Used to test the continuity of paint film of enamelled round wire with nominal diameter of 0.050mm or above and 1.600mm or below (i.e. the number of pinholes per unit length of enamelled wire sample).
It is suitable for measuring the speed of switches produced by switch factories at home and abroad.
In addition to measuring ground resistance, low resistance conductor resistance, soil resistivity and alternating current voltage can also be measured.
This equipment has a 6 phase voltage and 6 phase current shaft, which is suitable for various types of relay protection device test.
It can complete most of the field test and verification work, can verify all kinds of relays and microcomputer protection, and can simulate all kinds of complex transient, permanent and transformational faults for whole group tests.
It is suitable for power department, power department of factories and mines, scientific research unit, railway, chemical industry, power plant, etc.
It is not only suitable for the measurement of inductive test products such as transformers, transformers and reactors, but also suitable for the measurement of resistive test products such as copper bars, wires and switch contacts.
The test data is stable and reliable, the Chinese character LCD screen, the operation is intuitive and simple
Built-in printer, easy to print and save test data
KD7440 program controlled voltage tester provides ground resistance, insulation resistance, AC voltage resistance, DC voltage resistance, normal contact current (dynamic leakage), fault state contact current (static leakage), low voltage start, power and other testing functions.
It can detect all kinds of insulation faults, DC cross-channel faults and AC cross-channel faults in DC systems of various voltage levels (24V, 48V, 110V, 220V).
