(1) Problem Definition / Development Background

Lightning arresters protect power equipment from abnormal voltages caused by lightning and system surges.
If a lightning arrester degrades and fails, it can lead to thermal runaway, explosion, ground faults, and power outages.
Conventional diagnostic methods often rely on indirect third-harmonic measurement, which can limit diagnostic accuracy.
Substations need accurate, easy-to-use, field-ready diagnostic equipment for condition-based maintenance.

(2) Value Proposition / Solution

SURGETEC measures resistive current directly, which is a key factor in lightning arrester failure.
The solution enables early detection of degradation and supports preventive maintenance.
Users can diagnose arrester condition by simply attaching a CT clamp.
The system provides diagnostic values in approximately two minutes, helping operators make faster maintenance decisions.

World’s First Technology: Direct resistive current measurement method for lightning arrester diagnostics.
No Voltage Signal Required: Measures resistive current without separate voltage measurement.
Fast Field Diagnosis: Simple clamp-type operation enables diagnosis in about two minutes.
Empirical Diagnostic Standards: Diagnostic ranges are built from substation data in Korea and overseas.
Global Standard Alignment: Designed to support IEC-based safety management and country-specific voltage criteria.
Certified Innovation: Holds NET certification, Innovative Product designation, KEPCO Trusted Partner Certificate, and CES Innovation Award.
