Multi-Electrode Spark Tester |
Description:
A multi-electrode or a multi-wire test system is designed to test simultaneously several insulated conductors of high-voltage cables per pass. The device can detect both open and hidden defects in the insulation. Structurally, the installation is a single high-voltage apparatus IASI-M or ASI-20V mounted on a mounting rack, high voltage from which is supplied to the ball electrode assemblies. Each electrode assembly has its own sensor and a breakdown counter with alarm, a drive lock relay. This allows you to track insulation breakdowns independently for each test conductor, and also to disconnect the traction drive in case of insulation damage.
The use of one such device for testing several veins simultaneously, can significantly reduce financial costs.
Functions:
• High voltage test of several cable cores at once • Smooth test voltage setting • Independent digital counter, breakdown sensor and drive lock relay for each core under test • Sound and light alarm during breakdown
