# Three-Phase DCRM Flask API - Quick Start Guide

## 🚀 Quick Start (3 Steps)

### Step 1: Start the Flask API
```bash
python dcrm_flask_api.py
```

**Expected output:**
```
 * Running on http://0.0.0.0:5000
 * Restarting with stat
 * Debugger is active!
```

### Step 2: Open the Test Frontend
Double-click: `test_three_phase_frontend.html`

OR open in browser: `file:///c:/codes/dcrm/pranit/csv_kpi/combined/test_three_phase_frontend.html`

### Step 3: Upload and Test
1. Enter Breaker ID (default: `6926e63d4614721a79b7b24e`)
2. Enter Operator Name (default: `Test Engineer`)
3. Upload 3 CSV files:
   - 🔴 Red Phase (R): `df3_final (1).csv`
   - 🟡 Yellow Phase (Y): `df3_final (1).csv`
   - 🔵 Blue Phase (B): `df3_final (1).csv`
4. Click "Upload & Analyze All Phases"
5. Wait 90-180 seconds for processing
6. View results!
