6 FAQs about [Two-phase capacitor function classification standard]

What is the rated voltage of a capacitor?

Capacitors are applied the rated voltage at 50 Hz with 20 superimposed pulses of 2.5 kV for class X2 and 5 kV for class Y2. The rated voltage is maintained for 2 min. after the last discharge. This is a destructive test, and the failure condition is that cheesecloth around the capacitor shall not burn with a flame.

What are the IEC codes for a capacitor?

Commonly used as buffer, coupling, and bypass. Its IEC codes are X7R/2XI, Z5U/E26, Y5V/2F4, X7S/2C1, etc. Reading the explanation above will conclude that with the plasticity of ceramic materials, we can make different styles such as: High voltage power capacitor.

Is a capacitor bank a definite purpose?

The capacitor bank or cable shall be "isolated" as defined in IEEE C37 .04a-2003, 5.11. For circuit breakers identified as a Class C1 or C2 (formerly referred to as definite purpose), Tests to prove Class C2 have to be performed according to the requirements of Table 2 of IEEE C37.09a-2005.

What is a capacitor test?

This test is to ensure that capacitors do not ignite at a defined electrical overload. Capacitors are applied the rated voltage at 50 Hz with 20 superimposed pulses of 2.5 kV for class X2 and 5 kV for class Y2. The rated voltage is maintained for 2 min. after the last discharge.

What is a power film capacitor?
