MEMORY HiCORDER 8807-51, 8808-51 Recorders Instantaneous Analysis and Long-term Recording of Harmonic Waves for Maintenance of Commercial Power Systems Are the harmonics in your company's power lines in order? The new 8807-51/8808-51 is an economical tool that will clearly identify and analyze the current harmonic state of your power system. To the 8807- 01 /8808- 01 MEMORY HiCORDERs with their popular detachable printers, HIOKI has added the 8807- 51/8808- 51 MEMORY HiCORDERs with harmonic analysis function. Capable of both instantaneous analysis and time series analysis of harmonics, these units can measure and analyze harmonic current flowing into and out of a commercial power system, as well as harmonic components piggybacking on power line voltage. Instantaneous harmonic analysis Time series recording • Can measure harmonics up to 40 orders from the fundamen-tal wave • Analysis display includes RMS value, content factor, phase angle, active power, and power phase angle for each order of harmonics (numeric and graphic display) • Analysis display of total RMS value, total distortion, active/ reactive/apparent power, and power factor (numeric display) • Bar graph and numeric data display • Power phase angle can be displayed as a vector • Harmonic analysis of up to 20 items • Data recorded in time series • When analyzing four items simultaneously, data can be recorded for up to 150 days Flexible connection options • Supports independent channels, singlephase two-wire, single-phase three-wire, and three-phase three-wire • Full isolation of all analog channels Useful measurement functions • Connection check • Level check • Over-range function Waveform Direct read-out of current through general-purpose clamps Bar graph Numeric data Power vector • Compatible with HIOKI's 9018-10 and 9132-10 CLAMP-ON PROBE This catalog is dedicated to featuring the harmonic wave analysis functions of Models 8807-51 and 8808 -51, functions that are not included in the standard Models 8807-01 and 8808 -01. As the waveform recording functions of Models 8807-51 and 8808 -51 are identical to those of Models 8807-01 and 8808 -01, please refer to the catalog for the latter models for detailed descriptions. 2 Use the 8807-51, 8808-51 to determine the current - Harmonic Wave Functions Harmonic wave instantaneous analysis mode T h e 8 8 0 7- 5 1 a n d 8 8 0 8 - 5 1 c a n a n a l y z e harmonic components (up to 40 orders from the fundamental wave) that are included in voltage and current in a power line with a base frequency of 45 to 65Hz. Based on the waveform that was captured, the 8807- 51 and 8808- 51 can analyze the RMS value, content factor, phase angle, active power, and power phase angle for each order of harmonics. The measurement results can be displayed and recorded as a bar graph, numeric data, or power vector diagram. The 8807- 51 and 8808- 51 can also display numerically the total RMS value, the total distortion, the active/ reactive/apparent power, and power factor. ▲Captured Captured waveform (waveform display screen) ▲RMS value of harmonic wave (bar graph) ▲Content factor of harmonic wave (numeric data) Time series analysis mode for continuous measurement of changes in harmonics This mode is used to continuously measure changes in the RMS value, content factor, phase angle, active power, and total distortion for each order of harmonics. Measurements are made at specific intervals and are displayed and recorded as a graph. Through long-term monitoring of the correlation between the timing of harmonic waves and their relationship to phenomena, the 8807- 51 and 8808- 51 become useful tools for finding the causes of harmonic interference and taking appropriate action. Time series graph display screen In time series recording mode, the 8807- 51 and 8808- 51 are capable of recording up to 20 harmonic wave analysis items simultaneously. The recording time can be set over a range of 30 minutes to 150 days and the data is stored in internal memory. If "continuous" is set as the recording time, the 8807- 51 and 8808- 51 are able to draw a continuous graph on recording paper. Only the measurements for the last 60 divisions are stored in internal memory. Harmonic analysis item settings ▲Time series analysis printout example This time series graph shows four of the analysis items that were recorded. 3 state of harmonic waves Harmonic wave power measurement on single-phase two-wire, single-phase three-wire*, and three-phase three-wire* lines Determine the direction of flow of harmonic waves Power vector diagram Power content factor (bar graph) The 8807-51 and 8808-51 both allow you to input voltage on channels 1 and 3 and current on channels 2 and 4 (through the clamp-on probe) and then display a power vector diagram for each harmonic wave. This diagram can then be used to determine whether the harmonic waves are flowing from the power supply system or from the load. The 8 8 0 7 - 5 1 and 8 8 0 8 - 5 1 are both capable of measurement of single-phase two-wire lines, while the 8808- 51 is also capable of measurement of single-phase threewire*, dual single-phase two-wire*, and three-phase three-wire* lines. Both units can display numeric data or a graphs for the active power, active power content factor, and power phase angle for each order of harmonics. Because all analog input channels are isolated, no problems are encountered when measuring two different single-phase twowire systems simultaneously, or if connections are made incorrectly. **8808-51 only - Product Specifications - Note: The waveform recording functions of the 8807-51 and 8808-51 MEMORY HiCORDERs are identical to those of the 8807-01 and 8808-01 MEMORY HiCORDERs.
