TTU301 Smart Distribution Transformer Terminal Unit

TTU301 Smart Distribution Transformer Terminal Unit

Overview: Smart distribution transformer terminal unit is installed in the transformer station area. It has the functions of power distribution energy metering, reactive power compensation, three-phase load unbalance treatment for 0.4kV low voltage equipment of distribution transformer and automatic measurement, acquisition, protection, monitoring and safety protection for power supply demand information .

Overview: 


The TTU301 is installed in the station area of pole mounted transformer, which has the functions of power distribution, energy metering, reactive power compensation, three-phase load unbalance management, and the automatic measurement, acquisition, protection, monitoring, safety protection, etc. of power supply and consumption information for 0.4kV low voltage equipment of distribution transformer.


Features:

 

l Distribution transformer monitoring: Real-time collection and uploading of voltage, current, temperature and humidity data in the station area

l  Automatic meter reading: Data collection of total meter in station area, to obtain the refined operation data of station area, the extendable broadband carrier reads the user’s meter data.

l Equipment monitoring: Automatic monitoring of equipment such as feeder switches and leakage switches in the station area.

l Intelligent reactive power compensation monitoring: Real-time data collection of intelligent reactive power compensation equipment.

l Micro-power wireless maintenance: Due to the complex environment of the installation location of the box, the terminal provides convenient on-site wireless debugging and upgrade.

l Three-phase unbalance management: Perform balance adjustment using commutation device according to the monitoring of three-phase unbalance situation in the station area.

l Fault location and indication: In-situ indication and automatic report by monitoring information such as its own status, external switch faults, etc.

l Safety protection: Information safety protection based on embedded security chip.
