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.



ProceraPlus

• Cross section of conductors

• Fault levels

• Switchgear selection

• Draw single line diagram

ProceraPlus is a software to design & calculate



ProceraPlus

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.

There are three possiblechoices : • Transformer HV-LV • Genset • Direct supply from utility board (LV direct

Project Started – Type of Source



ProceraPlus

TransformerThey can be entered:

a) from a file giving sources impedances and standard Powers or,

b) from Ukr, short circuit voltagein % for transformers, equivalentto impedance

Project Started – Source Characteristics



ProceraPlus

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 definegenerating sets.

Project Started – Source Characteristics



ProceraPlus

Standarised power of the sourcecharacteristics are given froma file . Power value can be entered as "not normalized" if Ukr was chosen

Project Started – Source Power



ProceraPlus

In ProceraPlus, all sourcesare considered as identical. This data is used to determine Ikmax, which makes it possible to proposedownstream protective device incase of paralleling of several transformers. Ik mini are calculatedtaking into account the minimumnumber of sources in parallel.

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).

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.

•A UPS can be connected either on a Normal or Standby distribution. •A comparison between Ik is done to keep the least favorable one (Ik max on the network, Ikmin on the UPS). The process is inverted when Normal source Ik Min become less than UPS ones. UPS are considered as current generators. Due to that, Ik are unchanged along the network tree. The UPS is always considered as connected in "By-Pass"mode.

ProceraPlus Creating Project – Source Has Been Defined



ProceraPlus

Mains (N) & Stand-by (S) source have been defined

Creating Project – Types of Source(Mains and Stand-by)



ProceraPlus

Next step: Adding next subboards

Besides choosing standard parameters it must be specified if the load ( board) will be fed from Stand- By Supply.

Since Stand by Supply usually has much less SC current – The crtiterion that Imag< ISC_min must checked as well. The max setting of Imag is given.




ProceraPlus

NS on crossing indicates that subboard is fed from Mains or Stand ByN- fed only from Mains




ProceraPlus

Results for Board which can be suplied from NS.Since SC currents are smaller in case when fed from Stand By –the minimum Isc which can appear is 4260A.

The value assumes the tolerance3550 *1,2=4260




ProceraPlus

When board is fed only from Mains ( there is not possible situation to be fed from Stand by only) the magnetic settings can be much higher.

For the same board and cable in this case the max Imag could be equal even 14272A

Is the result OK for you?

If NOT “up” or “down” stream breaker must be changed.

To choose breakers assuring total discrimination/ selectivitypress button as on drawing or F12

ProceraPlus

Changing upper and lower breakers type change the achieved discrimination results.

Thus the upper breaker should be changed to for instance K frame SMR1e.




ProceraPlus

After changing the upper stream breaker

The lower part of diagram is in red- it must be recalculated




ProceraPlus

The total discrimination is assured

In the same way adding next circuits the project is designed

ProceraPlus

For given example despite the fact that the I3max on DB2 is 34kA, the end load circuits are protected with cost effective 25kA MCCBs.This effect is achieved thanks to backup backup protectionprotection.
