Elektronika - ECFL 30

FOUR INSTRUMENTS IN ONE

• Active bridge for accurate location of faults where the level of disturbing voltages are low
• Wheatstone bridge for location of faults where the level of disturbing voltages are high
• Graaf fault locator for accurate fault location on totally watersoaked cable
