The SMART THUMP ST25-30 Portable/Vehicle-mountedCable Fault Locating System provides safe, efficient andextremely easy-to-use solutions for quickly identifying,prelocating and pinpointing various types of cable faultsfor power cables. The ST25-30 is developed to meet therequirements for typical medium-voltage distribution cablefault location markets from 11 to 35 kV system voltage.
Circuit parameters include:
- System voltage up to 35 kV (phase to phase)
- Insulation EPR, XLPE, PILC and mixed
- Typical conductor sizes between #2 and 1000 MCM(34 mm2 to 500 mm2)
- Circuit lengths from a few hundred feet up to a maxof 170,00 ft (52 km)
APPLICATIONS
The SMART THUMP ST25-30 represents a newgeneration of advanced underground cable fault locatingsystems that require less training than a traditionalthumper-only system, while providing the big advantageof displaying the distance to fault. It is the only faultlocator with built-in intelligence to interpret the resultsof the initial test sequence. The "turn & click" rotarybutton operation lets the user automatically proof test,pre-locate, and pinpoint the fault from one convenientcontrol console. No adjustments are typically required.If the user selects, the unit automatically sets the thumpvoltage to minimize the stress applied to the cable. TheST25-30 features an automatic safety check to protectthe user from incorrect or faulty connections (F-Ohm).The heavy-duty wheels of the unit are ideal for use inrough terrain. The IP53 rating allows operation in wetenvironments. The ST25-30 can also be permanentlyinstalled in a vehicle (truck mount version).
