The isolation transformer provides a electrical mean to separate the source and load. Also, The isolation transformer will protect against surges and spikes as the primary winding due to it's magnetic property will impose more resistance (reactance) to higher frequencies such as spikes and such.
where Xl is the impedance (resistance) of the primary winding. In this equation, one can see that higher frequencies increast the impedance of the coil proportionally to the rate of frequency.

What are the disadvantages and advantage of inertial Navigation System?
the disadvantages is it need to give data before flight
What is a base isolated building?
also known as seismic or base isolation system.
If the loads were only 240v on a single phase 240v system with a center tapped transformer the neutral conductor would carry?
If a load were only 240 volt on a single phase 240v system with a center tapped transformer the neutral conductor would carry no current.
What advantage does the country who does not use the metric system have?
The country that does not use the metric system has the advantage that its old equipment continues to work. Its old measuring system continues to work. It does not need to make changes to sell in its own markets.
What is advantage of closed blood circulatory system?
There isn't another way.
What is the difference between an isolation transformer and distribution transformer?
in isolation transformer earthing is not provide on secondary side but in ordinary transformer neutral of secondary side is earthedAnswerAn 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.)
What is the purpose of isolation transformer?
An isolation transformer (or more commonly, amplifier) reduces noise in the system from the power source. This is especially necessary in medical applications where the signals that are being read are very tiny and even a small amount of noise can disrupt a signal and make it unreadable.
Difference between and rcd and an isolating transformer?
An rcd is a device designed to limit duration of electrical shock by disconnecting the circuit when a fault is detected. An isolation transformer is a 1 to 1 (same voltage and current in and out) transformer that keeps one part of an electrical system physically unconnected to another part of the system. It does this by using the principle of a transformer to allow current flow, without actually connecting the load to the source wires.
What are the factors affect the magnitizing inrush current in power transformer?
1- residual flux existing before enegizing the transformer . 2- size of transformer . 3- size of power system. 4- type of magnetic material of the core. 5- the method of energizing the transformer.
What is base isolation?
also known as seismic or base isolation system.
What can be used to electrically isolate a piece of equipment from the power distribution system?
Assuming you are speaking of a standard 120v AC power, a simple one-to-one isolation transformer is made for this purpose. Be sure power rating is big enough for the load.
What are the disadvantages and advantage of inertial Navigation System?
the disadvantages is it need to give data before flight
What does E.W.I.S stand for?
electrical wiring isolation system
Advantage using system in life?
for safety to not break the speed limit and to have your seat belts buckled before setting off.
What are different types of transforms?
A small list of Transformers1. Distribution Transformers2. Padmount Transformers3. Station Transformers4. Station Transformers Various specific electrical application designs require a variety of transformer types. Although they all share the basic characteristic transformer principles, they are customize in construction or electrical properties for certain installation requirements or circuit conditions.Autotransformer: Transformer in which part of the winding is common to both primary and secondary circuits.Capacitor voltage transformer: Transformer in which capacitor divider is used to reduce high voltage before application to the primary winding.Distribution transformer, power transformer: International standards make a distinction in terms of distribution transformers being used to distribute energy from transmission lines and networks for local consumption and power transformers being used to transfer electric energy between the generator and distribution primary circuits.Phase angle regulating transformer: A specialized transformer used to control the flow of real power on three-phase electricity transmission networks.Scott-T transformer: Transformer used for phase transformation from three-phase to two-phase and vice versa.Polyphase transformer: Any transformer with more than one phase.Grounding transformer: Transformer used for grounding three-phase circuits to create a neutral in a three wire system, using a wye-delta transformer,[85][90] or more commonly, a zigzag grounding winding.Leakage transformer: Transformer that has loosely coupled windings.Resonant transformer: Transformer that uses resonance to generate a high secondary voltage.Audio transformer: Transformer used in audio equipment.Output transformer: Transformer used to match the output of a valve amplifier to its load.Instrument transformer: Potential or current transformer used to accurately and safely represent voltage, current or phase position of high voltage or high power circuits.Pulse transformer: Specialized small-signal transformer used to transmit digital signaling while providing electrical isolation.
