Report name: The user can enter the name of the file for identification purposes. This field is
limited to 16 characters. For example, the user can enter the name of the place where the
measurements are going to be taken.
Register period: This field states the recording period. The value ranges from 1 to 120 minutes
(2 hours) and it corresponds to a time interval during which we use to store the average of
the records taken. The analyzer takes 128 samples per cycle of the signals measured. The
registration period indicates the interval desired to take the weighted mean of all samples
taken and it stores this value in the memory. For example, if the user select a recording
period of 1 minute, the analyzer calculates the mean of all samples of the variables recorded
during that minute and stores the results in the memory. From that period, the analyzer also
stores the maximum and minimum values measured.
Primary voltage: When using transformers to measure the voltage, enter the primary voltage
value of the transformer. The information related to this feature of the transformer can be
founded on a features label of the transformer. This label must indicate the primary ratio. In
case you are not using voltage transformers and you are taking a direct measurement (up to
400 V p-n), the value entered must be 1.
Secondary voltage: When using transformers to measure the voltage, enter the secondary
voltage value of the transformer. The information related to this feature of the transformer
can be found on a features label of the transformer. This label must indicate the secondary
ratio. In case you are not using voltage transformers and you are taking a direct
measurement, the value entered must be 1.
The voltage transformer ranges and transformer ratio have certain limits given
below:
1º. Primary voltage range between 1 and 220.000
2º. Secondary voltage range between 1 and 999
3º. Primary/secondary ratio between 1 and 10.000
6.3.2.2 Selection of the current transformer ratio.
This option must be selected in case of using CP-5 current clamps which have a nominal
secondary current of 5A and are designed to work with a shunt resistor giving 2V at the
instrument input.
Primary current: In this field, the user must program the rated primary current of the current
transformer (CT). The maximum value in this field is limited to 10.000 (The user must check
that the measured power limit is less than 70.000.000W).
Secondary current: The default value for the CP5 current clamp is a secondary current of 5 A
Nominal rated voltage (Ph-Neutral): In this field the user must introduce the nominal voltage
between phase and neutral. The allowed range is 50…400V. In case of using a voltage
transformer to measure the voltage (HV installations), the value introduced in this field must
be the nominal value of secondary of the measuring transformer.
Nominal Freq.: Enter the nominal value of the installation's frequency. The values allowed for
this field are 50 or 60 Hz.
Contracted power (kW): The contracted or “demand power” is usually employed to calculate a
“Minimum Charge” in the electricity bill. The term has very different meanings in different
countries and in the CIR-e
3 is used only for information purposes and does not have any
impact on the unit's configuration.
