LV Monitör
LV Monitor
The Teleflex LV Monitor has been designed for the location of all types of low voltage cable faults but especially the difficult and troublesome intermittent faults. It can be controlled locally from a portable PC by blue tooth or remotely over a telephone channel (either landline or GSM). Unlike portable available TDR fault locators, the Teleflex LV Monitor is connected simultaneously to all 3 phases of a live LV cable to allow the local or remote operator to perform TDR testing on any combination of phases. Power for the Teleflex LV Monitor is taken through the 3 phase test lead and the unit requires at least 1 phase to be energised.
The Teleflex LV Monitor includes a 4 channel transient recorder (3 voltages and 1 current) which is used to acquire information about the exact nature and behaviour of intermittent faults. The signals acquired by the transient recorder are also used to detect “trigger” conditions for the TDR system based on voltage distortion and/or over-current.
Recordings from 2 units can be used for fault location by transient travelling waves using a special synchronising feature.
By providing total control from a remote location the Teleflex LV Monitor can be connected to a faulty cable by field staff who are not necessarily familiar with the analysis of TDR waveforms – the expertise in adjustment and interpretation being provided by a centrally located specialist. This becomes particularly benefi cial when the equipment has to be left on-site awaiting the (re)-occurrence of an intermittent fault.
