AL NT Cable and Phase Identification

Description

The AL NT Cable and Phase Identification Instrument is designed as safe and reliable tool for the field work. This unit combines all necessary functions for detecting the target cable out of a bundle of cables in trenches or cable trays and it will positively identify and match unknown phases for reliable network installation and operation. The AL NT is available in three versions to conveniently adapt to customer needs and is designed for rugged field use.

The new NT-impulse method was especially developed for comfortable and reliable identification in all types of de-energised cables and provides identification in energised LV cables.

Under certain conditions, the "twisted-field-method" offers advantages and therefore is include in all three versions and the corresponding Surface-Sensor is included in the standard scope of delivery.

Features

• High reliability due to online-communication of generator and receiver with digital NT-impulse technology
