It depends on the resistance level in that area if the soil have low resistance then they will use high impedance system and vice versa..so reason behind this have to reduce fault current.

Why emitter follower preferred to transforms as a impedance matching?
because it has high input impedance and low output impedance
Definition of low impedance medium impedance and high impedance?
For instance: A microphone rated at 150 ohms to 300 ohms is considered low impedance. About 600 to 2 000 ohms is medium impedance, and 10 000 ohms or more is high impedance.
Compared to bipolars FETs have-a high input impedance b low input impedance c same input impedance?
FET s have very high input impedance when compared with Bipolar transistors.
Is 5000 ohm is high impedance?
Relative to 500 ohms 5000 ohms is a high impedance. It is ten times higher.
Which is better high input impedance or low input impedance and why?
That depends on the output impedance. In electronic we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance. An input impedance is called also a load impedance or an external impedance. An output impedance is called also a source impedance or an internal impedance.
In a multistage amplifier input impedance is high and output impedance is low justify the statement?
no. input impedance is low & output impedance is high
Why emitter follower preferred to transforms as a impedance matching?
because it has high input impedance and low output impedance
What is difference between high impedance busbar protection scheme and low impedance busbar protection scheme?
high impedance circit provides a varistor unit which has stabilising resistor which ll protect the relay from being operating for maloperations like through fault, CT faults whereas this varistor unit is provided internally in an numerical relay where the CT of class 5P can be used.
What are the main differences between FETs and BJTs in terms of input impedance?
FET has very high input impedanceBJT has very low input impedance

When does ALE float to its high-impedance state?
These pins are not at their high-impedance stateduring a hold acknowledge.

Definition of low impedancemedium impedance and high impedance?
There is no precise definition, but for instance: A microphone rated at 150 ohms to 300 ohms is considered low impedance. About 600 to 2 000 ohms is medium impedance, and 10 000 ohms or more is high impedance.
What are the dc characteristics of an OP-AMP IC 741?
High gain high input impedance low output impedance

Do you have high impedance test light?
no
