Surgitech

What Surgitech does

Surgitech (서지텍) is a South Korean private company founded in 2019 and headquartered in Daejeon that develops electrophysics diagnostic technology and equipment for metal-oxide surge arresters (MOSA). The company has commercialized a proprietary phase-detection method that directly measures resistive current — the failure indicator in surge arresters — from total leakage current without requiring voltage application, in compliance with IEC standards. Its product family consists of three portable resistive current analyzers (RCA2000 professional, RCA1500 general-purpose, RCA1000 entry-level) that classify arrester condition as normal, caution, or defect and generate diagnostic reports with harmonic analysis up to 540 Hz.

Surgitech's primary customers are state-owned and private power utilities and electricity companies in markets with high lightning incidence, including Korea Electric Power Corporation (KEPCO), Danang Power Company (DNPC) in Vietnam, and Perusahaan Listrik Negara (PLN) in Indonesia. The business model centers on hardware sales of diagnostic equipment, supplemented by training and professional services, with quote-based pricing and multi-year contracts. The company pursues an enterprise field-sales motion anchored on KEPCO partnership (revenue-sharing agreement through 2026), KOTRA export programs, regional distribution partners (NSM Technologies in India, K-WE Co. in the Philippines), and government procurement channels. Government endorsements include NET (New Excellent Technology) certification, K-Innovative Product designation, KEPCO Trusted Partner status, CES 2023 Innovation Award, CE marking, and selection for the Super-Gap Startup 1000+ Project.

The company's commercialization is in early innings: revenue is not publicly disclosed, headcount is undisclosed, and the only known direct equity investment came from KAIST Technology Holding Company in December 2020. Strategic emphasis through 2025–2026 is on geographic expansion across Southeast Asia, the Middle East, and the United States, supported by government grants and trade-mission participation.

Core offering

Surgitech manufactures and sells portable Resistive Current Analyzer (RCA) equipment that directly measures the resistive current in metal-oxide surge arresters (MOSA) using proprietary phase-detection technology compliant with IEC standards. The product family — RCA2000, RCA1500, and RCA1000 — enables power utilities and government energy agencies to perform field diagnostics and condition-based maintenance on high-voltage surge arresters instead of relying on periodic replacement. Revenues are generated primarily through hardware sales, with ancillary professional training and support services.

Product overview

Surgitech (서지텍) is a specialized manufacturer of lightning arrester diagnostic equipment, offering a product family centered around Resistive Current Analyzers (RCA series). The core product line consists of the RCA2000 (professional-grade portable analyzer), RCA1500 (general-purpose portable analyzer), and RCA1000 (entry-level model), all based on the company's proprietary phase detection technology for measuring resistive current in Metal-Oxide Surge Arresters (MOSA) according to IEC standards. These products enable predictive maintenance by directly measuring the resistive current component, which is the primary failure indicator in surge arresters, allowing operators to identify deteriorating arresters before catastrophic failure occurs.
