GF101 Single Phase Electrical Power Calibrator With 0.05% Voltage &
Current Source WITH 0.05 CLASS POWER SOURCE
GF101 single phase voltage & current source is suitable for power
department, measuring department, quality control department,
research units, institution of higher learning, electric energy
meter, power distribution terminals, power supply management, load
control, power quality, reactive power compensation device and
production of the enterprise and so on. It can be as single phase
voltage source, current source and phantom load.
The GF101 AC Power Calibrator is equipped with RS232 PORT as
standard communication interface to control external devices
remotely. Power Factor Validation Power factor is an important
element when users judge the efficiency of a device.
In the Power Calibration mode, the GF101 can be used as a source to
calibrate DC and single-phase AC watt meters, power analyzers, and
energy meters. In this mode, the output voltage can be set up to
500V, the output current up to 120A, and the power factor from -1.0
to +1.0 lead/lag in the frequency band from 40Hz to 70Hz.
Voltage Source: A device which can produce a continuous force to move the
electrons (or, continuous voltage) through the wire connected into
the two terminals of the device is called a Voltage Source. There
are two types of the Voltage Source which are:
Direct Voltage Source:
A device which produces a continuous direct voltage output is
called a Direct Voltage Source. For example: Cells , Battery , DC
Generator.
A direct voltage is the kind of voltage whose polarity remains the
same. Direct Voltage causes the current to move only in one
direction continuously.
Alternating Voltage Source:
A device which produces a alternating direct voltage output is
called a Alternating Voltage Source. For example: AC Generator , DC
to AC converter etc.
A alternating voltage is the kind of voltage whose polarity is
reversed periodically. Alternating Voltage causes the current to
move in one direction for a period and then in another direction
for another period.
Current Source:
A current source is a device which provides the regular flow or
electrons or current on a circuit.
A current source is a type of voltage source which have enough EMF
and surplus electrons so as to produce the flow of electrons.
Direct Current Source:
The current source made of a Direct Voltage Source is called Direct
Current Source.
Alternating Current Source:
The current source made of a Alternating Voltage Source is called
Alternating Current Source.
Ideal Current Source:
A current source which provides a constant current without any
relation with the voltage supplied to the load is called Ideal
Current Source.
