Floating Neutral Impacts in Power Distribution

Introduction If the Neutral Conductor is opened, broke or lost at either of its source side (Distribution Transformer, Generator or at Load side – Distribution Panel of Consumer), the distribution system’s neutral conductor will “float” or lose its reference ground Point. The floating neutral condition can cause voltages to float to a maximum of its Phase volts RMS relative to ground, subjecting to its unbalancing load Condition. Floating...

Vibration Damper in Transmission Line

Vibration Damper in Transmission Line: Wind-induced vibration of overhead conductors is common worldwide and can cause conductor fatigue Near a hardware attachment. As the need for transmission of communication signals increase, many Optical Ground Wires(OPWG) are replacing traditional ground wires. In the last twenty years All Aluminum Alloy Conductors (AAAC) have been a popular choice for overhead conductors due to advantages in both...

Explain thin film resistors and wire-wound resistors

Thin film resistors- It is constructed as a thin film of resistive material is deposited on an insulating substrate. Desired results are obtained by either trimming the layer thickness or by cutting helical grooves of suitable pitch along its length. During this process, the value of the resistance is monitored closely and cutting of grooves is stopped as soon as the desired value of resistance is obtained.b. Wire wound resistors – length of wire wound around an insulating cylindrical core are known as wire wound resistors. These wires are made...
