How is a run capacitor wired
Start Capacitor Vs. Run Capacitor Why You Can't Store A/C Power In A Capactor
hello YouTube this is Philip 20 again
today and what I've got for you is a
simple test I have a 80 to 100 8 micro
farad 330 volt 50 or 60 Hertz
capacitor okay and the rated temperature
for this is 65 degrees Celsius that's
pretty hot I don't know what it isn't
standard Fahrenheit but that's pretty
hard so I want to do some tests here is
our capacitor but if you can't see it it
says
88 to 108 now this device right here is
a device that I use for auditing my
house power consumption this is a bit
different than what you'll find as a
kilowatt meter so a kilowatt meter is
probably a lot better than this this is
a simple test for electricians that you
know heat pump technicians or
refrigeration technicians as well to
check the power consumption of a heater
for like a wall air conditioner or
heater you know making sure everything's
drawing the correct and on average now
this one has a specific location that
you can test there's x1 which means one
revolution of wire that is rotated
inside of this piece that would be
considered connecting the power
consumption just like that so if we do
that we'll have what you'll see is 0.5
amps okay
now you would say ok 0.5 amps s that's
nothing no big deal but then you come
over here
and do a quick test of the voltage okay
so you've got a voltage test for your
test leads right here once you got your
two voltage test leads in you flip it
over and then it shows 116 volts so if
we do point zero five times one one six
and that's five point eight watt power
consumption that uses more watt power
just plugging this in than it does to
run my kitchen lights my kitchen lights
use less power than that right there so
we know it's 101 to sixteen volts now I
tested it it right here with this one X
now we got a tenth as say X 10 X 1 X 10
let's see if we get a different reading
with it that right there so since it's
got 10 revolutions inside of there of
the power wire it's showing us zero
point seven one and that means it's zero
point seven one multiplied by 10 so this
number had been multiplied ten times so
instead of doing 0.7 0.7 3 amps its
point zero seven three you divide that
10 times okay and that's going to tell
you point seven three amps which we say
those five point eight watts with 116
volts
it's the point zero seven three
that's instead of five point four watts
it's eight point four watts and this
capacitor is starting to get hot I can
feel the temperature on I'll be right
back with a thermal imaging camera all
right this is the capacitor and look at
that that thing's getting really hot
was that 110 degrees almost 109 110 so
we know we're consuming power right just
by plugging this capacitor in 8.4 watt
power consumption now in perspective
this type of setup would not add
additional capacitance to my
refrigerator if I installed it and
there's a reason for that this capacitor
has a frequency that goes up and then
down and then up and then down because
that's why it's getting hot that's why
we're getting hot we're using the
capacitance continuously and that is
consuming the power to change the
frequency of the alternating current
which happens 60 times a second and that
means you're gonna be taking you know 60
times a second back and forth to 115 116
volts okay adding a capacitor to a
circuit like this is not only dangerous
because it gets hot and it could explode
depending on how you put it in if you
put it in a metal box and ground the box
it's probably fine but if you don't run
the box and this thing gets hot enough
it's gonna explode because it's under
continuous load and it never
shut down these capacitors are supposed
to be in line to a start circuit to a
motor and your standard box fans would
not benefit from this your DC motors now
they could benefit from direct current
because it doesn't change the frequency
up and down if 60 times a second it
stays the same polarity so the polarity
reverses an alternating current back and
forth 60 times a second whenever you set
it up and you run it the only thing
you're doing is powering the capacitor
back and forth it's discharging and
charging 60 times a second so remember
eight point four eight eight point four
six eight watts of power consumption out
of a 88 to 108 micro farad capacitor now
you got to remember the voltage is 330
voltage alternating current it will
charge fully to the 88 to 108 microfarad
at 330 volts alternating current
this is 110 volts alternating current
right here
so since I'm running less than a third
of the power that this capacitor runs at
oh well you know a little more than a
third I mean it's pretty close to a
third but we're only using one third of
the capacity because the capacitor will
not charge until it reaches the maximum
voltage that it damaging voltage which
is 330 volts on this one you would never
want to exceed 330 volts on this
capacitor because it's going to shoot
right through the there's a there's a
median inside the capacitor I can't
remember the name of it but it's gonna
damage it if you go past 3 her and 13 so
you're looking at a power consumption
device it's doing nothing but consuming
the power in my house it does not add
capacity because it's discharging and
charging 60 times a second and it's only
continuously making a load on the
inverter so is this something I would
put in my house no there's something
else that you could use it's called a
hard start capacitor if you're having
trouble starting your compressor there's
a device called a hard start I'll go get
one for a heat pump and show you this
this here is a super boost hard start
capacitor it's a sub co-brand which is a
very reliable brand for severe low
voltage or hard starting compressors so
if your system has a lower voltage than
what is mandatory to run an air
conditioning system you can use this to
start it because it might may not start
and what's nice about this capacitor it
is a 277 V AC so and it'll run one
through five horsepower motor okay
now this is designed for a heat pump
this is designed to plug into a 230
voltage alternating current circuit no
wiring changes are necessary to this
type of system if I was to connect my
system to this what I've got to do is
plug these two terminals in to the run
the Hermetic for the compressor and the
common so your Hermetic will go here in
common would go here the benefit of this
is it will start your compressor quickly
the drawbacks of this is it will kill
your compressor
quickly so I mean over a period of time
you're gonna lose your compressors
resistance inside of the start windings
which is going to kill it and nobody
wants their compressor go bad because
they're expensive to replace so if you
take in consideration of this what's
special about a hard start versus just a
capacitor this thing's getting nice and
hot now is the special thing about a
hard start is it has a relay inside of
here this box inside of this box there's
a relay this relay detects load from the
capacitance this load only turns on for
a very short period of time and then
turns back off when it's completed load
a load I'm talking about lock rotor amps
lock rotor amps is a certain amount of
amps that the system will draw during
startup you'll have running load amps
which is the amount of amps the system
should not exceed and then lock rotor
amps which is the amount of amps that
you should have during startup so let's
talk about running low dams running load
amps is something sample it's a
straightforward picture of how much
energy the compressor should not exceed
so if you ever go past that means either
you got a condenser coil that's very
dirty or you got it overcharged which
nobody wants an overcharge system so
let's say law programs here I put my
test lead on one of the wires right
there okay and then I tied this
capacitor into that capacitor right
there it will draw a good amount of
power it'll draw it quickly let's see if
we can test
so in all real-world aspects adding
capacitor to 115 volt circuit is not a
good idea the reason is because you're
consuming energy and just for even a
very short period of time you're
creating a lot of heat and just a second
I'll show you again the thermals
I mean who needs heat in her house first
you got to remove it and then you know
it's not beneficial if you have a hard
time starting a compressor use a hard
start these are designed to start
compressors if you need help with
finding a hard start give me a call I'll
show you what to look for for your
application thank you again
this is filled 20 with guns games and
racing and our hard to start y'all later
