Dear all,
I am trying to build 3 phase voltmeter that could measure L-L and L-N voltage during 3 phase 3 wire and 3 phase 4 wire connection. 3 phase 3 wire and 3 phase 4 wire connection are external connection.
as we know in 3 phase 4 wire we will get neutral reference so we can get...
Hi,
I am trying to detect any appliance being turned off or on. I am using SCT013-30 (30A/1V) sensor with 62 ohm burden resistor built in. If I measure the AC voltage with just the sensor (not connected to my circuit, I get 30mV for off and 340mV for on.
As soon as I connect the circuit to PIC...
