3 Phase Sequence Presence Rotation Tester Indicator Detector Meter with LED and Buzzer 60V~600V (3 Phase AC)

3 Phase Sequence Presence Rotation Tester Indicator Detector Meter with LED and Buzzer 60V~600V (3 Phase AC)

Q: Will this work on the output of a VFD?

Matthew, a vfd is a Variable Frequency Drive. they are used for phase shifting and/or voltage shifting. my father uses one to convert his 220 single phase to 480 3 phase for his mill in his home garage.

Q: Misplaced instruction. what color lead goes on line 1, line 2 and line 3? thanks

It actually doesn't matter as long as the phase sequence is right. Convention identifies each of the 3 leads as L1, L2, and L3. Your equipment will have terminals labeled as L1, L2, and L3. You would assume L1 goes to L1, L2 to L2 and L3 to L3. This is correct. However, you can also connect L1 to L2, L2 to L3 and L3 to L1. Surprise, you can connect L1 to L3, L2 to L1 and L3 to L2. Each of the 3 variations gives the same result and is correct. What does matter is the sequence. Each line will cycle to peak voltage in rotation. Thats why this is a Phase Sequence Rotation Meter. First L1 goes high, then L2, then L3. If you start with L2, then L3 and L1, each goes high in Rotation. Typically, equipment (a motor perhaps) expects to see "Clockwise" Rotation, sometimes called "Right Hand" Rotation. Should you wish to reverse rotation (for a motor) swap any 2 leads and you get "Counter Clockwise" Rotation, sometimes called "Left Hand" Rotation. Sometimes, one of the leads will register a slightly higher voltage to common/ground than the other two leads. This "Hot Leg" assists with starting a motor. Usually you need not pay any attention to this. Your equipment manual will tellyou if you do. Convention will call for the Hot Leg to be L1. So, hook up your tester, without regard to lead color. If It says "CW" rotation you're good. For convenience, call the Yellow lead L1, Green Lead L2 and Red Lead L3. Wire the associated power leads to the terminals designated L1, L2 and L3 on your equipment. You're good to go.

Q: I was just wondering why it will take so long to deliver. My friend purchased the same exact one from Amazon and it came in about 2 days

Supply chain delays, like everything else.

Q: i see the max voltage is listed for 600v will it survive 690 +/- 4% are the leads 1kv rated? i understand that it wont last as long on 690

I never used it on anything more than 480v. Couldn’t tell you if it would survive 690. As far as the leads being 1kv, it doesn’t say. Only states 600v rated.
