GE Consumer & Industrial Power Protection Procera Plus Design, Drawing and calculation software for industrial low voltage installations including distribution circuits
ProceraPlus The new HD384 and R064-03 standards require that the design of a low voltage distribution system includes the determination of all perspective short-circuit and fault current levels. 2 GE Consumer & Industrial Industrial Components Team
ProceraPlus ProceraPlus is a software to design & calculate • Cross section of conductors • Fault levels • Switchgear selection • Draw single line diagram 3 GE Consumer & Industrial Industrial Components Team
ProceraPlus From transformer to end-user circuits In Procera Plus a project is entered starting at the Upstream device (source supply ) moving to Downstream (end-user circuits) This method is used to determine the protective devices and cable cross-sections First the source must be defined, then the distribution circuits and finish by end-user's circuits. In Procera Plus, any circuit, distribution board or end-user circuit can be changed at any time. 4 GE Consumer & Industrial Industrial Components Team

ProceraPlus Project Started – Type of Source There are three possible choices : • Transformer HV-LV • Genset • Direct supply from utility board (LV direct 11 GE Consumer & Industrial Industrial Components Team
ProceraPlus Project Started – Source Characteristics Transformer They can be entered: a) from a file giving sources impedances and standard Powers or, b) from Ukr, short circuit voltage in % for transformers, equivalent to impedance 12 GE Consumer & Industrial Industrial Components Team
ProceraPlus Project Started – Source Characteristics Genset: They can be entered : a) from a file giving sources impedances and standard powers or, b) steady state and transient reactance, given in % to define generating sets. 13 GE Consumer & Industrial Industrial Components Team
ProceraPlus Project Started – Source Power Standarised power of the source characteristics are given from a file . Power value can be entered as "not normalized" if Ukr was chosen 14 GE Consumer & Industrial Industrial Components Team
ProceraPlus Project Started – Number of Sources In ProceraPlus, all sources are considered as identical. This data is used to determine Ikmax, which makes it possible to propose downstream protective device in case of paralleling of several transformers. Ik mini are calculated taking into account the minimum number of sources in parallel. 15 GE Consumer & Industrial Industrial Components Team

ProceraPlus Creating Project – Using Tabs Impedance Tab Loop impedances upstream MSB and related to one single transformer. These values are the sum of impedances. . 26 GE Consumer & Industrial Industrial Components Team
ProceraPlus Creating Project – Using Tabs Impedance Tab R0 Phase-Phase - Loop resistance Phase to Phase (equals to 2 times one phase resistance), calculated at 20°C conductors temperature. This value is used to determine the maximum short circuit currents (Ik Max). R1 Phase-Phase Loop resistance Phase to Phase (equals to 2 times one phase resistance), calculated at operating temperature. This value is used to determine among others the minimum short circuit currents (Ik Min). X Phase-Phase Loop reactance Phase to Phase. This value is used to determine minimum short circuit currents (Ik Min). X Phase Phase reactance. This value is used to determine maximum short circuit currents. R0 Phase-Neutral Loop resistance Phase to Neutral, calculated at 20°C conductors temperature. This value is used to determine the maximum short circuit current (Ik Max SIngle).

ProceraPlus Creating Project – Using Tabs Board Tab • Ref mark Board Downstream Ref mark – Editable • Designation Board name (data recommended for ease of identification). – Editable • Coincidence factor (K.Simultaneity) Simultaneity factor for circuits fed by the considered board. - Editable Example : a distribution feeds 10 circuits of 10 Amps each. A Simultaneity factor of 0.8 means that the total real consumption is 10 x 10 x 0,8, to say 80 Amps. • Earthing system Board Earthing system : TT, TN, IT • Voltage , No load voltage No load voltage in V, used to calculate Ik3 Max. • Upstream circuit ref mark Circuit Upstream ref mark. In case of an installation with a standby, the board can be fed by two different circuits. An upstream circuit supplied from the normal supply and another one from the standby source supply. • Breaking device Board breaking device (generally a switching device in distribution boards). - Editable 28 GE Consumer & Industrial Industrial Components Team
