Energy logging is now within your reach— discover where you’re
wasting energy, optimize your facility’s energy use and reduce your
bill. Key measurements: voltage, current, power, power factor and
associated values enable energy saving strategies to be implemented.
• Bright, color touch screen: perform convenient in-the-field analysis and data checks with full graphical display.
• Comprehensive logging: all measured values are automatically logged
and can be reviewed during logging and before downloading for onthe- go
analysis. More than 20 separate logging sessions can be stored on the
instrument.
• Optimized user interface: quick, guided, graphical setup ensures
you’re capturing the right data every time, and the intelligent
verification function indicates correct connections have been made,
reducing user uncertainty.
• Complete ‘in-the-field’ setup through the front panel: no need to
return to the workshop for download and setup or to take a computer to
the electrical panel. Energy logging is now within your reach— discover
where you’re wasting energy, optimize your facility’s energy use and
reduce your bill.
• Wide range power: power instrument directly from the measured
circuit eliminating the need to find a power outlet while allowing the
instrument to be secured safely inside electrical panels.
• Two USB ports: one for PC connection and another for fast, simple download to standard USB thumb drives, or other USB devices.
• Compact size: designed to fit in tight spaces and panels.
• Highest safety rating in the industry: 600 V CAT IV/1000 V CAT III rated for use at the service entrance and downstream.
• Optimized measurement accessories: flat voltage cable and thin
flexible current probes ensure easy installation even in tight spaces.
• Battery life: four-hour operating time (backup time) per charge on lithium-ion battery.
• Security: safeguard against theft with a Kensington lock.
• All new, Energy Analyze application software: download, analyze and
automated reporting for a complete picture of energy saving potential.
Load studies - Discover how much energy individual
pieces of equipment are consuming when they are operating at minimum and
maximum capacity. Check capacity of circuits prior to adding additional
loads (various standards exist for this process; in the US the NEC
220-87 is the recommended standard). Load studies can also identify
situations where you may be exceeding the allowable load on the circuit
or when an agreed peak demand applies from the utility. For convenience,
some load studies simply measure current which makes installation of
the measuring equipment quick and easy. It is often recommended that
load surveys be performed for 30 days so that all typical load
conditions are encountered during the test.
Energy surveys - Users often ask where measurements
should be taken for an energy survey. The answer is multiple points
within the facility. Start at the main service feeders; compare the
power and energy measured here with the readings from the utility meter
to ensure you’re receiving the correct charges. Then move downstream to
the larger loads; these should be easy to identify by the current rating
of the electrical panels downstream of the service entrances. Measuring
at many points will allow a full picture of energy usage across the
facility to be developed. The next question users typically have is how
long an energy survey should last. This of course depends on the
facility, but it is recommended that you measure for a period that
matches a typical facility activity period. If the facility operates
over a five day work week with down time on the weekend, a seven day
survey will most likely capture typical conditions. If the facility
operates at a constant level for 24 hours a day, 365 days a year, a
single day could be reasonably representative as long as you avoid a
period where there may be planned maintenance. To capture a full picture
of the facilities energy usage it is not necessarily required to have
measurements made simultaneously at every consumption point in the
facility. To get a comprehensive picture, spot measurements can be made
and then compared on a sliding time timescale. For example, you could
compare the service entrance results from a typical Tuesday between 6:00
am and 12:00 pm with those of a larger load in the facility. Typically
there will be some correlation between these profiles.
Simplified load studies - For situations where it’s
either difficult or impractical to make a voltage connection the simple
load study feature allows users to perform a simplified load study by
measuring current only. The user can enter the nominal expected voltage
to create a simulated power study. For accurate power and energy studies
it is required to monitor both voltage and current but this simplified
method is useful in certain circumstances.
Power and energy logging - When a piece of equipment
is operated it instantaneously consumes a specific amount of power in
watts (W) or kilowatts (kW). This power is accumulated over the
operating time and expressed as energy consumed in kilowatt hours (kWh).
Energy is what your electric utility charges for; there will be a
standard charge from the utility per kilowatt hour. Utilities may have
other additional charges, such as peak demand, which is the maximum
power demand over a defined period of time, often 15 or 30 minutes.
There may also be power factor charges, which are based on the effects
of the inductive or capacitive loads in the facility. Optimizing peak
demand and power factor often results in lower monthly electricity
bills. The 1730 Three Phase Electrical Energy logger has the capability
to measure and characterize these effects enabling you to analyze the
results and save money.
