WPC1000 Wireless Phase Comparator Kit

The WPC1000 Wireless Phase Comparator Kit utilizes a Transmitter module and a Receiver module to determine the Phase Relationship between two energized conductors at the same nominal voltage and frequency, eliminating the need for connecting cables. The kit is designed to comply with IEC 61481 standards for system voltages up to 36kV.

The WPC1000 Wireless Phase Comparator Kit includes various components housed within a purpose-designed ABS heavy-duty carry case. These components consist of:

WPC Transmitter (TX – Yellow)
WPC Receiver (RX ‐ Blue)
2x 40mm Hook Contact Electrodes
2x Bowthorpe Rod Adaptors or 2x Universal Star Wheel Adaptors
Accessories Bag attached to case lid
Polymer cleaning kit
Additionally, a Switchgear Kit is available to enable Phase Comparison in Switchgear applications.

The WPC1000 Transmitter (TX) and Receiver (RX) are battery-operated electronic contact devices that provide a clear visible indication of the line’s status. They utilize super bright LED lights and a high-intensity buzzer to accurately determine the phase relationship between two points at the same nominal voltage and frequency. This ensures clear indication, even in challenging conditions such as bright sunlight and high background noise.

WPC1000 Wireless Phase Comparator Transmitter (TX)
During voltage checking, the Transmitter unit establishes contact with the live conductor. If the conductor’s voltage exceeds the threshold, the Transmitter triggers and initiates the automatic voltage checking sequence. If the line remains live after 5 seconds, both RED LEDs illuminate solid, and the Line Phase Angle transmits to the Receiver.

WPC1000 Wireless Phase Comparator Receiver (RX)
Similarly, the Receiver Unit performs Voltage Checking by making contact with the live conductor. If the voltage exceeds the threshold, the Receiver activates and starts the voltage checking sequence. If the line remains live after 5 seconds, the RED LED lights up solidly.

To determine the phase angle shift between the Transmitter and Receiver, certain conditions are considered. An IN PHASE Condition indicates a phase angle shift nominally ≤±10°, shown by solid RED and GREEN LEDs and a continuous buzzing sound. However, an OUT OF PHASE Condition indicates a phase angle shift nominally >±20°, represented by a solid RED LED.

Please note that each module requires suitable insulating operating rods for safe distance from the HV source to ensure optimal performance.
