  • Page 15: Section Igeneral Information

    We are confident you will be delighted with the unit's unique analyzing capabilities, as well as its ability to download events to a disk for permanent storage and later recall. The 658 is a powerful, self-contained, portable instrument that captures, records, analyzes, and displays AC and DC power line disturbances on four power acquisition channels.

  • Page 16: Applications And Purpose

    400 Hz waveforms may be analyzed also. The 658 Power Quality Analyzer can be used to view all data recorded on a Model 656 or 656A. However, the reverse is not true, unless the 656A is operating with version 3.0, or greater, of the Operating System.

  • Page 17: Using The Cursor Keys, Dedicated Keys, Alphanumeric Keys, And Zoom Feature

    Feature The cursor keys, dedicated keys, and alphanumeric keys are used to select menus and menu options throughout the operation of the 658. The cursor keys are primarily used to select menu and menu options due to their simplicity in movement to select either horizontal or vertical items.

  • Page 18: Distinctive Operation

    Another distinctive feature of the 658 is that it monitors RMS disturbances on a cycle by cycle (50/60 Hz) basis, rather than averaging multiple cycles as other waveform analyzers might do.

  • Page 19: Overview Of Operation

    The 658 is designed for easy operation. All selections and entries are prompted by the display, and the Operator is never more than a keystroke away from a "Help" screen. This lets you run the 658 without having to continually refer to this manual for instructions.
  • Page 20 1.4.3.4 Monitoring Status Screen and the Initial Reference Readings When you turn on the 658, you'll hear beeps indicating that the power on event, main channel waveform(s), RMS, and frequency events have been recorded. The first display shown after power turn-on is the Status Screen shown below. This screen provides the current date and time and monitoring information on the RMS values and frequency of the four main channels;...
  • Page 21 1.4.3.5 Event Recording Other than the standard events recorded when the 658 is first turned on, events are also recorded with any of the following occurrences: NOTE RMS voltages and currents are calculated on a single cycle basis from one positive zero crossing to the next positive zero crossing.

    TM-115000-G1 658 units have a screen blanking feature. If the keyboard is not used for a period of five minutes, the screen goes blank. The image resumes as soon as any key on the keyboard is pressed This feature helps to preserve screen life and save power consumption. The screen is also blanked when the unit is running on its internal battery.

  • Page 31: Battery Pack

    Refer to Table 1-1 for technical specifications. Four rear panel voltage inputs and 3 rear panel current inputs allow the 658 to analyze synchronous, multiphase AC power lines of up to 600 V RMS and 5, 30, 300, or 3000 A RMS (depending on your choice of current probes).

    Sensor (Transducer) Channel Setup screens, Figure C-2. The setup number corresponding to each screen is displayed in the upper left corner. Each of the 16 default setups stored in the 658 memory corresponds to a particular circuit monitoring application. A sampling of some of the setups are described in paragraph 2.4.5.3. The following list identifies which default setup to use for each circuit type.

  • Page 181: General

    Although harmonic analysis can be performed on any complete cycle, harmonics only cause damage when they exist for a significant length of time. Since the 658 records an event when the waveform deviates (by more than the user set sensitivity) from the last cycle in the previously recorded waveform event, the cycle to cycle repetition of the harmonic distortion does not cause additional events to be recorded.

  • Page 182: Damage From Harmonic Disturbances

    TM-115000-G1 to understand the following: • If the initial waveform event captured by the 658 is distorted, and no other waveform events are recorded for a period of time, it means that there was no significant change in the overall waveshape from cycle to cycle.

  • Page 183: Possible Causes Of Harmonic Distortion

    TM-115000-G1 Current harmonics tend to be less severe further from their point of origin. Voltage harmonics, on the other hand, have a tendency to propagate and disperse throughout the system, and can therefore cause damage and other problems at great distances from their point of origin. POSSIBLE CAUSES OF HARMONIC DISTORTION Often equipment causing harmonic distortion is bought in small quantities.

  • Page 184: Normalizing The Phase

    Once the existence of harmonics has been confirmed, the source of the disturbance must be determined. With the 658 Analyzer connected to the power line, take a steady state reading with the suspected source on and again with the suspected source off. (If the equipment is capable of...
  • Page 185 If the load changes, the filter may have to be redesigned. The 658 clearly indicates the most offensive harmonic frequencies along with their contribution to the total harmonic distortion. This information is important when designing the filter.
