Project Description
Product Features:
The LT-800 high-voltage wireless phase nuclear instrument (hereinafter referred to as the “instrument”) is used to detect whether the power supplies on both sides of the circuit breaker in the loop network or dual power supply power network are in phase. The core phase operation must be performed before the two power supplies in the closed loop, otherwise a short circuit may occur. The instrument is suitable for the live nuclear phase operation of 6KV～220KV transmission lines, and has the functions of high-voltage electrical inspection and phase sequence verification.
The LT-800 high-voltage wireless phase phasor adopts wireless transmission technology, which is safe and reliable in operation and convenient to use. It overcomes many shortcomings of wired phase phasor and complies with the relevant national electrical safety equipment quality supervision, inspection and testing standards.
The LT-800 high-voltage wireless phase phasor adopts wireless transmission technology, high voltage wireless nuclear phaser.which is safe and reliable in operation and convenient to use. It overcomes many shortcomings of wired phase phasor and complies with the relevant national electrical safety equipment quality supervision, inspection and testing standards. Compared with the wired phase nuclear device, its main advantage is that it removes the leads connecting the two power grids (power), and its use is not restricted by any terrain and facility structure, which improves safety.
working principle
LT-800 high-voltage wireless nuclear phase instrument is composed of X transmitter, Y transmitter and receiving host. Two detection transmitters can determine whether the line is live, and then send out the measured phase and frequency signals. The receiving host receives the signals sent back by the two detecting and transmitting devices, thereby judging whether the two lines are in phase.
