VMS (Vibration Monitoring System)

Product Details System that systemizes the vibration analysis technology & knowhow of power plant, grafts intelligent prediction analysis, detects the failure or problem of main facilities earlier to prevent a severe accident by monitoring the condition of turbine & main rotating devices in real time.
Main Customer KHNP
Korea East-West Power Co., Ltd.
ENEC
Technical Specification This is designed to enable to replace on online even though there is failure or defects.
Online & offline diagnosis programs and handing manuals for failure checking and performance test are prepared so that it can give a help to operator’s proper handling and checking of failure.
All provided equipment is a product applied the best quality and up-to-date technology. All electronic parts have module structures having rich compatibility.
All equipment has an application history.
This system has a life and durability that endure continuous commercial operation more than 10 years, and can supply parts that require replacement from abrasion or deterioration and can support technical assistance.
For HMI graphic, it is required to discuss in advance with a purchaser.
It is possible to operate under the ambient temperature of -45℃ ~ 85℃ and humidity of 5% ~ 95%, which is the environmental conditions in a control room of power plant.
Product Specification -Input Chanel: Analog input 8CH, Tacho 2CH, 1Rack=48CH
