Using IntelliLink Software to Locate Problems
Line-to-Ground Voltage (var controls only)
This is the present value of the distribution line voltage (in kV), calculated based on the
Voltage Transformer Ratio
setpoint and
Voltage Transformer Wiring
setpoint, on the
Setup>Site-Related
screen.
Temperature
This is the present ambient air temperature. The temperature sensor is located on the bottom
of the control enclosure.
Neutral Sensor
For controls with neutral sensing, this is the present level of neutral current (in amps) or
neutral voltage (in volts) measured by the neutral sensor.
Control Time
This is the present time in the control.
Date
This is the present date in the control.
Last Switch-In or Last Switch-Out
These fields show the reasons for the last switch-in and switch-out event, for example
“Timeclock” or “Hardware Manual.”
1-Phase Current (var controls only)
This is the current (in amps), measured by the current sensor and scaled using the
Current
Sensor Ratio
setpoint.
Current Flow Direction (var controls only)
When the control is properly configured and power is flowing through the circuit in the
normal direction, this field displays “Normal.” If unusual circuit switching conditions cause
the direction of power flow to reverse, the field displays “Reverse.”
Corr. Phase Angle (var controls only)
This is the corrected phase angle, the offset of the current waveform referenced to the
voltage after setup correction factors are applied. When the control is properly configured,
the corrected phase angles will all be 0 ± 89.9 degrees.
Lagging phase angles are represented as values between 0 and 90 degrees. Leading phase
angles are represented as values between 0 and -90 degrees.
Uncorr. Phase Angle (var controls only)
This is the phase angle, the offset of the current waveform referenced to the voltage,
before setup correction factors are applied.
Power kvars (var controls only)
This is the total kvar level measured at the location of the current sensor, calculated as
3 times the single-phase kvar value. This assumes a balanced 3-phase system.
Power Factor (var controls only)
This is the power factor calculated as the cosine of the value in the
Corrected Phase Angle
field. Leading power factors are represented by negative numbers.
Power kW (var controls only)
This is the present kW level measured at the location of the current sensor.
Power kVA (var controls only)
This is the present kVA level measured at the location of the current sensor.
