[INQ. NO. 1910E36] The substation total diagnostic system prevents breakdowns in advance by comprehensively analyzing acquired information online from a number of sensors for partial discharge, dissolved gas, bushing diagnosis installed in transformers and GIS and the operation information collected via the SCADA system. It runs multiple diagnostic functions as a single program and real-time, trend analysis works to check substations’ 
comprehensive state. Furthermore, the substation total diagnostic system has a convenient maintenance function in case of failure with individual system configuration and uses IEC 61850 communication protocol. Various diagnostic techniques and libraries to improve diagnosis rate are also available.
GLU Products have two different configurations, which are UHF partial discharge and CB operation characteristics. Partial discharge features an installed fUHF sensor (500MHz~1500MHz) enabling the user to make decisions on over five types of partial discharge. Data analysis of PRPS and PRPD with library update and measurement data learning function is also possible. CB operations have a trip / close function with coil current from 0 to 5A and open/close contact function. UHF partial discharge system of MLU (transformer) uses a window sensor and a drain valve sensor (300MHz~1,800MHz). It can make decisions on over six types of partial discharge and contains all the functions that GLU has. Furthermore, MLU has a dissolved gas analysis system, OLTC monitoring function and bushing diagnosis function with less than 0.2% of error rate.
During system runs, the single line diagram shows the location of sensors installed at substations, diagnosis state and communication state with symbol. The substation total diagnostic system shows the location and state of the sensor, diagnosis results of current facility in detail and shows the event history, alarm history and trend, check with details on users’ favor by various menu channels.
Monitoring events and alarms are possible and selected events display the state by vector diagram. Measuring value of gas type and indicate the abnormal state are also possible with using dissolved gas analyzing menu channel. Finally, the substation total diagnostic system shows a trend graph for each item so that the user can see the change of the transformer state at a glance over a period of time.

Once a neck or back pain occurs, there is a lot of difficulty in treating it permanently. The best way to prevent pain is to work in a correct posture and manage it before it occurs. To this end, the dentists’ associations of advanced countries such as the United States recommend the use of loupes.
The JTL Flip-up type adopts an ergonomic design to make the wearer’s sense of wear to feel no different from ordinary glasses, and the functionality is enhanced by the hospitals’ favorite protective goggle design.
market. Particularly, as a specialist in this field, the company operates a well-organized production system for the small quantities of various models with best quality, which customers are very satisfied with.
When a person approaches or steps on the mat, the sensor detects it and the dust collector operates and generate a vacuum. Much of the dust is sucked in from the stepping area, automatically stops operating after the person passes the mat and all the harmful substances that are sucked inside the mat are collected in a dust bag inside the dust collector.
The automatic valve of the mat applied with the flow path technology inflows surrounding air into the mat when the dust collector is operated and sucks unpurified external air and has an air purifying function to purify the surrounding air by discharging the purified air primarily through the dust bag and secondly through the HEPA filter to make the interior much cleaner and more comfortable, in addition, the BLDC motor can be used for a long time (4,000 hours) and for longer periods, which is superior in economic terms.
AIR MAX-Clean mat is durable due to no wear of its bearings and does not lose suction power even for long time use and is easy to manage. It can also be manufactured in the desired size, such as for clean rooms, access floors and gates.
At the same time, PACSPLUS has a useful tool to easily interface with every single HIS Hospital Information System (H.I.S.) Vendor’s application.
As the market’s needs for web-based solutions are sharply increasing, PACSPLUS also has developed 100% HTML Web-based PACS that is a Zero footprint viewer without any installation. Once a customer in a hospital is allowed to access the PACSPLUS Server, a hospital’s user can log into the PACSPLUS Web viewer through Chrome, Firefox, Safari, and Internet Explorer. Mobile PACS Viewer can also be accessed through both Android OS, and iOS Devices. Moreover, when a new project is designed, the user friendly interface has been always considered.
It measures the levels of CO2, VOC (Volatile Organic Compounds) and Particle Matter (PM2.5 & PM10). In addition, it measures temperature and humidity in your surroundings.
The sturdy and design-focused outer casing looks great while protecting your Huma-i device. Have peace of mind when carrying your Huma-i device during your activities.
As the product is tripod-shaped, any types of objects placed within the range of the tripod can be sterilized. And, it is also possible to widen the sterilization scope by extending the legs of the tripod. Anyone can easily and simply use the sterilizer as it starts working and automatically stops three minutes after the sterilization. All that the user has to do is to place an object within the tripod and press the power button on top for sterilization. In addition, it can be used as a cradle and a camera tripod by attaching the head cap.
With three UV-C germicidal lamps grafted onto each of the legs, the sterilizer has enhanced germicidal power. Moreover, test results conducted by the nation’s official test certification organizations including Korea Testing & Research Institute (KTR) and Korea Conformity Laboratories (KCL) show that it is capable of 99.9-percent sterilization.
Korea Electronics Technology Co., Ltd. continues to develop itself into and make challenges to become a respected global company with its own convergence technologies with electronics and machines and mechanism-based smart devices.
Moreover, the product is being well-received not only in Korea but also in many other countries around the world, winning the Grand Award in the International Invention Innovation Competition in Canada, the Gold Medal at International Exhibition of Inventions held in the USA, Russia, China, Poland and Taiwan; and the Silver Medal at the International Exhibition of Inventions held in Switzerland.
