Cable dielectric loss tester
Značilnosti izdelka
Meet the standards :KDHVA-60 meets IEEEP400.2/D9-2010 can be in accordance with the national standard for 10kv cable withstand voltage test;
Multi-purpose: the instrument itself integrates with IEEEP400.2/D9-2010 voltage test and dielectric loss factor diagnosis module. It can carry out a variety of tests such as cable AC and DC withstand voltage test, outer sheath test and fault location.
Voltage can be upgraded: The peak voltage can be increased to 45kV according to user needs, which can meet the test requirements of higher voltage cables.
Powerful output: the peak output voltage can reach 45kV, and the effective value can reach 38kV. Compared with the same category of instruments, the maximum capacitance is 10uF, which can test longer distance cables. Output current up to 60mA, and greatly reduce cable charging waiting time;
Unlimited running time: The high voltage generator’s running time is not limited by heat,
visualization software can be continuously run: all test results can be downloaded, edited and reported via USB or Bluetooth. The software has a graphical analysis function, which can read the test results more intuitively and generate a comparison with the previous test results;
Safety system: The instrument has two independent grounding devices (electronic and mechanical discharge), even if the power supply is accidentally cut off when the instrument is running, it can discharge the instrument to ensure the safety of the operator;
Return voltage protection: prevents personnel from being injured when the cable is powered on unexpectedly during the test. When the instrument detects that the external voltage is greater than 100V, it automatically cuts off the power supply and has a red indicator light to ensure the safety of the operator;
Easy transportation: It has outstanding characteristics in terms of size and weight (36kg), and has a very strong watertight housing with IP67 waterproof grade, reducing additional transport boxes for easy field testing and transportation;
Močna sposobnost proti motnjam: with high-definition color display (4,3 palcev), you can easily read the test results, in serious interference conditions F, the LCD screen last data can be stable in the +1 word range, stable reading, dobra ponovljivost. The system can be upgraded: the peak voltage can be increased to 60kV according to the needs of users, partial discharge test module can be added, and cable voltage resistance, partial discharge, and media loss factor test can be carried out at the same time
