The MC133C model is a compact one-housing three 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 1kHz 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.
MC133C calibrator offers two types of defined
distortion of main sinusoidal output signal. The first distortion is
based on adding 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 sine or square-wave
modulation signal in frequency range from 0.001Hz to 50Hz. Maximum
depth of modulation is 30%.
Using a supplied cable adapter the current outputs can be
joined together offering one phase current 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 [%]
