and other elec

tronic equipment. The commonly used sizes are 2 kVA -10 kVA (110 V) or 20 kVA (220 V). Transformers

smaller than 2 kVA are not recommended as the short circuit voltage might be too low with risk for non

satisfactory tripping conditions for MCBs and voltage drop for coils.

In the range 2 – 20 kVA a normal short circuit voltage is 4%.

The size in kVA is mainly given by the Pull-in power of the largest contactors that are energized at

the same time. Normally it is one of following factors that will decide the size of the transformer:

  • Main contactor(s) of the crane
  • Contactor of main hoist; if two motors are used for main hoist this should be considered
  • Four contactors of a large four-corner crane travel motion

The holding power for contactors is small compared with Pull-in. Also the thermal power of ASTAT control

power, radio remote controllers and other electronic equipment is very small compared with Pull-in of con

tactors. Chose a transformer so the voltage drop is maximally 5% in the most critical situation.

ASTAT works in the way that no rotor contactors are pulled if the main contactor is not already pulled, and if

two rotor contactors for the same motor should be closed, there is a short time separation between the op

erations of the different contactor coils.

If the transformer size tends to grow larger than 10 / 20 kVA, DC-coils for the largest contactors will help to

reduce the size due to their lower Pull-in power in kVA.

Practically, the discussion above leads mostly to a selection of a 2 kVA transformer for cranes with a main

contactor of maximally 300 A.
