These Detectors and Voltmeters are testing for VOLTAGE. Voltage is the potential difference between any two conductors or between a conductor-to-ground. Two conductors at different potentials result in current flow. Two conductors at the same potential and conductors at no potential both result in no current flow. Readings are a product of the current flow across the circuit calibrated to read as voltage in kilovolts.
What is Voltage Detection?
Voltage Detection is checking the voltage status of the line. The line’s status may have NOMINAL VOLTAGE, INDUCED VOLTAGE or be a CONFIRMED DE-ENERGIZED LINE. Each of these voltage categories are indicated by the meter reading.
What is nominal voltage?
Nominal voltage is the normal operating voltage of the electrical system. This is measured as either a phase-to-phase or line-to-ground value.
What is induced voltage?
Induced voltage is a hazardous voltage that is present on a de-energized line. This can be caused by either high current values in parallel lines at any voltage or high voltage transmission lines parallel to the deenergized conductors being worked on. The amount of induced voltage is dependant on the length the lines run parallel, proximity and load current in the energized line.
What is a Voltage Detector?
A voltage detector is a safety tool that alerts the user to hazardous voltages under various conditions and work situations. Voltage detectors are also a great way to save time while working in the field. Salisbury analog voltage detectors are calibrated to read in line-to-ground values, indicating the status of each line contacted. Saving time, solving problems, results in greater work efficiency.
What is Phasing?
Phasing is the process of determining if two energized conductors can be safely connected. When measuring voltage phase-to-phase, near zero volts indicate both conductors are of the same phase.
How is Voltage Detection different from Phasing?
A Phasing Voltmeter measures the voltage difference between two reference points (phase-to-phase or phase-to-ground). A Voltage Detector can establish only one reference point (the phase it contacts) while the other reference point (the live line tool attachment) is floating in an electrical field.
