Distribution Transformer Monitoring RTU

General Description

SN-Pl distribution transformer monitoring RTU adapts high performance 32-blt RISC hardware platform and high accuracy energy measurement technology. Combining with the advanced Ethernet technology, GSM/GPRS/CDMA mobile telecommunication technology,the RTU has the advantage of powerful functions,simple manipulationstable operation and easy maintenance.
Functions
RTU hardware module; The RTU is combined with main control modulemeasuring moduleanti-tamper module,data communication unit module. The data communication is compatible with Ethernet module and GPRS/CDMA mobile communication module and support Hot-swap.
Software design module: The software of the RTU adapts embedded module programming modes and each module operates separately to facilitate Increase or deletion of function modules.
Reliable power Is used to avoid crash of data communication module.
Electricity meters of different protocols can be connected to the RTU at one time.
High accuracy sampling technology. SOC measuring chiis adapted to ensure accurate and reliable of the data.
Prompt report for the abnormal events.
Large capacity Data Flash and embedded file management technology are adapted,the storage capacity can be extended to 32MByte to ensure safe storage for long history data.
Automatic remote upgrade of application and communication protocol is supported to satisfy function extend In the future.
Data compression and encryption technology are used to guarantee data security.
Phase voltage,current ,power,power factor,maximum demand and harmonic content of voltage or current of each phase can be displayed.
Multi-tariff energy measurement, bi-direction active energy measurement, four quadrant reactive energy
measurement are supported and multi-tariff measurement for maximum demand Is supported as well.
Reactive power over-compensation value and reactive power lack compensation value can be calculated.
