  "textContent": "A VAR compensator includes a voltage detection circuit configured to detect voltage fluctuations in a power distribution system and stabilizes voltage of the power distribution system by controlling reactive power to be injected into the power distribution system based on an output signal from the voltage detection circuit. The voltage detection circuit includes: a three-phase amplitude computing circuit configured to compute amplitudes of the respective voltages of the three phases in the power distribution system; and a maximum deviation intermediate value computing circuit configured to compute an intermediate value between a voltage value of a phase having a large voltage and a voltage value of a phase having a small voltage out of the three-phase voltages based on a signal from the three-phase amplitude computing circuit.",
