The Fluke 6100A Electrical Power Standard The most accurate, comprehensive and flexible source of electrical power signals Measurement validation for electrical power applications The importance of accurate measurement of power Against this turbulent change, little progress has and energy has increased dramatically over a been made in the verification of these relatively short period of time. Deregulation and measurements. Instruments to be used to measure the increasingly distributed nature of the power and report precise parameters on power lines supply network mean that measurements are made carrying significantly distorted, noisy and more frequently, and a higher degree of accuracy fluctuating voltages are verified and calibrated is required as previously acceptable levels of error under laboratory conditions. Pure, noise free, begin to compound. leveled sinusoidal voltages and currents are still routinely applied as reference signals. At the same time, the environment in which In the field of new measurements and new these measurements are being made is instrument types, the situation is even worse. Some becoming increasingly hostile to good of the more complex measurements have few measurement practice. Harmonic distortion, standards or protocols which define precisely how voltage fluctuations, phase imbalances and they should be made, and there are no real other extraneous, re-injected signal components solutions to the problems of how to verify the provide an alien environment for measurement measurement, or how to calibrate the instrument devices designed to operate primarily on making it. Perhaps it’s unsurprising that different sinusoidal signals. measurement techniques and different instruments yield different results on what is ostensibly the Additionally, many new measurement and same measurement, or that measurement instrument types have arisen in an attempt to fully traceability often stops at the manufacturer. characterize network performance, and the nature of the product delivered – electricity. Flicker and Predictably, concern is increasing globally about harmonic measurements are becoming as the acceptability of this situation. commonplace as power factor measurements were a few years ago, and even more complex Against this background, Fluke has developed the measurements such as inter-harmonics are now 6100A Electrical Power Standard. relatively routine. 2 Comprehensive functionality Who needs a 6100A? Validation of electrical power measurements and the equipment that make them is required in many disciplines: • In design engineering to guarantee that measurements are being made correctly and accurately • In manufacturing test to make certain that measurements are correct and repeatable on every unit manufactured • In service and calibration to ensure that instruments continue to perform to specification throughout their lifetime • In standards laboratories to ensure measurement techniques and equipment meet appropriate standards. The 6100A provides the signals to allow this process to be completed effectively, quickly and easily. More importantly, it ensures that the process of validation is completed thoroughly, accurately and with all measurements being traceable to national standards. The 6100A was 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 20 Amps. 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 is also able to produce an auxiliary voltage in order to simulate signals that may be produced by transducers or current probes. 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), reactive power (VAR). and power factor (PF). Reactive power for non-sinusoidal signals is calculated by the 6100A using any of seven user selectable methods. In this mode of operation the 6100A can be used to calibrate or verify measurement of power,VA,VAR, phase angle, power factor, voltage and current on single or multi-phase instruments. Resolution and accuracy The Fluke 6100A sets a new benchmark for short term stability to 200 micro-degrees. In accuracy in power standards.Voltage and current multi-phase systems phase accuracy between are generated with up to 6 digits resolution and phases is down to 5 milli-degrees, again with accuracies approaching 100 ppm (0.01 %). Phase short term stability to 200 micro-degrees. This adjustment provides for 1 milli-degree or 10 outstanding level of phase performance equals micro-radian resolution. Phase performance is or exceeds a number of commercially available exceptional, with accuracy to 3 milli-degrees and phase standards. 3 Complex measurements Flicker Flicker is a complex measurement which sets out to measure the “annoyance factor” of a flickering light caused by modulation on its supply voltage, which is in turn caused by events such as large loads switching. The measurement is defined by IEC standard IEC- 61000-3-3. In simple terms, the measurement of flicker is a combination of two variables, amplitude and frequency of modulation over a period of time, (ten minutes to produce the so called Pst or short term flicker severity value). The 6100A simulates flicker by modulating voltage amplitude at a depth and frequency set by the user. The Pst value of this combination is calculated and displayed on screen. Harmonics 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. Addition of harmonics does not significantly impair accuracy or compromise traceability of the measurement. This mode of operation can be used to calibrate or verify measurements made by devices such as harmonic analyzers, power loggers, disturbance analyzers, etc. It is also valuable in ensuring that simpler measurements such as voltage, power or power factor are performed correctly and accurately under non-sinusoidal conditions. 4 Complex measurements Interharmonics Interharmonics are continuous signal elements unrelated to the fundamental frequency. For example, in a 60 Hz supply system, 180 Hz is a harmonic (the 3rd) but 190 Hz is an interharmonic.The 6100A can generate two independent interharmonics at a user-definable level and frequency on both the current and voltage outputs.With this function, the 6100A can simulate interharmonics caused by imperfect loads, or deliberately induced signals such as power line carrier signals. Fluctuating harmonics Fluctuating harmonics are individual harmonics which are amplitude modulated.The 6100A is able to individually modulate from one to all of the currently defined harmonics at up to 30 % of its nominal amplitude with a frequency of up to 30 Hz, and with a sinusoidal, square or rectangular waveshape. Dips and swells Output voltage or current can be caused to dip to a level below nominal or swell to a level above nominal for a period of between half a cycle and one minute. Ramp in and ramp out times, period, repetition delay and dip/swell level are all independently controllable. The dip or swell can be triggered internally to be synchronous with a preset value of phase of the fundamental, or triggered externally from another device. 5 Complex measurements Simultaneous application Full verification of complex measurement devices amongst other things, that measurement requires that complex combinations of signals are instruments are tested with compound signal handled correctly. This fact has been recognized types (for example flicker, imbalance and within the power measurement industry, and is harmonics all present) to ensure that performance being incorporated in IEC 61000-4-30 (Testing is maintained under real world conditions. The and measurement techniques – Power quality 6100A supports this need by making most signal measurement methods). This standard requires, types available simultaneously. Multi-phase operation The 6100A Master unit offers self-contained single a maximum of four phases is reached. In phase operation, with one voltage and one current multiphase systems, each phase remains totally output. For multi-phase applications, the addition independent and totally electrically isolated, yet of one or more 6101A Auxiliary units provides synchronized with, and under the control of the additional phases, with identical performance but master unit. This means applications where phase without the overhead of controls or display. imbalance or sequence errors are required are Additional phases can be added individually until simple and easy to arrange. User interface The user interface of the 6100A is critical to allow representation of current signal types can be users to exploit its extensive capabilities. To displayed on the screen so that the user is able ® ensure simplicity of operation, a Windows user evaluate the effect of control settings before interface has been adopted. The interface can be applying the signal to the output terminals of the accessed through a combination of front panel 6100A. At the bottom of the screen a context knobs and buttons, or by connecting the user’s sensitive help window further guides the operator own mouse and keyboard. Actions are then through instrument setup by providing additional viewed on the 6100A’s high resolution, 9-inch TFT control information and error messages. display. Status information of all four phases is displayed, alongside more detailed information Instrument setups can be saved and recalled on current parameters being set or adjusted. within the instrument or on floppy disk.
