lEAKAGE CURRENT MONITOR

on-line assessment of surge arresters
A surge arrester may be inexpensive, but it has an important function protecting your transformers.
The LCM500 can measure condition while the arrester is still in service, measuring the quality of the
metal oxide blocks and helping manage the risk of failure. With the LCM500, it takes less than 15
minutes to establish that your surge arresters are healthy and the transformer is still protected.

Features
Portable

Battery-operated instrument for inspection of
surge arresters for condition assessment on a
regular basis.

Arrester ID

Unique identification of each surge arrester
makes data management easy. LCM500
can store 1000 surge arrester IDs and
measurements performed in the field.

Data Management

Secured through new Windows© LCM500
Software handling all your surge arrester
readings. Defines individual surge arrester
types including operational parameters.
Software includes possibility to perform
evaluation of groups of surge arresters e.g.
same type of arresters or alternatively for a
region.

Benefits
• Safe and effective assessment of t
metal oxide surge arresters
• Wireless sensors
• For non-invasive routine surveys of
substations
• According to IEC 60099-5 method B2
• Advanced user-friendly diagnostic tool
• Perfect for condition based
maintenance (CBM) program

Cost effective

Inspection of a surge arrester takes less than 15
minutes on location and can be performed with
the arrester in live operation (no disturbance of
power distribution).

Continuous Monitoring

The LCM500 can be used for short-term
monitoring of one arrester to investigate details
in leakage current changes versus time.
