"Megger" high-voltage insulation tester

[@LithicStudios]

As an apprentice currently my first period of schooling, I appreciated this information greatly - thank you.

Many thank's for the video! Great information for myself. Being a Compressor Service Engineer! Great to know what you've said about the Inverter Drive issue!

[@lupo0144]

Thank you very much for this video! It's excellent! I'm a Compressor service engineer with a small amount of electrical knowledge! This is excellent for me!

[@watsonm67]

Thank you I was wondering if applying voltage to a vfd without taking the motor leads off would cause something like that. Thanks for not making me look like an ass by doing that!! Glad I checked out this vid👍🏻

[@0green1]

easy to follow. Well presented. And most importantly, correct.

[@omarimtiaz2372]

Thank you. Very precise and to the point

[@Johnomosquito10]

Very well said - great video. I think maybe the electricians meant to disconnect the VFD T1/2/3 load cables before testing the motor (we can hope)

[@1200bruiser]

Amen!

[@Froggability]

My finding is you almost always can megger electronic devices as long as active and main neutral are both disconnected. Only RF and surge protection devices that interfere with this and cause a fail

You mentioned a model with a hand crank. I have one in front of me right now, it also has 3 alligator clamps and a test button...... good times!

How much voltage should you send down to check the motor windings ?

[@jasonpierce1118]

Awesome video, thanks for great explanation!! More vids please

[@fardanfardann2322]

Thx you very much, specially your note regarding Meggering VFDs, I am about to approve the design from supplier to build the MCC panel with 6 VFD's, and Meggering after installation at the site, but I couldn't understand why it would damage VFD's and they are already designated to curry up to 400 Volts? can you please clarify it?

[@sunilsahoo3948]

in case of earth fault in any circuit the megger will indicate? ------- --

[@mgun1510]

This is a low voltage tester. High voltage is greater than 1000 volts.

[@kd5yut]

Built one for checking HV caps. works great

[@gopalmondal6319]

How Much

[@imtherealshady18]

hey could you do a break down of how to read the scale on the 500v setting?

[@MegaDee911]

Very good, your a natural, I agree with the comment for thr VFD.

[@bwasang]

how many seconds should you press the test button?

Thank you

[@MrKhalio]

thanks alot . good explanation

[@yougiovesjotube]

very good explication!

[@soda19811]

Please note 250/500/1000 volts is not HIGH VOLTAGE. High voltage is classed as anything above 1000v AC or 1500v DC. 250/500/1000 IS LOW VOLTAGE.

thanks, great job,

[@martinrivest5351]

Nice video

[@Guntrician]

Very good.

[@iserenadeyourmum]

very good now tell us how to test a switch board pls

[@seandempsey9396]

If you're woureid about damageing sencitive equipment then test at 250 v

[@aaravpatel12345]
