Features:

Professional detuning function:

Designed for the problem of ferromagnetic resonance in the power system. It can monitor the open triangle voltage of the voltage transformer of the system in real time and accurately identify the resonance state.

Intelligent judgment and processing:

Using intelligent microcomputer algorithms to distinguish different types of resonance (such as fundamental frequency resonance, high frequency resonance, frequency division resonance), and automatically take corresponding detuning measures according to the resonance type.

Real-time display and recording:

With a clear display screen, it can display system voltage, resonant frequency and other parameters in real time, and record the time and type of resonance, which is convenient for query and analysis.

Advantages:

Effectively eliminate the harm of resonance:

Timely eliminate ferromagnetic resonance, avoid serious power accidents such as voltage transformer burning, lightning arrester explosion, busbar short circuit caused by resonant overvoltage, and ensure the safety of the power system.

Extend equipment life:

Reduce the impact and damage of resonance on electrical equipment, extend the service life of voltage transformers, switchgear and other related equipment, and reduce equipment maintenance costs.

Improve power quality:

Maintain the stability of power system voltage, reduce voltage fluctuations and distortion, improve power quality, and ensure the normal operation of the power system.

Application:

It is mainly used in power systems with ungrounded neutral points or grounded via arc suppression coils, such as substations, factory distribution rooms, etc. It is especially suitable for power environments with a large number of nonlinear loads that are prone to ferromagnetic resonance.
