Metrohm WPC1000 Wireless Phase Comparator

The WPC1000 Transmitter (TX) and Receiver (RX) are battery operated electronic contact devices that give clear visible indication of the status of the line under test, and are able to determine the phase relationship between two points at the same nominal voltage and frequency, by means of super bright LED’s and a high intensity buzzer. This ensures clear indication even inconditions of bright sunlight and high back ground noise. Each module must be used inconjunction with suitable insulating operating rods, to ensure a safe working distance from the HV source. WPC1000 - Transmitter Visual Indication Two RED LED’s. FUNCTIONS Voltage checking when the unit touches the live conductor, and if the voltage on the conductor is above the voltage threshold setting of the Transmitter,it starts automatically the voltage checking sequence, after 5 secs if the line is live, both RED LED’s will light solid and the Line Phase Angle is transmitted to the Receiver. WPC1000 ? Receiver Visual Indication ? One RED LED and One GREEN LED. Audible Indication ? Buzzer. FUNCTIONS Voltage Checking when the unit touches the live conductor, and if the voltage on the conductor is above the voltage threshold setting of the Receiver, it starts automatically the voltage checking sequence, after 5 secs if the line is live, the RED LED will light solid. In?Phase Indication When the phase angle shift between the Transmitter and Receiver is nominally ?+10°, the IN PHASE condition is indicated by RED LED lighting solid, GREEN LED lighting solid and the Buzzer sounding continuously. Out?of?Phase Indication When the phase angle shift between the Transmitter and Receiver is nominally >+20°, the OUT OF PHASE condition is indicated by solid RED LED lighting only.
