U Cautions:

Controller hunting: When putting the capacitor bank into operation, it is required to avoid needless

switching cycles (means permanent switching on and off of steps without significant change of

consumer load). This so called “controller hunting“ would increase the number of switching operations

of the connected contactors and capacitors and decrease the expected life cycle (wear out) and, in

worst case, capacitor bursting and fire, etc . This can be avoided by a proper programming of the

BR604 with the actual system parameters (current transformer prim. and sec., first kvar step, control

series, switching time).

bursting and fire, etc
