Пример определения Uf:

Example of calculation of Uf:

1) Дано:

f =20 кГц, Uном=63 В, Cном=1 мкФ

Находим:

Uf =8,0% от 63 В=5,0 В

2) Дано:

f =20 кГц, Uном=400 В, Cном=0,015 мкФ

Находим:

Uf =9,0% от 400 В = 36 В

3) Дано:

f =10 кГц, Ut=Uном=100 В, Cном=0,01 мкФ

Находим:

Uf =58% от 100 В = 58 В

1) Given:

f =20 kHz , Ur=63 V, Cr=1 µF

Finding:

Uf =8,0% of 63 V=5,0 V

2) Given:

f =20 kHz , Ur=400 V, Cr=0,015 µF

Finding:

Uf =9,0% of 400 V = 36 V

3) Given:

f =10 kHz , Ut=Ur=100 V, Cr=0,01 µF

Finding:

Uf =58% of 100 V = 58 V
