 Digitized AC and DC fault locating bridge, menu controlled, automatically balancing and with integrated functions for acceptance tests and screening tests.
- automatically balanced bridge
- for maintenance and series tests
- fault location measurements as per : Murray, Küpfmüller and Graf (Fischer)
- Measurement is possible even with residual voltages on test object of up to 40 V AC or DC
- measurements possible on loaded and unloaded cables
- input of cable temperature via test sonde RS 232 interface for printer or PC
- easy menu-driven operation
- main functions by fix defined keys
- storage of test results
- power supply by NC-accumulator, external 12 VDC or main supply
- in built charger, operation time 6-8 hours
- splash-proof with cover open, waterproof with cover closed
Fault locating methods:
|
Murray
|
with one healthy wire of the same kind (2-wire)
|
|
Graf
|
with any two healthy wires (3-wire)
|
|
4-wire measurement
|
in case of low-resistive loops
|
|
Küpfmüller
|
in case of a poor healthy wire ( i. e. manual switching at the far end)
optional extra: remote circuit closer
