MEASURES
–   The DCRL8 provides a set of measurements displayed on the alphanumeric display, in conjunction with the current cosphi that is always displayed on the main display
–   Press the MODE key to scroll through the measures in rotation
–   After 30 seconds without pressing any buttons, the display automatically returns to the default measurement defined by P.47
–   If P.47 is set on the ROT, then the measures rotate automatically every 5 seconds
–   At the bottom of the list of measures it is possible to set the setpoint of the cosphi, acting on the same value set with P.19.
Below is a table with the measurements displayed.

DESCRIPTION

Delta-kvar

kvar

Kvars needed to reach the cosphi setpoint. If delta-kvar is positive cpacitors need to be inserted, if negative to be disconnected.

kvar

Total kvar of the plant.

STEP

Number of equivalent steps.

Voltage

V

RMS voltage of the plant current.

V HI

Maximum peak of measure.

Current

A

RMS current of the plant voltage.

A HI

Maximum peak of measure.

Weekly PF

WPF

Weekly average power factor.

PF

Instantaneous total power factor.

Cap. current

%C.CU

Calculated capacitor current, in % of their nominal.

%C.HI

Maximum peak of measure.

Temperature

°C  °F

Temperature of internal sensor.

°CHI

°FHI

Maximum peak of measure.

Voltage THD

THDV

Total harmonic distortion % (THD) of plant voltage.

VH02…

...VH15

% voltage harmonic content from 2.nd up to 15.th order.

Current THD

THDI

Total harmonic distortion % (THD) of plant current.

IH02…
…IH15

% Current harmonic content from 2.nd up to 15.th order.

Cosphi setpoint

IND CAP

Setting of desired cosphi setpoint (same as P.19).

Step power

%

Step residual power, as a percentage of the set rated power.

Step counter

OPC

Operation counter of the step. 

Step hours

H

Hour meter of the step insertion.

 

These measures are shown only if the Step trimming function is enabled (P.25=ON)  and the advanced password is enabled and entered.
