XHDD503 Underground Cable Fault Pinpointer
Description
Developed independently by our company, the XHDD503 portable
underground cable fault locator utilizes highly mature
acoustic-magnetic synchronization detection technology, which has
been refined over more than 50 years and is widely accepted by
industry users. This compact and lightweight device comes in a
protective PVC case for easy portability post-detection. It
features a microammeter display and adjustable knobs for electrical
level, frequency, and volume. Observing the microammeter pointer's
swing allows you to monitor the magnetic field strength during
flashover discharge at the fault point. The electrical level knob
can be adjusted to set the magnetic field strength reference.
During path detection, the frequency knob can be tuned to make the
path signal more recognizable. When locating faults, the frequency
knob can be adjusted to avoid radio signals, and the volume can be
regulated to ensure clear sound signals.

Product Features
1. Synchronously receive vibration waves, sound waves and
electromagnetic waves generated during discharge at the fault
point;
2. The acoustic and magnetic channels are designed separately and
powered separately, with stronger anti-interference ability;
3. Super magnification, detection depth is greater than 10 meters;
4. Ultra-low and low-power design, quiescent current is less than
10mA, and continuous operation is more than 20 hours;
5. Analog meter design, signal strength and trend are clear at a
glance;
6. Zero level can be adjusted arbitrarily, suitable for various
strong and weak scenes.
