Features
Tester IVZ-2010 is manufactured on the modern element base and with using the special program
that provides reliable operation when finding the intertern and housing shorts for various types
of electrical machines with operating voltage up to 10 kV.
It can be DC and AC machines of any size and wide power range, as well as generators of various modifications and purposes. In order to work with a variety of electrical equipment the special devices have been created, which make
it possible to expand the versatility and range of application of this device.
Description
The device provides a controlled output of a short-time signal (up to 10 μs at a frequency of 10 Hz) of high voltage (from 100 V to 3 kV), and further the processing of the current signal.
Indication of the processing result to the user interface is provided in two ways - on the LCD screen and using LEDs.
By comparing with the standard the device provides detection and localization of faults in the windings of electric machines.
The device operates on one of the selected measurement schemes, using appropriate tools :
- Two-wire cable;
- Double electromagnet;
- Double probe;
- Electromagnetic staples;
- Rod electromagnet;
- other.
