HZ-8800Y Remote Voice Wireless High Voltage Phasing Sticks Tester

Product introduction
HZ-8800Y High Voltage Phasing Sticks Tester is used to check whether the high-voltage phase is in phase and whether the phase sequence color is correct. Can also be used for close-range grid or ring network nuclear phase. The instrument is suitable for live working on 5V ～ 220kV transmission lines and live working on the secondary side.
The instrument adopts wireless transmission technology, which is safe and reliable in operation and convenient to use, and overcomes many shortcomings of the wired nuclear phase detector. And using GPS timing technology, two (or more) instruments can be separated by hundreds of kilometers of nuclear phase.

Working principle
The transmitter can determine whether the line is live, measure the phase and frequency of the line, and send the measurement data to the host. The host measures the time after the GPS is timed. The phase difference between the two hosts is the phase difference between the two lines. phase.
The core of the measuring principle of the instrument is the time difference between the two mainframes. Using GPS timing to synchronize the time of the two mainframes, the synchronization difference is less than 10 nanoseconds. The phase error introduced thereby is less than 0.1 degree.

Safety matters
1. In the field test, the operation should be performed according to the safety distance standard of the high-voltage test of the electric power department.
2. The standard configuration of the insulation rod is 3 meters, and the corresponding voltage level is ≤220kV. Such as measuring line electricity
When the voltage is higher than 220kV, please use an insulation rod with a length of more than 3 meters.

Technical parameters

Phase difference accuracy: The error is ≤5 °.

The voltage measurement range is 0 ～ 220kV.

The maximum transmission distance between the transmitter and the receiving host is about 100 meters.

Judgment of results (in-phase, out-of-phase) adopts A-level standard, phase difference ≥30 ° is out of phase, and phase difference <30 °="" is="" in="">

The two receiving hosts measure a distance of 300 meters to 800 kilometers.

Automatically switch between GPS mode and time mode according to the strength of the GPS signal.

Prompt:
(1) Some models of switch cabinets are equipped with live displays, which have power take-off points, which can be used for nuclear phase. This method is a secondary-side nuclear phase, and whether the nuclear phase result is correct or not depends on whether the corresponding relationship between L1, L2, and L3 and the bus bar is correct.
(2) Only one host is used for close-range nuclear phase, and the transmitter X / Y is used in pairs. During long-distance nuclear phase, two hosts are measured far away, but each host only measures with the Y series transmitter.
The general close-phase nuclear phase operation method of high-voltage transmission lines X and Y transmitters are respectively connected to the high-voltage lines with insulating rods. After the host is powered on, select the close-range measurement interface and watch the measurement results.
