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.

GDPD-PTU PD Online Monitoring System for Oil Transformer
The aging and damage of the internal insulation of the transformer mostly starts from local discharge. The reason for local discharge is that the electric field is too concentrated at a certain point, or the electric field strength at a certain point is too large. At present, the main methods for detecting transformer local discharge faults are: UHF ultra-high frequency monitoring method, HFCT high-frequency pulse current local discharge measurement method (pulse current method), ultrasonic local discharge measurement method (ultrasonic method), and oil gas chromatography analysis method.
