Standardize Symbols: Replace all circuit breaker representations with standard IEC rectangular CB symbols, and clearly distinguish off-load isolators and earth switches. Add Protection & Measurement Scheme: Insert CTs and VTs across the 6.3 kV generator tails, 33 kV transformer bays, and the outgoing 33 kV line for protection relays (ANSI 87G, 87T, 50/51, 27/59, 59N) and utility-grade Revenue Tariff Meters. Remove Redundant Devices: Eliminate one of the series isolators on the 33 kV outgoing line, and add an integral Earth Switch to the remaining line isolator. Incorporate Bus Sectionalizing: Introduce a Bus Tie / Sectionalizer breaker on the 6.3 kV or 33 kV busbar to allow independent operation of Gen 1 / T1 while servicing Gen 2 / T2. Add Surge Protection: Position 33 kV Lightning Arresters (LA) at the line terminal termination point and near the 33 kV transformer high-voltage bushings.
