Nameplate Power

Nameplate Power

Nameplate Power has a unit value of Power kW.

Other unit options such as hp can be added to the project via the grid configuration facility in the Configuration module.

Nameplate Efficiency

Nameplate Efficiency has a unit value of Ratio.

Nameplate Power Factor

Nameplate Power Factor has a unit value between 0 and 1.

Nameplate Power Factor Unit

Nameplate Power Factor Unit can have values of LEAD and LAG.

• When value is set as LAG then Nameplate Reactive Power is positive.

• When value is set as LEAD then Nameplate Reactive Power is negative.

• If Nameplate Power Factor =1 then Nameplate Power Factor Unit will be set to null.

Nameplate Electrical Power

Nameplate Electrical Power has a unit value of Power kW.

It is calculated using this equation:

Nameplate Electrical Power = Nameplate Power / Nameplate Efficiency

Nameplate Reactive Power

Nameplate Reactive Power has a unit value of Reactive Power kVAr.

It is calculated using this equation:

Nameplate Reactive Power = Nameplate Electrical Power * √ ( (1- Nameplate Power Factor2) / Nameplate Power Factor2)

Note:
Positive Nameplate Reactive Power values are defined as LAG.

Negative Nameplate Reactive Power values are defined as LEAD.

Nameplate Apparent Power

Nameplate Apparent Power has a unit value of Power kVA.

Other unit options can be added to the project via the grid configuration facility in the Configuration module.

It is calculated using this equation:

Nameplate Apparent Power = √ (Nameplate Electrical Power2 + Nameplate Reactive Power2)

Nameplate Full Load Current

Nameplate Full Load Current has a unit value of Current A.

The Nameplate Full Load Current calculations below depend on the number of phases and therefore on the voltage type.

The equation for voltage is:

Line Voltage = Phase Voltage * √3

The equation for a single phase load i.e. Voltage Type = S, is:

Nameplate Full Load Current = (Nameplate Apparent Power * 1000) / Voltage (Phase voltage)

The equation for a 2 phase load i.e. Voltage Type = L, is:

Nameplate Full Load Current = (Nameplate Apparent Power * 1000) / Voltage (Line voltage)

The equation for a 3 phase load i.e. Voltage Type = TN, T, is:

Nameplate Full Load Current = (Nameplate Apparent Power * 1000) / (Voltage (Line voltage) * √3)

DC Calculations

DC calculations use the same equations as above except that Nameplate Power Factor = 0. This means Nameplate Power Factor Unit is null.

Calculation are as follows:

Nameplate Electrical Power = (Nameplate Power / Nameplate Efficiency)

Nameplate Reactive Power = 0

Nameplate Apparent Power = Nameplate Electrical Power

Nameplate Full Load Current = (Nameplate Electrical Power * 1000) / Voltage
