LCM II의 적용

The LCM has been used since 1989 to determine short term as well as long-term measurements on arresters from 66kV to 765kV networks, and is today delivered
to power companies and utilities in about 50 different countries.

Performing Field Measurements

LCM can only be used for arresters on insulated base and with a separate earth lead.

Arrester ID is downloaded from PC software to LCM II instrument prior to performing inspection of surge arresters. LCM II can store 1000 arrester ID’s.

On location choose correct arrester ID and perform measurement. LCM II can store 1000 measurements performed in the field.

After completion of field measurements stored data are transferred from LCM II instrument to PC software. You are now ready to perform analysis and plan your next inspection.

General overview of LCM II condition monitoring system.

LCM II - The Technique

Well-proven and acknowledged monitoring technique using third-order harmonic analysis with compensation.

Rated according IEC 60099-5 as the best field monitoring technique for Metal Oxide Surge Arresters (MOSA).

LCM II records operating voltage and temperature during field measurements.

The LCM II measurements are automatically normalized to standard ambient temperature (+20°C) and 0.7x rated arrester voltage based on recorded temperature and operating voltage during field measurement. Measurements performed under different conditions can thereby easily be compared.
