As part of my dedication to help aspiring Filipino Electrical Engineers broaden their knowledge on the profession they have chosen and to enable them to compete in the world job market particularly at these economic downturn, I will be presenting some tutorials on Electrical Engineering standards, practice and calculations.

I have already written several tutorials in The Filipino Engineer. Incoming tutorials will be

- MVA Method
- Short Circuit Study
- Short Circuit Calculations
- Load Flow Calculations
- Motor Starting Calculations
- Unbalance Fault Calculations

- Arc Flash Hazards
- TBA

I have seen how excel 2003 is used for co-ordination study so far as relay is concerned. But how fuse characteristics is plotted in excel 2003

Unlike protective relays which got a T-C curve based on standard formula, IMHO fuses don’t have. To plot fuse TC curve, it must be based on manufacturer’s data. S&C provides TC curves for their fuses. You can download them here.
