5 tranformer izing n Which tranformer for which circuit? Each circuit need a pecific tranformer output: tranformer izing ut, to ize an equipment tranformer it i not enough to add up the power of the operating circuit, the permiible intantaneou power mut be conidered (inruh power) n How to calculate a tranformer power and ize? or equipment including automatic device, tranformer power depend on: The max. power needed at a given moment (inruh power) ontant power aborbed by the circuit Voltage drop Power factor 1) Determining the inruh power To determine the inruh power, we make the following aumption: Two inruhe cannot occur at the ame time Power factor co ø 0.5 at cloing Max. 80 % of device power upplied at the ame time Empirically and to implify, thi power can be calculated uing the following formula: P inruh = 0.8 ( Pm + Pv + Pa) Pm: um of all contactor holding power Pv: um of all indicator light power Pa: inruh power of the larget contactor Example : machine tool control cabinet contain : 10 contactor for 4-kW motor, holding power 8 V 4 contactor for 18.5-kW motor, holding power 20 V 1 contactor for 45-kW motor, holding power 20 V, inruh power 250 V co ø remote control relay, holding power 4 V 45 ignalling light, conumption 1 V Pm = 10 x 8 V = 80 V 4 x 20 V = 80 V 1 x 20 V = 20 V 25 x 4 V = 100 V 280 V Pv = 45 x 1 V = 45 V Pa = 250 V P inruh = 0.8 ( ) = 460 V at co ø 0.5 2) Determining the tranformer ize Epecially for control tranformer, jut read the ize below from the inruh power at co ø 0.5: Nominal Permiible intantaneou power V IE/EN power with co ø of : V IE and S Voltage drop izing curve at co ø 0.5 Inruh power in V Secondary 10 U nominal - 10% U nominal - 5% voltage in volt U nominal or power of 460 V co ø 0.5, the curve at U nominal - 5 %* indicate a value of 160 V * Value deliberately elected a a precaution 3) hecking the choice Make a check according to each piece of equipment : calculate the total um of the holding power of the winding and of the live indicator light then apply a factor: either that of 80 % of device held live at the ame time, or that from the actual calculation for your equipment The izing power mut be equal to or more than the reult of thi calculation Rule for determining the econdary protection rating : To check that the device choen i uitable, an approximate minimum hort-circuit value at the furthet point of the intallation can be obtained uing the following formula: I c/c mini = I c/c min. g fue : In 4 U U 2 x U c/c % + 2ρl ( P 100 ) S U = tranformer econdary voltage P = tranformer power U c/c % = tranformer hort-circuit voltage I = line length in m S = line cro-ection in mm 2 ρ copper = Ω mm 2 /m hooe the protection rating o a to obtain a cut-off time of 5" max. for the current I c/c defined above : I c/c min. type M: In 8 Example : control tranformer 630 V - 230/24 V at.no x m Inruh power of 460 V at co ø 0.5 entail minimum ize of 250 V Tranformer protection 25 g Line protection Operation I c/c min. = 24 = x x x 15 + ( ) = _ g 10 max = 5.22 _ DX 5 max..curve 8 321

6 protection of tranformer and their line n Protection of line eneral Line mut be protected againt overload and hort-circuit. Protection againt overload i only compulory if the line i likely to be affected by an overload current. Thi protection can be intalled at the head or end of the line. Protection againt hort-circuit i compulory in all intallation ; thi protection ha to be intalled at the head of the line Supply line (tranformer primary) The tranformer i a devicethat cannot generate overload. It upply line require protection againt hort-circuit only. When a tranformer i energied. a very high inruh current i produced (in the region of 25 In) for approximately 10 m. The line protection mut take thee 2 factor into conideration. Legrand offer 3 poibilitie: am fue cartridge, type D M (average value of the magnetic 12 In, with a tandard adjutment range between 10 and 14 In), type M (average value of the magnetic 7 In, with a tandard adjutment range between 5 and 10 In) Minimal protection rating for primary upply line on tranformer (1) Power 40 V 63 V 100 V 160 V 220 V 250 V 310 V 400 V 450 V 630 V 800 V 1000 V 1250 V 1600 V 2000 V 2500 V 4 kv 5 kv 6.3 kv 8 kv 10 kv 12.5 kv 16 kv 20 kv 25 kv 31.5 kv 40 kv 50 kv 63 kv 80 kv 100 kv 125 kv 160 kv 200 kv 250 kv 230 V ingle - phae 400 V ingle - phae 230 V three - phae 400 V three - phae am M M type M am M M am M M am M M artridge curve D curve with inruh artridge curve D curve artridge curve D curve artridge curve D curve or M or M current limiter or M or M or M or M or M or M (2) 160 (2) (2) 160 (2) (2) 200 (2) Operating line (tranformer econdary) Thi line mut be protected againt overload (enure that the protection rating choen i tranformer econdary current) and hort-circuit (enure that a hort-circuit occurring at the furthet point of the line will trigger the protective device within 5 econd. Legrand offer two poibilitie: g cartridge fue, type M (magnetic et to 7 In average). If the tranformer only upplie a ingle operating line, and provided the calculation how perfect compatibility, tranformer protection (if on the econdary) and line protection can be one and the ame ingle protective device perform both function (ee table of tranformer protective device). If the tranformer upplie everal operating line, overload and hort-circuit calculation mut be performed for each individual line (1) Thee value are given for information only for tranformer with inruh current of around 25 In.
