# What Voltage Should I Test At?

## 2.5 kV vs 12 kV ? Do I need 12 kV? Is 2.5 kV enough?

The CAPO 2.5 (2.5kv test voltage) is adequate for most testing applications. Additionally, Power Factor (PF) results can be corrected to 10 kV for comparative purposes. For larger high-voltage apparatus's or when a minimum of 10kV is specifically requested by users, the CAPO 12 (12kV test voltage) is available from Raytech.
