Why does a transformer blow the circuit breaker on the primary side if it is not connected to a load on the secondary side?
A normal transformer should not blow the primary side breaker when it is not connected to a load on the secondary. If it does, something is wrong. Check for shorted or burned windings. Make sure that it is indeed disconnected from the load - it might still be connected to something that is also presenting a fault.
What is the difference between thyristor fuse and normal fuse?
A: THYRISTOR can be used to clamp damaging energy as opposed to a fuse that must blow open and invariably takes time to blow. A thyristor is much faster and controllable actually if the problem disappear it can be made to open up again and restore power for normal operation.
What do you mean by package substation?
Prefabricated power distribution substation Its basically a whole 11kv substation but in one unit. It contains a transformer, ring main unit, fuse board and circuit breakers etc. It still uses as much space as a normal substation that houses a separate transformer, ring main unit etc but is easier to transport and is probably cheaper.
Why rated voltage is to be applied to primary for open circuit test?
Open circuit test on a transformer is usually performed to measure the IRON losses.Iron losses are produced due to eddy current and hysteresis losses. In open circuit test, the LV side, generaly the secondary winding, is kept open and the HV side, generaly the primary winding is fed with the rated voltage and frequency. The rated voltage is applied in order to setup normal flux in the transformer, which in return further produces the normal iron losses at rated voltage. the wattmeter connected at the primary side will show the power consumed due to iron losses. this calculation further utilized for determing the efficiency of transformer.
What is Difference between fade rate and fade depth?
Fade rate is the time to fade a certain amount. For example, Multipath fading on a microwave link may occur at 100dB/sec. Fade depth is the reduction from the normal received level, measured in dB.
What is the difference between planar transformer and AA normal transformer?
I am currently designing a planar transformer for a switch-mode power supply. From what I understand, planar transformer is better than a normal transformer due to its shape. It utilises flat E ferrite cores and winding tracks which saves space and is more compact for a power supply. It also has lower leakage inductance which makes it more efficient.
What is the difference between a micro pet and a normal pet?
the difference between a micro pet and a normal pet is that a micro pet is a really small animal such as a micro pig and a normal animal is a animal just like a normal person normal size normal wight and that is the difference between a normal animal and a micro animal.
What is the difference between normal saline solution and ringer's lactate solution?
What is the difference between normal saline solution and ringer's lactate solution?
What is the difference between a normal and a participating preference share?

What is the difference between normal and average respiratory rate?
The difference between normal and average respiratory rate is simple. Normal is healthy and cannot change and average most certainly can change.
What the difference between a pie and tartlet?
The treatment effect is the difference between the observed outcome and the "normal" outcome
What is the difference between sowing and planting?
The treatment effect is the difference between the observed outcome and the "normal" outcome
What is the difference between a normal guitar and a junior guitar?
The difference between a normal guitar and a junior guitar is primarily its size. A Junior guitar is shorter and about three quarters the size of a normal guitar.

What is the difference between currency paper and a normal paper?
the main difference between currency paper and normal paper is that the currency paper is made up of cotton fibres and the normal paper is obtainde from trees
