Requires design insolation tester ( megger) of 500v to automatedly test cable with 16 wires.
** please see the attached block diagram
Develop the tester ( like megger tester ) with ORCAD ( HW diagram), with all the components that can be found in digikey/mouser.
1. 16 wire are connected to the tester board.
2. Your insolation design controlled by microchip pic 33 (MCU).
3. It required to control by the MCU :
a. Which wire to test
b. Volts to test ( 30-500 V).
c. MCU shpuld read the insolation Results in volts to calculate (Mohms resistance).
(High voltage protection- for the MCU - is needed in case of shortcuts between the
** using multiplexer if preferred ( if not possible to test with 500V , I can consider testing up to 250V )
you supply all the source files.
