Abstract
A voltage presence indicating system intended to be connected to a voltage measurement sensor for each phase of a high-voltage electrical network, a visual indicator representing the presence of the measured voltage, a first peak limiter having a first regulation voltage so as to deliver a first sinusoidal output signal representing the measured voltage and a second peak limiter having a second regulation voltage so as to deliver a second sinusoidal output signal representing the phase angle of the measured voltage, the second regulation voltage being higher than the first regulation voltage.
Claims9
A voltage presence indicating system intended to be connected to a voltage measurement sensor for each phase of a high-voltage electrical network, wherein the indicating system comprises for each phase:
- a visual indicator of the presence of a voltage measured by the sensor,
- a first peak limiter having a first regulation voltage so as to deliver, at a first output terminal, a first sinusoidal output signal representing the measured voltage,
- a second peak limiter having a second regulation voltage so as to deliver, at a second output terminal, a second sinusoidal output signal representing the phase angle of the measured voltage, the second regulation voltage being greater than the first regulation voltage.
