DESIGN
• All-film winding in insulated aluminum casing with
non-magnetic lid;
• IP00, indoor;
• Operating temperature - 10°C/+ 65°C (= maximum
temperature at surface of casing);
• Porcelain terminals with bolts M10;
• The maximum permissible values UN max., PV max.,
and Imax. must be observed.

Formula for calculating Pv(W) and I(A) :
Q = 2 π x f x U2 x C x 10–9 (kVAr)
I = Q/U (A)
Pv = I 2 x RS + Q x 10- 4 (W)
EXAMPLE
Type Phao 1.5/1µF(= version A) on U = 1000V and
f = 4000Hz ?
Q = 2 π x 4000 x 10002 x 10- 6 (Var) = 25130 Var
I = 25130/1000 = 25.13A
PV = 25.132 x 1 x 10- 3 + 25130 x 10- 4 = 3.145W
= > version A not suitable, take version B type Phao 2.2/1µF.
