## Question 1: Three-Phase Fault Analysis
A three-phase fault occurs at a bus with the following system data:
- System voltage: 138 kV
- Generator reactance: j0.15 pu
- Transformer reactance: j0.10 pu
- Line reactance: j0.08 pu
**Calculate the fault current in amperes.**
**Options:**
A) 12,500 A
B) 15,240 A
C) 18,960 A
D) 21,340 A
**Solution:**
Total reactance = 0.15 + 0.10 + 0.08 = 0.33 pu
Base current = 100 MVA / (√3 × 138 kV) = 418.4 A
Fault current = 418.4 / 0.33 = 12,677 A ≈ **12,500 A (Answer: A)**
---
## Question 2: Symmetrical Components
For an unbalanced system with line currents:
- Ia = 100∠0° A
- Ib = 80∠-130° A
- Ic = 60∠110° A
**Calculate the positive sequence current I₁.**
**Solution:**
I₁ = (1/3)[Ia + a×Ib + a²×Ic]
Where a = 1∠120°

Primary current through Relay A = 6000 A
Secondary current = 6000 × (5/800) = 37.5 A
Using standard inverse curve equation...

## Question 2: Distance Relay Zones
A 100-mile transmission line has the following protection zones:
- Zone 1: 80% of line
- Zone 2: 120% of line + 50% of next line
- Zone 3: 200% of line
**Calculate the reach settings for each zone if line impedance is 0.8 Ω/mile.**

# IEEE C37.2 - Device Function Numbers (Demo Mode)
## Purpose
IEEE C37.2 defines standard device function numbers and contact designations for power system devices. This standard provides a universal numbering system for protective and control devices.
## Key Device Numbers
### Protection Devices
- **21** - Distance Relay
- **50** - Instantaneous Overcurrent
- **51** - Time Overcurrent
- **67** - Directional Overcurrent
- **87** - Differential Relay
### Control & Monitoring
- **25** - Synchronizing Check
- **27** - Undervoltage Relay
- **59** - Overvoltage Relay
- **81** - Frequency Relay
### Circuit Breakers & Switches
- **52** - AC Circuit Breaker
- **89** - Line Switch
- **94** - Tripping Relay
## Practical Applications
- Standardized protection schemes
- Universal documentation
- Simplified maintenance
- International compatibility
