SERIES BOX TRANSFORMER INTELLIGENT RTU

NRT-33X box type substation intelligent measurement and control device can protect and remotely monitor the box type substation, and fully realize the "remote signaling, telemetering, remote control and remote adjustment" functions for wind power or photovoltaic box type substation; Realize the operation management mode of "fewer people on duty" for wind power or photovoltaic projects.

POWER QUALITY MONITORING DEVICE

Measurement and analysis of the AC power quality from the public power grid to the client, includingvoltage deviation, three-phase voltage imbalance, Harmonics in Power Grid , Interharmonic.Using wavelet transform to analyze the harmonic of non-stationary time-varying signal.Measurement and analysis of the power quality of various electrical equipment to the public power network under different operating conditions.Load fluctuation monitoring: regularly record and store power parameters such as voltage, current, active power, reactive power, frequency and phase.Characteristics of on-line, multi-parameter, large capacity, high precision and application of signal analysis theory make LZ-300B widely used in transmission and distribution, power electronics, motor drive and other fields.
