The MC133 master unit
model is
a one phase electric power/energy calibrator. It can supply the
device under
test with one phase accurate AC voltage and current with calibrated
phase shift or DC voltage and current. Output voltage can be set in five
ranges up to 280V and output current in six ranges up to 30A. Simulated
electric power can be set independently in each phase. Frequency can be
set in range from 15Hz to 1 kHz with resolution 0.001Hz to 0.01Hz.
Calibrator is equipped with 5 1/2 digital DC meter with DC ranges 20mA
or 10V for direct calibrating of various types of power transducers.
The
MC133 calibrator offers two types of defined distortion of main
sinusoidal output signal. The first distortion is based on
adding a defined amount of harmonic or inter-harmonic spectral components
up to 5kHz. The second type of distortion is based on amplitude
modulation of output sinusoidal signal by sin or square-wave modulation
signal in frequency range from 0.001Hz to 50Hz. Maximum depth of
modulation is 30%.
Three-phase electric power/energy calibration system can be
optionally built-up using one MC133 master unit and two MC133f slave
units. The slave units contain power stages of each additional phase
output. They are fully controlled from master unit via rear panel
special interface. Maximum output voltage between two voltage phases is
560VAC. Current outputs can be joined together offering total range to
90A AC/DC. |

| Accuracy
of power factor: dPF = (1-cos(φ+dφ)/cos(φ) |
|
DC/AC Power (sine mode) |
Accuracy of power is calculated from value
of voltage, current and power factor. |
|
|
| |
Active power (W): dP = square root (dU2 + dI2 + dPF2 + 0.012)
[%]
Reactive power (VAr): dP = square root (dU2 + dI2 + dPF*2 + 0.012)
[%]
Apparent power (VA): dP = square root (dU2 + dI2 + 0.012)
[%] |
| |
Where:
- dP is accuracy of power [%]
- dU is accuracy of voltage [%]
- dI is accuracy of current [%]
- dPF is accuracy of power factor (cos φ) [%]
- dPF* is accuracy of sin φ [%]
