GF303P smart phase angle adjustment 3 phase portable ac Electrical
Power Calibrator with Reactive power compensator
GF303P portable 3 phase ac Electrical Power Calibrator is suitable for power department, measuring department, quality
control department, research units, and institutions of higher
learning, and electric energy meter, power distribution terminals,
power supply management, load control, power quality, reactive
power compensation device and the production of enterprise etc.
The GF303P Electrical Power Calibrator is a powerful and portable
three phase current and voltage source. All test values are
generated absolutely synthetically with a high degree of accuracy
and stability. Following the different demands of customers, this
source is available in two versions, for the supply of transformer
meters with a maximum current up to 12 A as well as wider range
source up to 120 A. The GF303P portable Electrical Power Calibrator
may be used.
Power calibration at PF=0 (It measures Internal phase difference
between voltage and current input circuit.) Power calibration at
PF=1; Power calibration at PF=0. Calibration Method for working
standard at PF=0. Capacitor's Equivalent Circuit. Consumption power
of the resistor in the capacitor.
Power calibrators and power quality calibrators GF333V2 -
Three-phase Fully Automatic Test System with Reference Standard and
Integrated Current and Voltage Source The Calmet GF303P portable
test system consists of a three-phase reference meter of accuracy
class 0.04% (or 0.1%) and an integrated three-phase current and
voltage source up to 3x120A/600V
The GF303P electrical power calibrator can also be used to type
test 0.1% to 2% energy meters. Choose the GF302D electrical power
calibrator when you need the highest accuracy available for
calibrating secondary standard meters, energy revenue meters and
type test applications.
GF303P is electric AC/DC power and energy calibrator for
calibration of power meters, power transducers, power quality
analysers and generally all kinds of power measuring devices. AC
voltage, current, power and energy functions have calibrated phase
shift in frequency range from 45 Hz to 65Hz with resolution as good
as 0.001 Hz.
