Explaining phase monitor|phase failure relay|ELECTRECA

Phase Monitoring Relays. ... Prevents three-phase motors from continuing to run after losing a phase that could result in motor burnout.
Phase monitoring relays. phase monitoring relays protect loads from voltage fault conditions. The devices provide protection against phase loss, phase reversal, and phase unbalance due to blown fuses, broken wires or worn contacts.

I want to thank you sir the education given so far so good I have learned a lot just asking you sir to continue we really appreciate and enjoy the way you explain it's really nice and clear thank you very much

[@electreca1]

Thank you, I will

[@kibacademy9619]

Congratulation brother...ur channel is very educative I did electrical but we didn't do much of this practicals....👍👍👍👍

[@electreca1]

Thank you........and well come. fill free to ask quetion here, i will always do my best to answer.

Thanks for watching

[@rosekamotho3081]

Very educative videos electreca,I have learnt almost all controls from your videos,I would just like to learn more on how to do the pump panel on auto and hand.

[@electreca1]

I will do more video on that, Thanks for watching.

[@samuelagbai7392]

Good day engineer. Nice job. Pls I want to ask, is there a way we can use a single phase on this device?

Good job engineer

[@kayiwareagan9385]

This guy has taught me automation at best, that i come here watch a video, go do the circuit amd get paid. My question is on this video. In the components the last component on your right, what exactly is that.

[@electreca1]

That's a borehole control panel, the device on the right is called floatless level switch. It's a protective device it switches off the pump incase water level goes below threshold.

Can I connect phase failure and breakers only exclude the other?

Great video

[@reyelectrical]

Now i understand thanks for this video man

[@lawrenceatkinson]

You didn't put it out there the way I would have wanted but I'd learn something about the device from you

[@mesumbeamstrong3122]

Engineer,is there a connection to bypass the phase failure,expecially when you are not in the disposition have another at that moment,and you want it to continue work before you go and look for another

[@georgeadeka7984]

Good work

Thank you so much 😀

Blessings, so elaborate.

[@chrismasika9786]

What of missing phase after the contactor i.e on the load side of a contactor assuming there was a fault with the contactor or overload relay for that matter will the phase failure still be of help?

[@moriamartinmariomuriira2644]

Hi, is it a must that the 3 phases entering the phase failure must go through a MCB each?

[@electreca1]

Yes, to to protect the phase failure.

[@felixnartey3759]

Should I please connect the phase failure before the contactor

[@electreca1]

Yes, The phase failure gets the current first before the contactor coil.

How can I sizing the contactor for each hp motor from 10hp to 50

[@sekyanzinathan7521]

Thanks u sir. Do u just need to keep on changing two phase of incoming power until you get right direction (when rectifying a change in phase at transformer)

[@electreca1]

You only interchange 2 phase once.

[@Kenyan_Electrician.]

Hey & should you interchange at the main breaker or at overload... please ?

[@chidiemelobe1044]

Nice video, but could you please teach with diagrams as well. Thanks

How to calculate voltage because some phase monitor start from 55 to 95 on under voltage

[@joshuawoolridge8378]

Great video, keep it up!

[@electreca1]

Thanks, will do!

[@demukaconceptelectric]

Good explanation.But I have a question? Does it mean that the phase failure relay is the one which is supposed to supply power to the coil of the contractor...

[@electreca1]

No... The phase failure should supply the circuit. let me explain in an example, you have a 3phase pump to run using a self-holding circuit. From control Breaker through phase failure(NO) through overload relay(NC(9798),) From here you can supply the circuit. Op it helps

[@smalls2845]

my question is, how do you select or calculate the rating of the phase monitor required for you circuit?

[@electreca1]

Normally the control circuit will draw a small current, the control component like Relay,timer,phase failure they have contacts that take up to 10Amps, those components rating is standard. It's only contactors that need sizing because they take different power sizes.

[@leonardochieng7220]

Hello can you pls explain how RM35TF30 voltage regulator work

[@drameriemmanuel1187]

How important is phase failure in single phase automatic changeover switch

[@electreca1]

Do you know that undervoltage/overvoltage might ruin most of the electrical devices in your installation if they have no internal protection? take an example, High voltage During a blackout, power might resume in high quantities like 300,500,1kv or more what will happen to your 220 or 240 device Under voltage you may experience consistent low voltage of below 100v, vulnerable devices will burn conclusion Phase failure is a must-have or at least something like AVS, or fridge gard for fridges Thanks for watching.

[@drameriemmanuel1187]

@electreca1 woow great .thanks so much

[@philipamosu4970]

Can it work if I supply 3phase voltage monitor relay with single

[@electreca1]

Yes, it can work for both single and three phase.

[@kariukikariri5759]

Hi you didn't explain on how to configure the timer over and under voltage plz

[@flashvideos5602]

If it latched to phase sequence failure how to reset it?

[@comedystorekissey2850]

Thanks brother but it's should be better if u use appropriate phase colours for easy understanding and even the beginners to avoid making mistakes.

Hi bro this video is great but I have problem in my blue phase coz the blue phase always burns out what's reason for that can I have answer please. Coz in our whole estate the blue phase burns so I'm finding a answer to solve this issue.

[@electreca1]

There may be 2 reasons 1)Overload Try to check the load(current at full load) If the Blue phase is current the highest current consider balancing. If balancing is not possible then consider changing the load cable to size that capable to support the demand. 2) Loose connection Be sure that connection that phase is tight and sound, any current carrying conductor carrying any amount of current if not tighter you have your cable burn. Check those two it will help.
