Advanced Total Online Monitoring System For MCSG

It is an advanced orline diagrosis System lor metal cad switchgear that precidents any problems in advansed and maintenance by detecting partial discharge such as Corona, Rrc that is generated from degradation of internal system of a metal clad switchgear, thereby contributig to prevent eamages from system breakdown, electrical fire, etc and to assure system quality and largevity.
Characteristics of the System

• Insoects in spilte of any condition of a live wire
 Detects dedication of insulation and defective of contact in spile of any
 conditon of a live wire in MCSG
 Korea represenlalive diagnositc systems for MCSG
 Numercus field diagrosis experience
• Real Lime Measuring and Monitoring
 Online monitoring system (Every second data acquisition)
 Real frme Online data relrieval
 Dsplay a meassuting data through analysis SAW using web access
• Detects from broadband
 Effectively detect partoal discherge signar by selecting commercial cycle or
 high frequency and broadband (400~800MHz) in which noise is
 relativety low
 Transtion of degraction using patterns of radated electromagnetic wave
• Noise process
 Outside noise process through Auto Threshokl
• Communication methed
 Various communication method
 RS-485 / RS-422 / RS-232 / 4~20mA / Dry ccnlacl
