Abstract
The present disclosure uses a capacitive voltage divider to supply a voltage that can be more readily handled by main-stream semiconductor and magnetic components (generally less than 1000 volts). The divided system voltage, expected to be between 500 and 1000 volts, is then converted to a power supply voltage to be used by the measuring equipment. For safety reasons, this voltage is frequently required to be less than approximately 50 volts if it is delivered via a connectorized cable with exposed contacts.
Claims13
A method of powering an electrical component with underground power lines, comprising the steps of:
- electrically coupling a power supply device to a conductor of the underground power lines;
- providing an input voltage from the conductor to a voltage divider of the power supply device;
- and
- regulating an output voltage of the voltage divider to support variable loads on the voltage divider.
A power supply device configured to power an electrical component with underground power lines, comprising:
- a connector configured to electrically couple the power supply device to a conductor of the underground power lines;
- and
- a voltage divider configured to receive an input voltage from the conductor, the voltage divider comprising a capacitor and divider voltage control electronics;
- wherein the divider voltage control electronics are configured to regulate an output voltage of the voltage divider to support variable loads on the voltage divider.
