Product Description

For the assessment of in-service surge arresters

The Doble LCM500 Leakage Current Monitor can measure condition while a surge arrester is still in service, measuring the quality of the metal oxide blocks and helping manage the risk of failure.

A surge arrester may be inexpensive, but it has an important role in protecting your transformers.

With the LCM500 surge arrester test set, it takes less than 15 minutes to establish that your surge arresters are healthy and the transformer is still protected.

• Portable, battery-operated instrument for regular condition assessment of surge arresters
