Isolation Transformer
Part 1

The following demonstration is very dangerous because of LIVE electricity !!!

Isolation Transformer The Isolation Transformer is rated as 2000W; therefore, the Soft Start Circuit Board is used. Moreover, the EMI filter can block the noise and keep the A.C. as near 50Hz as possible.

Switch on ... the testing light is on ... the most important thing is ... ... my home's MCB is not tripped.

Digital Volt Meter The input Voltage ... 228V , Current is not tested at this moment.
Digital Multimeter The output Voltage is 226V ... Don't worry ... since both voltmeters are not calibrated.
The video shows the output wave form of the Isolation Transformer from cold-start and switch off.
