How many volts is the secondary voltage busbar of a 35kV system
It steps down the line voltage to a safe, standardized level (usually 100V or 110V) for the secondary circuit. While both voltage classes fall under the medium-voltage category, the engineering requirements for 10kV (12kV-rated) and 35kV (40. 5kV-rated) equipment differ significantly in insulation levels and physical dimensions. Primary distribution lines carry this medium voltage power to distribution transformers located near the customer's. This scheme is common at 230 kV and below and in older stations; sectionalizing the main bus can limit the impact area. Main and transfer suits sites where breaker maintenance flexibility is required, budgets are constrained, but a bus fault–tolerant arrangement (like ring or breaker‑and‑a‑half) is. The standard aims to consolidate AC and traction voltages within the industry and defines the following bands: Bracketed are non preferred and should not be used if possible It is recommended that only one series be used. Usually they use 110 kV or 220 kV voltage level. Voltage/BIL: 35 kV class, typical BIL 170 kV. Short-circuit: 25–40 kA short-time withstand common; confirm with system fault.
