The variable output voltage can also be used for sheath testing at 5 or 10 kV. Fault Pre-location After identifying the type of fault, pre-location of the fault position can be determined using the following methods: ■ A TDR is used to pre-locate cable faults using pulse echo, arc reflection, impulse current (ICE). The MTDR100 features auto-ranging, auto distance to fault and operator assist functions that guide the operator through the fault locating process. ■ In the Arc reflection mode, faults are stabilized by creating a temporary "bridge" to earth. During this condition, a standard pulse echo measurement is taken into what is basically seen as a short circuit fault. ■ Arc reflection plus provides the operator the added advantage of being able to view and analyze up to 1024 traces (range dependent) taken during the period of the arc. ■ During Differential arc reflection mode unwanted and confusing reflection are removed leaving a clean trace with only the fault position, point being displayed by a positive pulse . This method is especially suited in locating high-resistance faults in complex cable systems. ■ Impulse current, or ICE, is a transient analysis method of pre-location utilizing the integrated linear coupler. Fault Conditioning Fault conditioning is used to stabilize unstable flashing or high resistance faults. The PFL22M1500 incorporates both&nb

PFL22M1500 Portable Cable Fault Location and High Voltage Test System Proof/Burn Following a breakdown of the cable under test, a high current is applied that stabilizes the fault condition. This allows easier and faster pre-location and pinpointing of the unstable faults. Pinpoint fault location Accurate pinpoint fault location is achieved using the electro-magnetic/acoustic method whereby the powerful 8/16 kV 1500 Joule surge generator (thumper) and a pinpointer (Megger digiPHONE+) is used.
