On the "Loads" tab, make the following settings:
- The number of loads measured by module I-35
- For each load, the type of measured load
- For each load, the phase(s) on which the sensor(s) are connected
- For each sensor, you may need to adjust the direction of current in case of a wiring fault
The maximum number of loads for an I-3x current module is 3, because there are 3 sensor inputs
on this module.
The measured load type can be:
A single-phase load measured by 1 sensor (1P + N - 1CT)
A three-phase load without unbalanced neutral measured by 2 sensors (3P - 2CT), with the 3rd
current derived from a vector sum
A three-phase load with or without unbalanced neutral measured by 3 sensors (3P - 3CT or 3P +
N - 3CT)
A three-phase balanced load with or without neutral measured by 1 sensor (3P - 1CT or 3P + N -
1CT)
For a balanced load measured by a single sensor you can connect this sensor to any phase
The size of the sensor is always detected automatically and it is not possible to change it. The
only instance in which you will have to manually apply this value is if you are using an adjusting
sensor. In this case, you must send the rated current to the current transformer primary upstream
of the adjusting sensor.
