Product Features
High voltage pulse gennerator XHHV535-2L
mainly used for shock discharge during low-voltage cable fault
testing. The pulse generator adopts humanized design operation
mode, high-precision dedicated high-voltage electronic components
and high-frequency high-voltage technology, which is easy to
operate, light in weight and easy to carry. It integrates the
energy storage capacitor, DC high voltage source, and discharge
ball gap. The operation of this equipment is safe and reliable,
with automatic protection functions of over-current, overvoltage
and overheating, it can truly achieve the effect of not being
damaged by impact, and it can also work normally with high voltage
to ground. Low voltage pulse generator is equipped with a time
relay, and the discharge time interval can be arbitrarily set
within 0-100 seconds. When working, the high-voltage pulse output
is uniform and controllable, high-voltage side voltage measurement,
make the result real-time and accurate. Unique high-voltage
measurement design, in the stop state, the voltmeter can indicate
the capacitor voltage in real time. The user can observe the
residual voltage while discharging, until the voltage value returns
to zero, and finally make the discharge more thorough.
cable fault pinpointer XHDD503C
Cable fault location instrument uses the acoustic and magnetic
synchronization method to determine the power cable fault point.
The electronic flashover is generated by the impact discharge
generator, picked up and amplified by the corresponding probe, and
the precise location of the fault point is determined by auditory
and visual judgment.
It is a device that completes the precise positioning of the cable
fault point within the rough measurement range and collects the
acoustic and magnetic time difference. It integrates positioning
technology, path-assisted testing and other technologies, providing
multiple test modes and rich and diverse prompt information to
efficiently and accurately complete cable fault location
