IPC: H02H3/34
Filed: 1987-09-25
Abstract: PURPOSE:To detect accurately the impressed state of a conductor and the like in a low-voltage distribution line and thereby to detect the presence of a disconnection and an open phase, by measuring voltages of impressed elements of different phases to the ground and by subjecting any two voltages out of them to subtraction to calculate a line voltage. CONSTITUTION:Amplifier circuits 2, 3 and 4 are connected to a transformer PT1 for an instrument, and voltages obtained by amplifying an output of PT1 and being proportional to the voltages of phases to the ground are outputted from output terminals Pr, Ps and Pt. A differential amplifier circuit 5 calculates a difference in output between the circuits 2 and 3 of phases R and S as a line voltage and outputs same to an output terminal P1. Differential amplifier circuits 6 and 7 calculate differences in output between the circuits 3 and 4 of phases S and T and between the circuits 4 and 2 of the phases T and R, likewise, as line voltages, and output same to output terminals P2 and P3. A control circuit 8 receives line voltage signals from the circuits 5-7 as inputs, and when peak values of any two of these line voltage signals lower to the values being about one half of voltage values in a normal time, it judges that a disconnection or an open-phase trouble has occurred and outputs a trouble occurrence information to a transmitter-receiver 9.

Title: Loop gain control method for phase synchronizing oscillation circuit
Inventor: SUMIYOSHI HIDEO
IPC: H03L7/10
Filed: 1992-09-11
Abstract: PURPOSE:To provide a phase synchronization oscillation circuit which has a wide range of stale lock-in operations and also has a reduced steady phase error by using a synchronous state detecting means and then controlling the gain of a variable gain amplifier with the output voltage of the synchronous state detecting means. CONSTITUTION:A phase comparator 1 is provided with a set/reset flip-flop circuit. A 1st synchronous state detecting means 6 compared the phase of the reference signal inputted to the comparator 1 with that of the frequency dividing signal outputting from a frequency divider 5. Then the means 6 outputs the positive voltage when the difference between both phases is equal to about 180 deg. and then outputs OV when the phase difference is much different from 180 deg.. This DC output is applied to the gain control terminal a variable gain amplifier 3. The amplifier 3 reduced the gain when the DC output is equal to OV in order to prevent the generation of a blind sector. Thus a wide lock-in range is kept before a synchronous lock-in operation. Meanwhile the amplifier 3 increases the gain against the positive voltage to reduce the steady phase error after a lock-in operation.
