Medium Voltage—Primary Reactor (10–13.8 kV)
Primary Reactor Starter (10,000–13,800 volts)
Starting sequence
1. Refer to the primary reactor starting sequence (“Starting sequence,” p. 35).
Standard features
• 4 kVA control-power transformer
• Primary and secondary current transformers (CTs)
• Potential transformers (PTs)
• Grounding provisions

Dimensions
Typical dimensions for remote-mounted primary reactor starters are shown in Figure 36, p. 47.
PFCCs, if required, are housed in a 36-inch wide auxiliary cabinet (not shown). Always consult the
submittal drawings for as-built dimensions.
