High Voltage Wireless Phase Verification Instrument: Principles and Applications
1. Introduction
The high-voltage wireless phase verification instrument is a professional tool used for phase verification and phase sequence verification in power systems. It can be used to determine the phase relationship in high-voltage lines or substations, which is crucial for the safe operation of power systems.
2. Working Principle
Transmitting Unit: The transmitting unit generates a wireless signal of a specific frequency and sends it to the point to be tested.
Receiving Unit: After receiving the signal, the receiving unit determines the phase relationship between current and voltage by comparing the phase difference between the received signal and the transmitted signal.
Wireless Communication: Utilizes wireless communication technology for signal transmission, eliminating the need for physical connections, thereby enhancing flexibility and safety in use.
3. Main Functions
Phase Verification: Determines the phase relationship between two sets of high-voltage lines.
Phase Sequence Measurement: Detects whether the phase sequence in a three-phase power system is correct.
Voltage Detection: Determines whether a line is energized.
4. Technical Features
Strong Anti-Interference: Possesses excellent anti-electromagnetic interference capability, ensuring accurate measurement even in complex electromagnetic environments.
Wireless Communication: No need for wiring or junction boxes, simplifying the installation process.
