- In this video, I will show you how to troubleshoot a low insulation on a switchboard (applicable only to low to medium voltage system).
A conductors insulation degrades the day it is made. That is why onboard, we do insulation resistance test.
Hello I am Mark Roy, I am an Filipino electrical engineer, signed on as an electrician on a ship, most of my ships I have I have been to were containerships, This time, I am on a bulk carrier ship.
I love taking pictures and videos, but not fond with speaking in front of a camera. That is why I made this video as a challenge for me. I want to progress myself in the upcoming more videos.
If I did not torture you with my robotic voice, then please consider subscribing. It will be a huge confident boost for me. Thanks! See you soon.

Your videos are a joy to watch and your troubleshooting methodology are explained very well. They're very useful to help teach our junior engineers the basics of troubleshooting on a ship.
Another legit marine maintenance technician. 👏🤝
Very useful ! We wait for more info !
Very clear explanation. thanks.
The best talaga basta pinoy ETO. More power to your channel sir.
Thank you for very detailed explanation sir. ❤️ Kuddos
Well done, it fact this is most headache job of ETO as its not an easy task not find and isolate the earth faults
Thanks sir nandito Lang pala hanap hanap ako SA TH-cam ..dito kulang makita salamat SA magandang tutorial at mahusay na pag gawa
Thks sir, so much help 👏
Thank you!
Bravo 👍
Very nice sir
Good information...
Ayos lods simple at klaro demonstration
Nice
Cool!
Useful video. well done
Thank you sir
Thank you sir, crane nmn sunod sir, common troubleshooting. Thanks safe voyage
Thanks, from electrical cadet on viking sea :D.
Galing nyo boss
Nice background music nd expln.
Good day Mark, Thanks for the video, it’s really entertaining…. But for a load like tv, you think is it possible to deteriorate the insulation of the wires? Thanks again
Love from India 🙌🏼
nice sir.
Thanks sir
Is it gonna be replaced while the ship at port, or for class repair ?
Hello! I am an engineer and the insulation problem is not clear to me. Your video is great and worth seeing! At the very beginning of the video (0:46), you measured current with the tester. Could you pls provide a drawing of this connection, pls? Also, your explanation of the motor is not clear to me as well. Why if T-face grounded it shows 0 Ohm insulation? I can understand that the current will flow with the easiest path from the R-face through the grounded U-winding to the ground (1:34). I was wondering if this current will back through the T-face ground and why? And why U-winding will be burned?
Hi Roy, Do you have a good understanding of the instrument type earth leakage monitors, how they actually work?
do you know how to apply for cruise line job i want join cruise line as an electrical job and one more question is if i am appply an an 4th engg so this p[ossible or not
Wow
What are the low insulation alarm limits for 220 and 440V panels according to Panama and Marshall flags.
❤
Can you explain how low insulation monitoring instrument working?? Based on DC Injection. Thanks.
Which editingg software do you use sir
Ehh like at share natin Yan Lect para marami tayo matotonan ..
Sir pa vlog nman po sa reverse power, salamat
Maganda Yan Kasi actual na trouble shooting Lect
Thanks for the bright info sir, tanong lang po sana ako ano po editor gamit nyo for making Schematic diagram, galing kasi!
Thanks sir. Lumafusion po gmit ko sa ipad. Mejo hassle ang procedure sir. Kaya nman yata sa ibang editor apps.
what dose mean TPYC-38 in plate name
Anong pwedeng paraan para maitago muna ang fault sakali darating n k u sa pwerto at meron psc na darating.
Sir Anong Tawag mo sa tatlong ilaw Sa switch board at Anong ibig sabihin nyan?
Sir.kung ok lng po sa inyo,pwede po ba malaman kung ano-anong reading nakuha nyo po sa linya?
Hello sir .parequest po sa insulation testing of ng machine .salamat po .
Meron ako video sana sir kaso nabura ko mga vids. Anyways.
The most ideal way to test insulation of a machine is when it is in running condition. Kasi andun yung mga factors like temperature, vibration, etc2. Pero hindi kaya i-insulation test mo ang machine while energized. The closest we can achieve this ideal way is to check before and after run for few minutes. Tapos before mag test dapat may good ground ka, hindi naka energized ang machine. For low to medium voltage machine, spot-type lang, mga 1minute lang na i insulation test. Sana nakatulong. Salamat.
common problem experienced in ship
simple wire marking would make the process much faster
Sir pwede rin naman na patayin mo isa isa yung breaker, tas pag nawala yung low insulation, yun na yung problema sir. Alam mo na. Pwede din naman yun di ba
Yun nga ginawa nya diba. Hinanap lang nya specifically kung saan ang problema. Mas mabuti nga nahanap nya kaysa i isolate lang ang breaker which karamihan ng elec ginagawa tamad na nahapin yung saan nag short.
What is the Meaning of low insulation?
Wirings and cables have the copper conductor core and insulation surrounding. as time goes by, this insulation material may deteriorate over time. and current will leak to the ground. the metal hull in this case.

Pwede ko po ba kayo add sa messenger? 1st time elect. Po ako sa bulk, and if I have questions maybe I can ask? Thanks for replying
Low insulation will cause a bigger problem its just a matter of time
EE ka po ba sir?
Yes sir. Registered electrical engineer po ako. Pasensya ka na kung matagal reply ko. Sa port lang kasi ako nagkaka internet. Thanks
Thanks sa info lecky, just keep safe lang po and God bless
OLD SCHOOL WOULD USE A MEGGER !!!!!!!!!!!!!!!!
What would New school use instead ?.
@@rscelectrical7091 :
electrical hipot test !!!!!!!!!!!!!!!
Pano mg.trace pag live sir?
