摘要： PROBLEM TO BE SOLVED: To continuously measure operation time, recovery time in the same test process by absorbing the time until a relay reaches a balanced state with a failure standby time timer in response to a failure state. SOLUTION: A CPU 6 switches, in accordance with a measurement start command, an output to a protection relay 1 to be tested from a stationary state oscillator 2 to from a failure state oscillator 3. At the same time, the CPU 6 starts a response time timer 6a. The measurement is stopped when the relay 1 is closed and a measured value is displayed as an operation time when the relay fails. Meanwhile, a failure standby time timer 6b starts to measure when the relay 1 is closed and stops a set predetermined time later. During the failure standby time, the testing apparatus keeps a test operation condition and controls a transient phenomenon brought about to a winding or the like. Then, the timer 6a starts to measure a stationary state from the output of the oscillator 2. A predetermined tome later, the relay 1 is opened, whereby the timer 6a finishes the measurement and displays the measured result as a recovery time to a display device 8.

摘要： PROBLEM TO BE SOLVED: To perform fine di/dt adjustment on a Weil circuit current in the vicinity of a zero point of a short-circuit current in the case of only the value of the Weil circuit current increasing. SOLUTION: A Weil combination test circuit comprises a current source circuit 1 for passing a main current I through a tested circuit breaker CBT and a Weil circuit (voltage source circuit) 2, the Weil circuit 2 having a vibration current circuit 4 for superimposing a high-frequency vibration current on the tested circuit breaker when cutting off the main current I and a circuit 5 for transient voltage adjustment parallel-connected to the tested circuit breaker. When respective parameter values of a transient recovery voltage and the value of frequency of a current Ics of the Weil circuit are the same as their standard values but the value of the current ics of the Weil circuit does not agree with its standard value, a resistance R2 of mΩ order is set in series with a discharge gap "gap" in the Weil circuit 2, thereby reducing the value of the current Ics to decrease the di/dt, thus facilitating the operation of the di/dt based on the fine adjustment of the current Ics.

摘要： PROBLEM TO BE SOLVED: To provide a field test method for a differential relay using an inrush current capable of enhancing a reliability of an operation test of the differential relay by omitting disconnection/connection work and simplifying the operation test by omitting a power source for testing. SOLUTION: Power equipment 13 has a power source 11 connected to its upstream side and an inductive instrument 12 comprising a transformer and/or a reactor connected to its downstream side. First current detecting devices CT1 and CT2 are respectively installed on the upstream side and the downstream side of a protection object section of the equipment 13. The field test method detects an abnormality in the protection object section by using current values i1 and i2 detected by the detecting devices CT1 and CT2 and further makes a judgement on connection of the relay 16. The inductive instrument 12 is turned on, and then the connection of the relay 16 is judged to be good or not on the basis of a shift between waveforms of both excitation inrushing currents inputted to the relay 16 by power-on of the instrument 12.

摘要： PROBLEM TO BE SOLVED: To test the operation of a breaker to trucking short circuits. SOLUTION: This tracking-ready breaker is provided with a test circuit. In the test circuit, by the control of an MPU 13, a pulse circuit 18 outputs a pulse waveform of a frequency different from the electric source waveform of a current passing through wiring paths 4 when a test button 17 is turned on. A contact of an instantaneous opening/closing circuit 19 formed by passing a serially connected contact and a current limiting resistor through a current transformer 5 and connecting to the wiring paths 4 is continuously opened and closed by a pulse signal of the pulse circuit 18 to extract the electric source waveform on a random basis to generate a pseudo-tracking current.

摘要： PROBLEM TO BE SOLVED: To shorten transfer time from a workstation 12 preparing dummy failure waveform data to an oscillator OSi transforming the data to an analog signal, in a dummy transfer device 11 which inputs the dummy failure waveform in place of the secondary output or a transformer to protective relays RYi which perform mutually cooperative action that are installed in a substation and mutually perform cooperative action by being connected by transmission and distribution lines, a failure state to inspect the cooperative action. SOLUTION: The dummy failure waveform data prepared at the workstation 12 is transmitted from a transceiver TX1 to a transceiver RXi via the Ethernet 15. An interface IFi extracts corresponding data from the adress of GPIB bus Bi added on received data, and outputs them to the oscillators OSi. Therefore, the dummy waveform data are simultaneously transmitted to each oscillator OSi in a short time and whether desired performance is obtained by this verification work can be verified in a short time.
