C: Segmentation fault when using free() - Please Help! This is giving me a big headache. Using free() for some reason results in segmentation faults. I'm working on making linked structures to represent polynomials modulo a prime p. For the insertion sort below: the consumed pointer (the one...

AVR fault possible?? Can you help? Hi there and hello to ALL, First post and greatfull for any help. I've got an alternator suffreing voltage problems. To start with the voltage droped off to 360v when carring a small load of 17kw. New avr fitted and now running at 400v correctly. The...

Hi, I'm trying to perform a short circuit fault calculation on this transformer and load I have when a 3 phase bolted short (worse case) occurs. The transformer specs are below: Z(transformer)=5%, Z(cable)= .00306 + j.0027, Delta/Star 6.6kV/400V I can understand calculating the short circuit...

Not a homework question, Just trying to get more information about it. Its hard to find a textbook or a site that explains this well. thanks

A 20 KV switchgear have equipped with one zig-zag earthing transformer. As you know, A grounding transformer must handle the unbalanced load on the circuit as well as the duty during line-to-ground faults. If the circuit has a lot of unbalance load, then we must concern the continuous rating of...

As you know, for Earth fault protection of electrical system, the residual current measurement is often performed using the three line CTs. But in this case the protective relay must be slightly time-delayed to avoid spurious trips caused by circulation of a false zero sequence current following...

My landlord came to pick the rent money this week end. I asked him for his account number so I could transfer him the money but he told me that he didn't have one (which was obviously a lie). I didn't think much of it and the next day I gave him the money in cash, with intentionally adding a $5...

Six, 6.6kV ,3phase, alternators are connected to a common set of bus bars. Each has positive negative and zero sequence reactances of 0.90 ohm, 0.72 ohm, 0.30 ohms respectively . An Earth fault occurs on one bus bar . Determine the value of fault current if all alternator neutrals are solidly...

In one of the industrial site, the no earthed system has been chosen in electrical designing stage. Therefore nobody anticipated a strong Earth fault current in the system. On the other hand, the primary earthing system was not installed very well and related standards recommendations weren't...

We are using 120V commercial grade electronic ballasts, properly grounded, rated at 2Amps to drive two low pressure UV lamps submerged in water rated at 800mA. System requirements are to use GFI barkers with each ballast. This installation in a wastewater treatment plant, where there are...

Why is Katrina damage Bush's fault? Well who else is there to blame but Bush and FEMA?

Will California eventually split away from mainland America? (along the San Andreas fault)

Yup, here's why. Kerry was informed of security lapses at Logan International Airport. Kerry immediately forwarded the information to the Bush administration, but he should have known that the Bush administration was incompetent and would not prevent an attack. Therefore it was Kerry's...

Segmentation Fault ! What does it mean? I often get that in GCC. How to overcome that ? please help!

i have a problem can somone help please, i have this message with a blue screen, STIMON caused a protection fault in module user.exe at 0003:00009e46 i have a printer and scanner connected anthon 1.8
