Bus protection panel
The bus has a low frequency of failure, but in the event of a failure, its scale and range is very large because the bus is connected to a number of transmission lines, transformers, etc. Therefore, the bus protection system needs a relay method that is highly stable in terms of its roles and reliability. YPP's bus protection panel combines General Electric's UR series and YPP technology to produce and supply stable and reliable products.

Power transmission line protection panel
Transmission lines are installed in a wider area than other electrical equipment, so they are easily affected by external natural conditions and have a very high frequency of failure. Therefore, they must be operated in sufficient coordination with other protection devices. Our transmission line protection panel is provided with General Electric equipment and high-quality technology to quickly and accurately eliminate failures in transmission lines and ensure high reliability to operate in sufficient coordination with other protective relay devices.

Transformer protection panel
The transformer is very important for stable and efficient power transmission to consumers because it performs a function of lowering high generator voltage to the distribution/load network through the transmission network. We provide stable technical services based on our technology and know-how amassed over long years of experience, along with high-quality General Electric products.

Circuit breaker operation failure protection panel
The power system consists of a main protection system and a backup protection system for use in the event of system failure, to stably and quickly separate the failure part; however, if the circuit breaker is inoperable and it is not possible to separate the part in which failure has occurred, a circuit breaker adjacent to the inoperative circuit breaker should trip and rectify the failure. To this end, we provide a circuit breaker failure protection system with proven YPP technology and General Electric products, which ensures high stability and durability.

Special protection panel
SPP is designed to prevent failures in electrical equipment from affecting the entire power system. It calculates the maximum current for continuous power supply in a stable system, and prevents excessive instability of the power generation stage and voltage instability of the load stage. We provide a highly reliable system based on General Electric's high-precision digital protection relay and YPP's technology.

Fault recoding panel
The fault recoding panel is used to record and analyze any abnormalities occurring in the power system and to analyze the cause of faults and the operating status of the system, ensuring accident detection and stability and reliability of the power system operation function at the power transmission/reception end. YPP's fault recoding system automatically analyzes abnormal conditions and a range of fault-related information based on its highly advanced technology along with the high reliability of Ametek. It monitors and records faults and the operation status of various protection devices and has the ability to monitor voltage, current, active power, reactive power, phase, frequency, and harmonics.
