motor! When using expanded settings for the ASTAT-XT you must be extremely
careful to avoid damaging the motor or ASTAT-XT.
•
Only cancel Phase Loss protection when the operator is sure that no real phase
loss exists and Phase Loss protection is activated.
This situation can occur in rare cases when there is no real fault but the ASTAT-XT
recognizes unusual behaviour like when THDV (Total Harmonic Distortion in
Voltage) in the network is high.
If this is a true case of Phase Loss then after cancelling Phase Loss protection the
motor will single phase and most likely be tripped by the over load protection
mechanism.
