16kV Surge Wave Tester

The High Voltage (HV) Surge Tester is a robust and dependable tool crafted to identify faults in underground power cables. It does this by utilizing the acoustic method alongside a compatible Surge Wave Receiver.

Beyond just pinpointing faults, the HV Surge Tester also enables the pre-location of cable fault distances when paired with a compatible pre-locator unit in Impulse Current (ICM) mode. For even more precise fault detection, it can be connected to an Arc Reflection Filter (ARM/SIM mode), which significantly boosts pre-location accuracy.

The High Voltage Surge Tester primarily locates underground cable faults using the acoustic method . It sends a high-energy electrical surge down the faulty cable, causing a spark and a loud "thump" sound at the precise location of the fault. This sound is then detected by a technician using a sensitive surge wave receiver, allowing them to pinpoint the exact spot for repair.
The Impulse Current (ICM) and Arc Reflection (SIM/ARM) modes, are used for pre-location, which significantly enhances the fault-finding process.Instead of blindly searching for the fault, these modes work with a pre-locator unit to estimate the fault's distance from the tester. ICM mode measures the characteristics of a current impulse generated by the fault's arc to calculate the distance. SIM/ARM mode is an even more precise technique that uses a special filter to capture the reflection of a low-voltage pulse from the high-voltage arc at the fault, allowing for a more accurate distance measurement. This pre-location process significantly narrows down the search area, making the final pinpointing with the acoustic method more efficient.
