I need the design / schematic for a composite instrument in order to measure insulation and dielectric strengh. megaohmeter section: - measurement voltage: programmable, from 100V to 3000V dc - insulation resistance range: 200Kohm to 200Gohm autorange - 1% accuracy dielectric strengh section: - testing voltage: to 6000Vdc, 3% accuracy - maximum current 5mA - current measurement: 1% accuracy the two sections must share the high voltage generator part only the analog part is required (voltage and current generation, amplifiers...), i will complete the instrument with the microprocessor part, providing the necessary analog and digital I/O

Greetings, Thanks for inviting to bid. Have gone through your requirement. The design is quite involved simply because of the voltage and currents you have to deal with e.g. when measuring Gohm the current would be sub nA. I have experience working on the sub nA range Analog circuits, however haven't done much work on kV designs. The overall requirement is clear and should be achievable but would require significant design effort. I understand you would be needing only the Analog part of the circuit but we will have to consider all factors which you need to take care while fabricating the design as well as the digital control aspects. Would like to discuss some more technical details, time line and budget - as it may not be feasible in this budget. Look forward to hear from you. T & R Alok Pugalia
