摘要： An airflow control system generates a compensating output which is combined with the normal damper control output in a damper operating device when a pole change motor driving a blower changes speed so that the damper is changed to compensate for the change in blower speed to avoid a large change in airflow. This overcomes the delay in the normal integrating damper control which produced unwanted fluctuation in airflow when the motor speed was changed.

摘要： An apparatus for detecting a ground fault occurring in a power system which furnishes an AC power from a variable-voltage variable-frequency power supply to a load via a voltage transformer. The apparatus compares a zero phase sequence current with a reference value and, upon detection of occurrence of a ground fault, produces an output signal representing the ground fault. Prior to such comparison, the zero phase sequence current is so processed as to be independent of the frequency of the power system or the reference value is so processed as to be dependent on the said frequency.

The number of the rotations of motor is controlled step by step in accordance with the flow rate of fluid flowing through a flowing path on the occasion of operating the motor with the variable frequency power supply of which the output frequency changes depending on a command request of the fluid flowing apparatus as a load, also controls the flow rate control device in accordance with deviation between the command request from the load and a staircase control input to the variable frequency power supply even when the flow rate changes minutely at each step. Fine control of the desired flow rate is achieved by adjusting the number of rotations of motor and the amount of the opening angle of the flow rate control device.
