Underground High Voltage Cable Fault Tester Fault Distance Locator
1 Year Warranty
Product Introduction
Most power cable of distribution system is installed in the ground
of city. Some of them will be failure after long time service. HYCF
is applied to detect the failure point of those power cables. The
cable can be test by HYCF include the low voltage cable (0~1000V),
high voltage cable (1kv~35kv) and communication cable. The fault
type of the power cable can be detected by HYCF include the
disconnection of cable, lower insulation to earth, lower resistance
or high resistance connected to earth and poor contacts of cable
connector.
High speed sample system and high bandwidth input circuit are
integrated in the tester to get the exact reflection curve of
signal so that the distance of fault point to signal sample point
can be calculated in high accuracy and high resolution. Special
sound location tester configuration can be applied to locate the
fault point more exactly.
1. High reception sensitivity
2. Low static drift
3. High positioning accuracy
4. Anti-interference ability
5. The LCD shows the signal and status
6. Built-in lithium battery and charger
