Energy Audit Kit Identifies Savings Areas and Verifies Performance

Everything You Need for Energy Audits in One Low-Cost Kit!

CHESTERLAND OH – ISO 50002:2014 is a new International Standard providing useful information on energy audits for all types of facilities and organizations. To cut high energy costs, businesses and organizations are installing energy management systems and performing energy audits to reduce energy consumption and improve performance over the long term. For affordable energy auditing and verification CAS DataLoggers offers the EC-7VAR Three-phase Power & Energy Datalogger Kit, which includes the datalogger, voltage leads, transducers, Rogowski coils, carry case, software and a USB lead for quick connectivity. Recording at high speed onto a large memory, this kit has everything you need to get started. Users can view onsite power consumption given in kilowatt hours as a result of logging so that:

If you’re an HVAC installer or electrical contractor, you have proof of power consumption for your clients that your systems are performing as promised.

If you’re a facilities manager, you’ll have the detailed data you need to prioritize and reduce your site’s energy usage. You can also compare results across similar sites and identify supply and equipment issues.

Power and Energy Data Logger

Electrocorder three-phase power factor data loggers record energy (kWh) and power (kW) usage, checking voltage and current variations to diagnose any related issues or to gather data. Since the datalogger records both voltage and current, users can determine if low voltage is related to high current demands onsite or if the low voltage is being supplied to the site.

The EC-7VAR data logger is designed to monitor one, two or three current channels (measuring up to 400A, 1kA, 2kA or 3kAac), as well as one, two or three voltage channels (measuring from 30V-500Vac). The datalogger allows users to monitor the loading and energy consumption of the installation. Power Factor recorded is the phase angle between L1 and A1. When only a single phase voltage supply is available, users can set the EC-7VAR to monitor and record three-phase energy using its three current inputs and a single-phase voltage input instead of the normal three voltage inputs.

At single-phase, the logger records at a range of 30V-300V. For protection from dust and splashes, this durable logger is rated at IP43 and is also available in IP65 and NEMA 12/4 versions. The data logger stores voltage and current levels along with dates and times. With the back-up battery, the device can continue to record for months.

Accessories Included

With Electrocorder kits you save the significant extra cost of current clamps and memory. CAS DataLoggers provides the EC-7VAR as part of a cost-effective kit which includes the datalogger itself, 4 voltage leads, transducers, 3 Rogowski coils, a USB lead for quick data retrieval, and a convenient carry case. The included Rogowski coils fit around 140mm diameter cables and break open at the black joints so users can place them around the cables without needing to break the main circuit.

The included Electrosoft software allows users to define the voltage to plot power and energy, then upload recorded data via USB to a PC for analysis. Using the software users can also print out an audit output graph giving proof of the details of the facility’s energy usage and performance so owners can identify savings areas.

Electrocorder—Superior Sampling

Many competing products just take a single ‘snapshot’ sample and go back to sleep, missing nearly all of the data necessary to find savings and spot problems. By contrast, Electrocorder utilizes a constant data sampling technique which samples every channel 16 times per cycle, a cycle being 16ms at 60Hz and 20ms at 50Hz.

At the end of each averaging period, 3 quantities are saved for each channel: the True RMS average, the Max, which is the highest cycle value during the period, and the Min, lowest cycle value. Electrocorder will record all the peaks and troughs which are one cycle or longer, capturing much more data and enabling truly comprehensive metering.
