Hi all,
Please give some idea for an interlock where the system can only be switched ON if it is properly grounded. The system is portable and a contractor is used to switch the system ON and OFF.
Thanks
A good isolation transformer will isolate the noise from the supply, you need to reduce the capacitance between primary winding to shield / ground similar to the principle for using 100nf capacitor in the supply lines. This will ground the noise.
Hi all,
One of the two volts reading is fluctuating too much, I am using 16F877A for measuring AC volts. I have used step down transformer 400 : 5 V and a10k preset to further reduce to 2 V, which is fed to precision rectifier using 2 lm301, this reading is fluctuating while in other I have...
Hi All,
This is my first post, I am new to micro controllers, have made a multi channel voltmeter using 16F877A and microcosm pro. I would like to eliminate leading zeros, i.e. my vm is 0 to 400 V, when measuring 50 V the display must be 50.0 instead of 0500.0. Can I get any suggestion .
