SXWH Wireless Phase Detector is applied to phase position and sequence detection for power circuit and substation.
♦ Composed by: Control Unit (receiving), X Collector (transmitting), Y Collector (transmitting), needle type and hook type collector probes, extensible insulation rod and others accessories.
♦ Adopts digital circuit, full functions, and low power consumption, only to change one battery every one year if in normal operation.
♦ The control unit screen to display low voltage alarm if X, Y collector or control unit’s power is low voltage.
♦ Safe and reliable:
X and Y collectors transmits the collecting voltage phase position signal to the control unit, with reliable isolation performance of high voltage electrical safety.
High anti-interference ability, data is stable and accurate.
♦ Easy to use:
Control unit can be power off automatically.
On-site phase detecting doesn’t need any connecting wires. Phase detecting distance can reach 70m, and no influence by on-site environmental conditions.
The whole phase detecting process can be finished within 2 minutes by two operators.
♦ More functions:
Phase can be detected between two different voltage degrees, not only used for qualitative measurement (same/out of phase), but also used for quantitative measurement (phase angle difference of two supply line: 30°,60°and etc.).
Phase sequence measurement: positive phase sequence 120°, negative phase sequence 240°).
Electrical inspection function: When the X or Y collector contact with the live part of HV line or electrical equipments, if the line or equipment is live, the control unit will display X or Y.
♦ Control unit to show: wireless HV phase detector, same phase, out of phase, angle, X, Y, , .
♦ Backlight button
♦ Auto power off: 15 minutes standby then auto power off.
♦ Sample rate: 3 times/second.
♦ Build-in power supply: the control unit battery model is NEDA/604/6F22、9V or same style battery. X and Y collectors batteries are AG13、1.5V.
