Voltage measurement and wireless communication system

Abstract:

A voltage measurement system has a voltage measuring device connected to a device under test by a voltage divider to drop high voltages (e.g., peaking at or above 100 kilovolts) at a measurement point to lower levels for processing by a voltage measurement and wireless printed circuit board. The voltage measuring device communicates raw measurement data wirelessly (e.g., via Bluetooth.RTM.) to a remote device such as a mobile phone, laptop or portable meter head having a display and processing device programmed to calculate voltage measurements such has absolute average (ABS AVG), AC root mean square (RMS), +/-peak voltage, and AC or DC coupling. The remote device can wirelessly communicate with multiple voltage measuring devices to capture raw measurement data therefrom for voltage measurement applications with multiple measurement points (e.g., three-phase measurement, and transformer testing).
