What position in the circuit is a fuse placed to protect a transformer?
In series to every phase winding of transformer.
What size fuse do you use on 800kva transformer?
For an 800 kVA transformer, the size of the fuse depends on the primary and secondary voltage levels. A common rule of thumb is to use a fuse rating of about 125% of the transformer's full-load current. For an 800 kVA transformer at a standard voltage of 480V, this typically results in a fuse size of around 1,200 to 1,500 Amps, but it's essential to consult the manufacturer's specifications and consider local regulations for precise sizing. Always ensure that the fuse is selected based on both the transformer and application requirements.
What is ELSP?
An ELSP is a current limiting fuse used in series with the primary fuse of a transformer.
Which fuse is used for 100kva transformer?
1o amper
What is the fuse rating for 5MVA transformer?
50 amp
What size fuse is usually on a 40 VA transformer?
The recommended fuse size for a 40 VA transformer typically ranges between 1 to 2 amps, depending on the transformer’s specifications and the circuit it’s protecting. It's essential to consult the manufacturer's guidelines for the specific transformer being used, as the fuse should be rated slightly higher than the transformer's full load current to prevent nuisance blowing while still offering protection against overloads. Always ensure the fuse is compatible with the application and safety standards.
Does the fuse on the primary side of a transformer protect the secondary side?
Yes, but it's usual to have fuses on both sides of the transformer.
Where is the built in thermal fuse located on a power supply transformer?
the INside
What can you do as preventative maintenance for a power pole transformer so that the mineral oil does not boil?
Lower the rating of the primary fuse feeding the transformer.
Replaced the thermostat and the furnace works but wont turn on?
Sounds like you might have a blown transformer, or a blown fuse on the transformer. Hope for the fuse. Its on the Furnace. Be sure your white wire is on the heat side of the thermostat, and the red wire is on the correct terminal also. The transformer can be checked with a voltmeter.
Why does the primary side of a step down transformer burn out and not the secondary of a 480V to 240V transformer?
Sounds like the wrong size fuse protection was used. The transformer should be protected to its kva capacity.
Is it necessary to connect a fuse at the secondary side of a current transformer?
Definitely NOT! An open circuit (across a melted fuse for example) on the secondary side of a current transformer is subject to a dangerously-high voltage, so a fuse must not be fitted. The secondary side of a CT must never be open circuited.
