1. VITZROTECH IED & Controller(Digital Protection Relay & Control Meter) INTRODUCE

 

 1-1 Digital Protection Relay _ VIPAM SERIES 

 

  ● VIPAM SERIES IED (Integrated Electronic Device) is a digital protection relay that

      enables a high-precision measurement and protection relay for switchgear power 

      equipments. The switchgear panel became compact by connecting various protection  

      functions with DSP algorithm and high-speed logic function to enable a flexible  

      engineering. It is the IED with variety of interfaces with the upper system resulting in  

      an electronic distribution panel solution. 

 

  ● 7”TFT-LCD(HD) is used to check diverse information, the machinery operation and

      setting are simplified, providing Korean or English and operators can easily use the  

      device with an intuitive operation method. Especially, the existing communication  

      method (MODBUS, DNP3.) and an international standard, IEC61850, essential for the  

      smart grid configuration are adopted so that it can be applied to all facility equipments  

      and for improvement and repair. The network is redundant and high-speed data  

      transmission between IEDs is realized for the reliability of communication. 

    

  ● A management program is used on PC for IED value setting, logic design, value  

      monitoring, output control and so forth. RS232 port in front of VIPAM SERIRES  

      uses PC HMI software to support additional services including the device setting,  

      measurement, power monitoring and saving /modifying/recovering values  

      [relay factors]. Also, Fault Wave Data to analyze relay-relevant information can be  

      checked.
