Transformer & HV Switchgear - Training Guide
============================================================

MINIMUM RESOLUTION: 980 x 600 px
RECOMMENDED: 1920 x 1080 (16:9) or larger

SIMULATOR OVERVIEW
----------------------------------------
HV transformer and switchgear simulator covering protection relays, tap-changer operation, oil temperature monitoring, and circuit-breaker sequencing per IEC 60076 and IEEE C57.

Standards: IEC 60076 · IEEE C57 · IEC 62271

INTERFACE LAYOUT
----------------------------------------
- LEFT PANEL: System controls (Start/Stop/ESD/Reset, Mode toggle)
- CENTER: P&ID schematic with real-time process visualization
- RIGHT PANEL: System gauges, operational checklist, alarm list

OPERATING PROCEDURES
----------------------------------------
  Step 1: Verify transformer oil level and temperature
  Step 2: Check protection relay settings
  Step 3: Close earth switch (verify open position)
  Step 4: Close HV circuit breaker
  Step 5: Verify secondary voltage
  Step 6: Set tap changer to auto
  Step 7: Monitor load current and temperature
  Step 8: Record DGA readings

SCENARIOS
----------------------------------------

  Transformer Energization:
  Pre-checks, close HV breaker, energize transformer, and verify secondary voltage.

  Buchholz Relay Trip:
  Respond to Buchholz relay alarm — gas analysis and decision to re-energize.

  Tap Changer Operation:
  Regulate secondary voltage using OLTC during load variations.

ALARM RESPONSE
----------------------------------------
  BUCHHOLZ_TRIP [ALARM]: Buchholz relay trip — gas detected
  WINDING_TEMP_HIGH [ALARM]: Winding temperature critical
  OIL_TEMP_HIGH [WARNING]: Top oil temperature exceeds alarm
  OVERCURRENT [ALARM]: Overcurrent protection operated
  DGA_ALARM [WARNING]: Dissolved gas analysis abnormal
