Reactive power
Power that does not perform actual work, resulting in power consumption
as it travels between the load and the power supply. Reactive power is cal-
culated by multiplying the active power by the sine of the phase difference
(sin

). It arises from inductive loads (deriving from inductance) and
capacitive loads (deriving from capacitance), with reactive power derived
from inductive loads known as lag reactive power and reactive power
derived from capacitive loads known as lead reactive power.
Reactive power
demand value
The average reactive power used during a set period of interval time (usu-
ally 30 minutes).
RMS value
The square root of the squares of 1,024 sampling points in a 200 ms inter-
val. The value includes harmonic components.
SD memory card
A type of flash memory card.
Text data
A file containing only data expressed using characters and character
codes.
USB
An interface that allows data to be sent to and received from a host con-
troller (usually a computer) to which a device is connected with a USB
cable. Consequently, functions are unable to communicate directly.
Zero suppression
Functionality for treating values that are less than a certain threshold as
zero.
