In transmission line protection panel, there is a function that uses PCM current differential function(87T) and back-up function which uses 3 steps(zone 1, 2, 3) distance protection scheme.

In a Power System, substation is an assembly of technology and facility that carry out major functions such as distribution of power, up-down transform voltage and protection and control of system.

Protection relay needed for protection of transformer has current differential function as main protection.

Utilizing the overcurrent protection function for circuit breaker status monitoring and enabling operation through breaker operation command detection (BFI).

For power system stability such as frequency, active/reactive power, and various other protection elements are used.

A fault recording panel is used for analysis of trouble’s cause and operation status of system.

Mini-RTU panel guarantees an economy and flexible application depending on a purpose of a facility, done by applying a concentrated min-RTU.

GIS is concealed facility that has switching facility such as circuit breakers, disconnection switch and transformers, arresters and busbar etc, in metal tanks. its charging part is supported by a Spacer.

It performs control and status monitoring of circuit breakers, disconnectors, and ground switches remotely. Additionally, it allows for synchronization check through PT inputs at both ends before the circuit breaker insertion. It acquires current and voltage values from CTs and PTs, enabling monitoring from the upper remote system.

A special protection system maintains power system’s stability when a serious fault occurs in power system and constantly supplies power by estimating a maximum current.

Shunt Capacitor Bank is generally used electric power facility that enhances an efficiency of power transmission. constantly maintains a voltage of power system through compensation on reactive power.
