RTD Biasing The 469 thermal overload curves are based solely on measured current , assuming a normal 40°C ambient and normal motor cooling. The actual motor temperature will increase due to unusually high ambient temperature, or motor cooling blockage. Use the RTD bias feature to augment the thermal model calculation of Thermal Capacity Used, if the motor stator has embedded RTDs. The RTD bias feature is feedback of measured stator temperature. This feedback acts to correct the assumed thermal model. Since RTDs have a relatively slow response, RTD biasing is useful for slow motor heating. Other portions of the thermal model are required during starting and heavy overload conditions when motor heating is relatively fast. For RTD temperatures below the RTD BIAS MINIMUM setting, no biasing occurs. For maximum stator RTD temperatures above the RTD BIAS MAXIMUM setting, the thermal memory is fully biased and forced to 100%. At values in between, if the RTD bias thermal capacity used is higher compared to the thermal capacity used created by other features of the thermal model, then this value is used from that point onward. Motor Start Supervision Motor Start Supervision consists of the following features: Time-Between-Starts, Start-per-Hour, Restart Time. These elements are intended to guard the motor against excessive starting duty, which is normally defined by the motor manufacturer in addition to the thermal damage curves.

 

 

Mechanical Jam and Acceleration Time These two elements are used to prevent m o t o r d a m a g e d u r i n g a b n o r m a l operational conditions such as excessively long acceleration times or stalled rotor. Phase Differential Protection This function is intended to protect the stator windings and supply power cables of large motors. Two types of current transformers connections are supported: • 6 CT’s externally connected in the summing configuration. • 3 Flux Balancing CT’s. Separate trip pickup levels and time delays are provided for motor starting and running conditions.
