CPT Control Power Transformer

2003-09-09 - The Type CPT is an indoor, self-cooled, single-phase, dry-type, control power transformer designed to provide control power in medium voltage switchgear.

Nominal primary voltages range from 2.4 kV to 14.4 kV, 60 Hz. Secondary voltages are configured for series/parallel operation at 120 V or 240 V. Output kVA ratings of 5, 10, or 15 kVA are available.

Standard BIL ratings of 60 kV are available for 5 kV applications, and 95 kV BIL for 15 kV applications. The units are for use in an ambient temperature of 30°C for full kVA rating, or 55°C for 86% of full kVA rating. The winding temperature rise for 5 and 10 kVA units is 55°C, and for 15 kVA units is 75°C.
