I have never come across this terminology in the electrical trade. The letter L is a symbol used to express inductance. The unit of measure is a "Henry"In some documentation the system voltage legs are referred to a A, B, and C.

In the electrical trade the letter L is used with a reference number behind it.

For example L1, L2 and L3 represent the three legs of a three phase system. Incorporating the letter N into the system would give you a representation of a three phase four wire system where you would obtain a voltage from each leg to the grounded neutral. The voltage from any of the three legs to neutral would be, leg to leg voltage divided by 1.73. This would give you the leg to neutral voltage. For example 480 volts / 1.73 = 277 volts or 600 volts /1.73 = 347 volts.

Sounds like a 240v motor. LA would be live connection 1 (120v); LB would be live connection 2 (120V) and N is the neutral connection.

What is thermal voltage?

In semiconductors, the relationship between the flow of electrical current and electrostatic potential across a p-n junction depends on a characteristic voltage called the thermal voltage, denoted VT.


What does L1 L2 and N mean in electrical terms?

L1 and L2 stand for "Line 1 and Line 2". These are the two incoming hot legs of a single phase, 220V electrical supply as is typical for residences. The N stands for the neutral or grounded conductor. This is the white wire in a residential system. Since L in electricity stands for inductance, L1 and L2 could also possibly be inductor 1 and inductor 2. And the N in electricity means Number of Turns (of the copper wire into a coil). Therefore, it could be about residential wiring or inductors.

What is DYN11 of a transformer?

It's a description of the some of the electrical properties of the transformer. This is a Delta connected highside (the D), wye connected lowside (Y) that is grounded (N) and there is a 330 degree phase shift between the highside and the lowside (the low voltage is leading the high voltage by 30 degrees).


What is the application of z parameter?

Impedance parameters or Z-parameters are properties used in electrical engineering, electronics engineering, and communication systems engineering to describe the electrical behavior of linear electrical networks when undergoing various steady state stimuli by small signals. They are members of a family of similar parameters used in electronics engineering, other examples being: S-parameters,[1] Y-parameters,[2] H-parameters, T-parameters or ABCD-parameters.[3][4]The Z-parameter matrix for the two-port network is probably the most common. In this case the relationship between the input currents, output voltages and the Z-parameter matrix is given by: .whereFor the general case of an n-port network, it can be stated that
