| Specifications | Specifications - Capable of testing every fault of all kinds of power cables of 35
KV lower voltage grade with copper or aluminum core, such as faults
of open circuit, short circuit, splice, high resistance flash
aspect, and high resistance leakage aspect. - Electric wave propagation velocity of most common cables are
preset for convenient testing, such as polyethylene cable, PVC
cable, PILC cable, and XLPE cable. - Single button operation for auto display of far end and fault
distance in screen. - Test distance: 15-8000 m range (maximum 16 km testable from
bilateral ends). - Four types of wave sampling frequencies: 40, 20, 10, and 5 MHz. - Accuracy: within +/-0.2%FS, absolute error 15 m for cable 1 km
less, 20 m for 1 km over. - Differentiability: V/2f meter (V: electric wave propagation
velocity in cable, f: sampling frequency), For example, V=160m/s,
40MHz sampling frequency used for measuring, screen cursor moving
one unit of dot will mean 160/(2x40)=2 meters. - 5 inch dot matrix LCD for display of data and oscilloscope
graphics. - Measured length direct displayed after locating and moving the
single line cursor to point. - Menu help "Specialist System". - Measured data and chart can be stored. - Built-in printer for instant data recording. - Sizes and weight: 455x315x195 mm, 9 kg Integral Route Tracing Signal Generator - Generate 15 kHz sine wave signal - Output power not less than 30 watt - Vibration type: intermittent - Voltage 220 V AC +/- 10%, 50 Hz - Working ambient: -10 to 45 deg. C Fault Locating Receiver - Sensibility: Signal generator of 50 ohm sending 300 Hz signal,
point locator maintains non-distorted output of 2 V, input signal
not above 10 micro-volts at signal to noise ratio better than 20:1 - Task type selection: Point locating I: Signal received via 300 Hz filter amplifier Point locating II: Signal received via direct amplifier Route tracing: Route tracing and depth measuring - Input impedance not less than 1.2 k. ohm - Ear phone 2 x 2000 ohm - Working voltage: 9 V +/- 10% - Working current: locating 5 mA, tracing 7 mA - Working ambient: -10 to 45 deg. C - Sizes and weight: 455x300x180 mm, 8 kg |
