in isolation transformer earthing is not provide on secondary side but in ordinary transformer neutral of secondary side is earthed
AnswerAn isolation transformer is a 1:1 ratio transformer; its function is to electrically isolate the secondary side from the primary side without changing the voltage. An example of an isolation transformer is the one used in a shaver socket.
A distribution transformer is a step-down transformer, used within the electricity network's distribution system. An example of distribution transformer is a pole-mounted transformer, supplying low voltage to residences.
(Of course, all mutual Transformers provide electrical isolation between primary and secondary.)

Difference between isolation transformer and Scott-T transformer?
The Scott-T transformer was used to run 2-phase equipment from a 3-phase source. Older power distribution systems (and equipment) were 2-phase. An isolation transformer usually has the same input and output voltages (120:120, 240:240, etc) and is used to isolate the source from the load. Isolation transformers are used in medical equipment, for instance, to prevent a patient hooked up to a monitor from being electrocuted during an electrical fault.
What is the difference between primary electrical distribution and secondary distribution?
Primary electrical distribution carries medium voltage power to distribution transformers near the customers. Secondary electrical distribution transfers the power from the transformer to the households.
What is difference between isolation transformer and earth protection relay?
An isolation transformer is a mutual transformer having a voltage ratio of 1:1, so that the secondary circuit is electrically isolated from the primary circuit, yet subject to the same voltage.An earth protection relay is a category of protective relay that responds to an earth fault monitored by a current transformer (CT). In the event of an earth fault being detected by the CT, the relay with activate the trip circuit to a circuit breaker which will then disconnect the fault.
What is difference between interposing voltage transformer and potential transformer?
potential transformer is to maser and protection purpose the ivt is used for synchronicing purpose
What is the difference between power transformer and instrument transformer?
A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
What is the difference between isolation transformer and ferromagnetic transformer?
An isolation transformer is usually a ferromagnetic transformer. The question needs to be framed more usefully.

Is there a basic difference between a three phase power transformer and a three phase distribution transformer?
The basic difference is the secondary voltages. On a distribution transformer the secondary voltage is very high. This is to overcome line loss for transmission of electricity over long distances. A three phase power transformer is used at the consumers three phase services end to manipulate voltages that consumers need to operate their equipment. The transformer that feeds your house is considered to be a single phase power transformer.
what is ultra isolation transformer?
We are leading manufacturer of Ultra Isolation transformers in India . Ultra isolation is used to protect against electric shock to suppress electrical noise, insensitivity with special insulation between primary and secondary, and is specified to withstand a high voltage between windings. We have complete range of Ultra isolation Transformer in our Company .
Why you not use auto transformer for distribution purpose?
because autotransformer used for both purpose step up and step down but dustrubution need step down in case of this autotransformer not used for dustrubtion purpouseAnswerBecause an autotransformer (not 'auto transformer') does not provide electrical isolation between the secondary and primary.
Difference between step up and step down transformers?
Actually an isolation transformer may be physically the same as a Step up/Step Down transformer. The main difference is in the way they are used. Another difference is that in a normal transformer there will be capacitance between the 2 windings, between the windings and core, between the core and shell, etc. These capacitances bring in high frequency noise from outside, which will be transmitted in the secondary circuit. So [in an isolation transformer] wires are connected between each component, (not direct contact, but with insulation present). This permits a leakage current and eliminates unnecessary capacitance. I could make a start to answer this question. Isolation transformer: is a transformer with two separate windings, the primary and the secondary. There is an electrical isolation between the primary and the secondary. Nearly any type of transformer with two non-connected windings could be considered an "isolation" transformer, in that it electrically isolates the primary voltage from the secondary voltage. There are also transformers with one winding (called auto-transformers) and connections for input and output. If the input is low voltage and the output a higher, then you can say it is a STEP-UP transformer. If the input is high and the output is low, then you can say it is a STEP-DOWN. This type of transformer can not by used where safety is a large factor.
What is the difference between a balanced transformer and an unbalanced transformer?
there is nothing like a balanced and unbalanced transformer.
What is the difference between an ordinary transformer and resonant coupling energy transfer?
What is the difference between an ordinary transformer and resonant coupling energy transfer?
What difference's between potential transformer and voltage transformer?
Both are same. This is an instrument transformer used for metering & protections.
What is the difference between a 1.5KVA and a 3KVA transformer?
The 3 kVA transformer will weigh double the 1.5 kVA transformer.
