3 phase circuit phase detection and voltage measurement

From 00:14

Instant confirmation

From 00:18

Old approach

From 00:23

Check the phases.

From 00:29

Now check the three phase voltages.

From 00:34

Step 1: R (1) - S (2) line voltage

From 00:44

Step 3: T (3) = R(1) line voltage

From 01:00

Check phases and voltage values at once.

From 01:03

What's more, the clamp sensors are affixed outside the wires insulation for maximum safety.
