Fluke 1735 Power Analyzer

  1. 1. Fluke 1735 – The Electrician’s Power Logger
  2. 2. Target Customers <ul><li>Electrical Contractors / Installers </li></ul><ul><li>Designed for field use, the 1735 is the perfect tool for conducting </li></ul><ul><ul><li>Load Studies verify electrical system capacity before adding loads (according to NEC standard) </li></ul></ul><ul><ul><li>Energy Assessments quantify energy consumption before and after improvements to justify energy saving devices </li></ul></ul><ul><ul><li>Harmonics Measurements uncover harmonic issues that can damage or disrupt critical equipment </li></ul></ul><ul><ul><li>Voltage Event Capture monitor for dips and swells that cause spurious resets or nuisance circuit breaker tripping </li></ul></ul>
  3. 3. National Electric Code 220.87 <ul><li>National Electric Code </li></ul><ul><li>220.87 Optional Calculations for Determining Existing Loads. </li></ul><ul><li>The calculations of a feeder or service load for existing installations shall be permitted to use actual maximum demand to determine the existing load under the following conditions: </li></ul><ul><ul><li>The maximum demand data is available for a 1- year period. </li></ul></ul><ul><li>Exception: If the maximum demand data for a 1-year period is not available. The calculated load shall be permitted to be based on the maximum demand (measure of average power demand over a 15-minute period) continuously recorded over a minimum 30 day period using a recording ammeter or power meter connected to the highest loaded phase of the feeder or service, based on the initial loading at the start of the recording. </li></ul><ul><li>The NEC Handbook further clarifies demand to mean kVA versus kW as stated below. </li></ul><ul><li>Additional loads may be connected to existing services and feeders under the following conditions: </li></ul><ul><ul><li>The maximum demand kVA data for a minimum one-year period (or the 30-day alternate method from the exception) is available. </li></ul></ul>
  4. 4. NEC Load Study Opportunity <ul><li>Large Electrical Contractor in Detroit </li></ul><ul><ul><li>10th largest contractor in USA </li></ul></ul><ul><ul><li>300 electricians,   </li></ul></ul><ul><ul><li>100 Power Loggers purchased in 2002 to conduct load studies as additional service to customers </li></ul></ul><ul><ul><li>After 3 years, only 50 remain…the others were left behind or stolen </li></ul></ul><ul><li>Every electrical contracting firm owns products for NEC 30-Day Load Studies </li></ul>
  5. 5. <ul><li>Color display for easy setup and verification </li></ul><ul><li>Four included triple range flexible current probes with no battery required </li></ul><ul><li>Easy-to-use analysis and reporting software </li></ul><ul><li>Affordable price point for simple 3-phase power quality measurements </li></ul>1735 Power Logger Why choose the 1735?
  6. 6. Compact rugged design to IP65 with 16 hour battery life for field applications Records all variables with 1 second to 20 minute averaging Measures voltage, current, power, energy, harmonics and voltage events General purpose, entry level, three phase power analyser Three phase voltage and four current inputs with full range of probe accessories The entry level power, harmonics and event logger 1735 Power Logger
  7. 7. Easy to use and setup with simple rotary switch Large, bright colour display (320 x 240 pixels) Save up to 50 screen snapshots and 999 events Voltage & Current measurements, Waveforms, Harmonics, Power and Voltage Events Measuring cursor for active measurements Records for over 30 days with 15 minute averages – as required by NEC 1735 Power Logger
  8. 8. Direct display of all power parameter totals Flexible Energy measurement and totalization Easy setup and measurement on installed CT‘s ‘ On the Fly’ changes, screen save, download etc. View trends while logging data 1735 Power Logger
  9. 9. One click to download and display Simple Tab view for easy access to recorded values Clear, display of RMS values Screenshot Tab to see capture screens Easy zooming PowerLog Software for 1735
  10. 10. One click to export measured data On-line virtual demo available Automatic Reports from ‘File’ menu PowerLog Software for 1735
  11. 11. Supplied with four phase for currents up to 3000A Complete with all accessories including carry case Rugged rubber holster One step download, analysis and reporting software – PowerLog Includes universal power supply adapter 1735 Power Logger
  12. 12. The only instrument with colour display in this class of instrument Volts, Amps and Frequency measurements Voltage and Current Waveforms & Frequency Voltage and Current Harmonics Power Parameters W, VA, kVA, kVAR, kWHr and kVARh Voltage events dips, surges, interruptions etc. Recordings Are shown ‘ LIVE’ on the display 1735 Power Logger
  13. 13. Oscilloscope Mode 1735 Power Logger View all three phases of voltage and current simultaneously for quick check voltage and current balance and correct connection Drill in to individual phase detail to check voltage / current phase difference and waveform distortion – Phase A Drill in to individual phase detail to check voltage / current phase difference and waveform distortion – Phase B Drill in to individual phase detail to check voltage / current phase difference and waveform distortion – Phase C Check distortion of neutral current – an indicator of the presence of distorting electronic loads Screenshots can be saved in the instrument, downloaded by PowerLog software and pasted in to any document
  14. 14. Harmonics Measurement 1735 Power Logger Instantly view harmonics as they happen – Phase A voltage harmonic Instantly view harmonics as they happen – Phase B voltage harmonic Instantly view harmonics as they happen – Phase C voltage harmonic Instantly view harmonics as they happen – Phase A current harmonic Instantly view harmonics as they happen – Phase B current harmonic Instantly view harmonics as they happen – Phase C current harmonic Instantly view harmonics as they happen – Neutral current harmonic – another indicator of the presence of distorting electronic loads
  15. 15. Harmonics Recording 1735 Power Logger Record harmonics over time to view trends - Record harmonics over time to view trends - programmable recording times from 2 hours to 45 days Trend is drawn graphically on screen for quick evaluation and long term analysis After some time the graph moves along the window and a ‘slice’ of the recording is visible on the display. The width of the ‘slice is dependant on the average time selected This mode can be used for ‘harmonic benchmarking’ -that is the comparison of electrical systems after installation of new, possibly disturbing harmonic loads. Logged data can be downloaded by PowerLog software for further analysis and automatic reporting
  16. 16. Measure Energy Consumption Pressing the down Cursor key from the power screen takes the user to the energy screen - Press <RUN> to start measuring 1735 Power Logger

  20. 20. Capturing Voltage Events 1735 Power Logger Voltage events are considered to be one of the main cause of disruption to electrical systems. These voltage events are classified as: Dip / Sags – A fall in nominal operating voltage by more than 10% for at least half of one frequency cycle Swell / Surge – A rise in nominal operating voltage by more than 10% for at least half of one frequency cycle Interruption – A complete loss of voltage for at least half of one frequency cycle
  21. 21. Capturing Voltage Events 1735 Power Logger A threshold for voltage event capture is set – this is normally a percentage of the nominal operating voltage If threshold is exceeded the event is captured and displayed, often many events occur almost simultaneously for example: across more than one phase or a short dip and return to nominal level The capture event is noted by type, location and includes real trigger time Subsequent events can be viewed by scrolling through events data with cursor pad
