AI Thread Summary
A remote substation is typically defined as a facility that is not directly adjacent to the fault location but is part of the interconnected power system. In fault analysis, the local substation is where the protective device is located, while the remote substation may provide data through telemetry. The identification of local versus remote substations can depend on the specific fault location and its impact on the system. Understanding the positive and zero sequence impedances is crucial for determining relay settings. Accurate fault analysis helps ensure effective protection and reliability in power systems.

what exactly is a remote substation?

--------------------------------------------------------------------------------

hi there

i am doing a fault analysis on a power system that consists of two substations interconnected by a line.

The purpose of this project is to determine the positive and zero sequence impedances of the line and the source for different types of faults. I am doing this so i can determine the correct settings for the relays by use of a specific software.

The fault is applied on the line interconnecting these substations. How do i identify the local and remote substations? Does it depend on the fault location?

please assist..

thanks

Local usually refers to the place where the protective device is. It may gather data from remote places by telemetry.
 

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
