Protection panels and automation devices spanning EHV transmission to distribution networks. Every product is developed and supplied in-house, built on field know-how gathered since 1997.
From transmission and substations to distribution, we cover protection and automation of power equipment under one roof. Protection panels and IEDs, substation operating systems, distribution automation units and switchgear are designed and built in-house.

The Digital Substation Automation Operation System is an HMI (Human Machine Interface) system that presents operating information on each facility in an IEC 61850-based SA (Substation Automation) digital substation to the operator.
Distance and current-differential protection for 154 kV and 345 kV transmission lines. The equipment with the highest fault frequency is protected by IEC 61850-based IEDs. KEPCO supplier qualification for 154 kV (2012) and 345 kV (2016).
Ratio-differential, overcurrent and earth-fault protection for 154 kV transformers. KEPCO supplier qualification in 2013.
STP-K120SBP-K110-CUSBP-K110-BU
Current-differential protection for 154 kV and 345 kV buses in a distributed architecture of central unit (CU) and bay units (BU). NEP certification in 2020; KEPCO qualification for 154 kV (2017) and 345 kV (2018).
Detects 345 kV circuit-breaker failure and provides back-up protection, including 1.5-CB schemes. KEPCO supplier qualification in 2016.
Records fault waveforms and power-system dynamics. Two fault recorder panel types qualified by KEPCO in 2018.
FRTU(Pole-Mounted)FRTU(Pad-Mounted)
Feeder remote terminal units (FRTU) for remote monitoring and control of overhead and underground distribution lines.
Extra High Voltage SwitchgearHigh/Low Voltage SwitchgearMotor Control Center(MCC)Power/Distribution BoardDistribution Switchboard
From extra-high-voltage, high/low-voltage panels, MCC and power/distribution boards to station service switchboards, designed and built in-house.
Founded in August 1997. Protection panels, IEDs and distribution automation devices are designed and built at the Incheon headquarters and the Naju plant, and verified in our own test laboratory.
We speak through registrations and certifications rather than brochures. KEPCO supplier qualification and NEP certification are granted per product type after testing.
Recently published catalogues. Product catalogues and panel mounting drawings are also available on each product page.
We design and test protection relays and substation automation equipment ourselves. Applications are accepted by email. Work locations are the Incheon head office and the Naju plant.
