GD-3134D+GD-2134L UHV Cable Sheath Fault Locator
GD-3134D UHV cable sheath fault locator is an intelligent instrument with innovative features and high performance that integrates computer technology and digital signal processing technology. The UHV cable sheath fault locator can measure the resistance current in the faulty cable in the wellbore through the current sensor and locate the cable fault point in sections. For cables laid on cable supports in large quantities in cable tunnels, the DC voltage can also be measured by high-voltage probes to determine the fault point.
The UHV cable sheath fault locator needs to be used in conjunction with the GD-2134L UHV cable sheath fault signal generator, which can provide high-voltage pulse signal source for the fault location of the UHV cable sheath, to complete the precise location of the UHV cable sheath grounding fault.
