Thank you for explanation!

All your videos are excellent. I pass them along to new hires for training (I work at a company in the renewables DC electrical balance-of-system space)

John

Gutor FSE, i am sending you my greatest respect Thx a lot for the efforts

seinor?

Great video, really explains the product well!

great job

18:12 the mechanical equivalent would be a stop check valve (normally closed solenoid/pneumatic control would be most similar to scr). Love ur videos btw, helps me learn and actually helped me during my interview for ups'. Used to work in a nuclear power plant

Very informative

Hi, for CB1 & 52C of a commercial UPS(9:37) , does it detect DC current or voltage propagating into the AC mains?

how do I make a printout of your slides? it is very informative. I am a UPS engineer. thanks,

great information. what is your e-mail for Mr. Craig Williams?

how can I test a ups system after design before construction

Thank you for sharing your experience. Great work.

Where are your products manufactured?

If thier is a problem to an any outlet from UPS ,how can I reset the UPS ?

So are the ground fault detectors typically wired to the load side of the DC breakers? If not then opening the breaker would disconnect the fault detection and there would beno balance anymore.

good work,thanks!

good work,thanks!

good work,thanks!

Nice video, can I get your email pls?

awesome training

thank you,sir,good work.

good work!

And we have no any relay or alaram fir DC grounding in substation

How we find out exect location in substation DC ground fault with using mullti meter....sir

very good!!!

Questions: 1. How the contractual requirements between Ametek and Saft work on the project/PO level? Is Ametek Vendor providing single solution? Or Is this a JV? 2. The new lithium batteries chemistry introduce a lot of technical requirements for the batteries and interactions during operation. It seems the model of how electronics - battery is should be working and interfacing is not established yet. How Ametek assures they have all the info from Saft to implement system properly?

Great explanation.😊 -

I want to correct a comment mentioned in this video. I state that nowhere in IEE450 does it mention using internal resistance as a maintenance tool. This is not true. Although it is not mentioned anywhere in the recommendations for maintenance of a vented lead acid battery it is mentioned in an annex at the end of the report. I apologize if I misled anyone.

Is the 135V that you always reference the float for a 120V single phase system?

Great explanation of the new display!

Send me ups pdf notes

Esta perfecto este curso estaría vien si nos pusieran subtitulos al español además otro más de rectificadores HF Felicidades casi eh visto todos los videos de ametek gracias por compartir sus conocimientos

Dear AMETEK, Do you have any kind of UPS suitable for connect variable frecuency inverters?

This channel is gold for a electrical/electronics student like me.

👌🏻👌🏻thank you

Are you still around? I started a project of an off grid power supply for my new C-PAP [sleep apnia] machine that requires pure sine wave, and a few lights , using a new pure sine wave, " APC Back-UPS Pro 1000 S BR1000MS", with larger battery for longer run time because I lose power here a lot. My older non- sine wave UPS worked for years with my old CPAP . But after hauling everything out to the shed. and try it out, I found out that this [used but new] " APC Back-UPS Pro 1000 S BR1000MS" , which is supposed to be so smart and has a nice battery monitoring and load display and calculates time load voltage and also protects from high low and surge voltagages, was a lie. its all fake. this has no clue what the battery is doing. it seems to just have some kind of timer. make you wait 16 hours to get 15 minutes of runtime no mater if your battery if full charged when you put it in or if ,like me, use a 100 amp hour battery . 16 hours, for 15 minutes. can you point me to a schematic or idea of how to disable this . none of it is really needed anyway because it is all done via Bluetooth .to my phone ,from the battery. just looking for the easy ,cheap way out.

amazing

When normal power is lost, but normal power is fed thru ATS and you get normal power back within a couple of cycles; what are the sequence of the UPS? my understanding is to batterie power and back to normal after normal is restore to UPS

in ferroresonant transformer type Inverter, IGBTs are switched are at constant frequency (50/60Hz). while in PWM type inverters, IGBTs are switched at varying frequency. kindly correct if i am wrong

amazing that how from very simple ideas, you easily explain complex topics. Thanks. Looking forward to more webinars

thanks sir, learnt alot

thanks sir, learnt alot (power electronics, control system all in one hour), certainly made my life easire :)

I have the the arrangement where two sources are connected on the same battery bank 12* 4 =48 volts. One is solar through a charge controller , the other source is a rectifier connected to the load as well which source would charge the batteries and drive the load ?

Great video, thank you so much, sir!

50:59 Would you please give me scheme diagram about ups

07:26 what function of external transformer in UPS? for motor load did we also need transformer?

cool

Good video
