Calibration Eletric Power Standard Fluke 6100A |
 |
Comprehensive Functionality
As an Electrical Power Standard, the 6100A has been designed to produce a comprehensive array of electrical power signal types to a very high degree of accuracy. This can be achieved over 1, 2, 3 or 4 phases independently and simultaneously depending on system configuration.

Phantom power
The 6100A will supply pure sinusoidal voltage to 1000 V and current to 21 Amps (optionally to 80 A). Up to 50 VA's of power is available from the voltage terminals to support instruments which draw power from the line on which they are measuring. Up to 14 V of compliance is available from the current output to ensure current is delivered in setups involving long cable runs, connectors and switches, or where multiple instruments are connected in series. The current output can also produce an auxiliary voltage of up to 10 V in order to simulate signals that may be produced by transducers or current probes. Phase angle between voltage and current, and between multiple phases, is fully adjustable by the user from -180 degrees to +180 degrees. In addition to the values of V, I and phase angle set by the user, the on screen display shows calculated values of real power (W), apparent power (VA), various representations of reactive power and power factor (PF) |

Multi-phase operation
The 6100A Master unit offers self-contained single phase operation, with one voltage and one current output. For multi-phase applications, the addition of one or more 6101A Auxiliary units provides additional phases, with identical performance but without the overhead and additional complexity of an additional set of controls and display. Additional phases can be added individually until a maximum of four phases is reached. In multiphase systems, each phase remains totally independent and completely electrically isolated, yet synchronized with, and under the control of the master unit. In multi-phase work, current and voltage on each phase is independently programmable, allowing the user to simulate unbalance conditions.

Energy calibration and verification
The Fluke 6100A's energy option provides full functionality for work with energy (watthour) meters, and supports a number of methods of working, depending on the users preference and the availability of external references and other equipment. For full functionality, the 6100A is equipped with inputs to receive calibration pulses from the meter or meters under test (single or multiphase). The 6100A is then able to calculate energy recorded by the meter (according to the meter constant entered by the user), compare this against energy it has delivered, then calculate and display errors. If the user prefers to use an external comparator, the 6100A is equipped with pulse outputs. These provide pulses proportional to energy delivered, again according to the meter constant entered by the user. These pulse streams can then be compared against equivalent pulses from the meter under test by the external comparator. |

Complex signals
In addition to sinusoidal voltages and currents, the 6100A can supply accurate amounts of harmonic distortion independently on the voltage and current outputs. All of the first 100 harmonics can be set individually by the user, with levels of up to 30 % of the fundamental value, theamplitude and phase of each harmonic are independently controllable by the user. A dc level is also programmable. Addition of harmonics does not significantly impair accuracy or compromise traceability of the measurement. This unique capability means that test protocols using specific waveshapes such as those defined by IEC 61036 for energy meters can now be implemented with ease, and with high levels of confidence and accuracy. |

For more complex work, the 6100A will also generate flicker (compliant to IEC 61000-4-15), interharmonics (compliant to IEC 61000-4-7), and fluctuating harmonics. Dips and swells from 0 % to 140 % can be individually programmed on voltage or current, or both. Dips and swells can be sub-cycle (from around 1 milli-second) out to 1 minute in length. Most of these signal types are available simultaneously, so that very complex scenarios are possible. This not only simulates "real world" conditions, but is also a requirement of new standards defining power quality measurement methods such as IEC61000-4-30. The Fluke 6100A enables full compliance to this international standard. |
User Interface
The user interface of the 6100A is critical to allow users to exploit its extensive capabilities. To ensure simplicity of operation, a Microsoft Windows® user interface has been adopted. The interface can be accessed through a combination of front panel knobs and buttons, an optional mouse and keyboard and a high resolution, 9-inch TFT display. Status information of all four phases is displayed, alongside more detailed information on current parameters being set or adjusted. Frequency domain and time domain representation of current signal types can be displayed on the screen so that the user is able evaluate the effect of control settings before applying the signal to the output terminals of the 6100A. At the bottom of the screen a context sensitive help window further guides the operator through instrument setup by providing additional control information and error messages. |
Automation
Instrument setups can be saved and recalled within the instrument or on floppy disk. This provides one route for automating complex tasks. A series of complete instrument setups can be stored, and recalled under user or computer control, thus producing a sequence of steps, or test program. Additionally, the 6100A is compatible with Fluke's MET/CAL® metrology software package, allowing full automation in addition to a wide range of other functions such as inventory control. |
