The RE-2VAD is used to measure and record the amount of energy being imported (from the grid) and/or exported (to the grid) by a building with renewable energy source(s). The RE-2VAD can detect the direction of flow of energy into or out of the building and therefore determine when you are generating or consuming energy.

The advantage of the Electrocorder products over most others is that our data loggers constantly sample information (recording the Min, Max and Average)over the set period, many other products only take 'snap shots' of what isgoing on and can miss 99.9% of the data that is critical to your analysis.

Kit includes data logger, voltage input lead, one clamp-on CT, USB lead, Electrosoft software and a carry case.

Q1. What is the Electrocorder?

A. Electrocorders are a range of voltage and current loggers.They allow users to monitor and record voltages and currents in electrical systems, the products record the average voltage or current, maximum voltage or current, & minimum voltage or current, with dates and times.The loggers store this data to internal memory for later analysis using Electrosoft, the supplied Windows based software. The Electrocorder allows users to quickly and cost effectively monitor supplies.

Q2. Why is the Electrocorder different?

A. The Electrocorder range use a constant sampling technique, unlike the single reading of competitors. When the loggers start to record, they sample every channel 16 times per cycle, a cycle is 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. This means that it will record all the peaks and troughs which are one cycle or longer.

Q3. How does it work?

A. The Electrocorder samples the voltage or current input 16 or 32 times per cycle (model dependent), it then averages each voltage cycle over the selected period (1 sec to 60 min). A cycle is 20ms for 50Hz or 16.6ms for 60Hz. Throughout each averaging period, it monitors and records the lowest & highest voltage (and/or current) cycle values and stores the data along with date and time in memory. For example, on a single channel voltage logger (EC-1V-IP65):- You want to record voltage over a period of 1 week - you set the Electrocorder EC-1V to have an averaging period of 2 minutes, which actually gives 10 days of logging.The Electrocorder will sample every voltage cycle. During each 2 minute period it calculates a running total. At the end of the period the True rms voltage over that preceding 2 minute period is calculated and saved. Also during the preceding 2 minute period it will have recorded the single lowest voltage cycle value and the single highest voltage value. For example, at the start of the 2 minute period the Electrocorder will start sampling every voltage cycle. It looks at each cycle value and compares each to the lowest and highest it has seen to this point during this 2 minute period, if the value is lower (90V) than the previous lowest (101V) then it will replace the value in the‘min voltage’ location. Similarly if it is higher (230V) than the previous highest (222V), it will replace the value in the ‘max The Electrocorder will not identify the exact time of the max or min, except that it occurred during this 2 minute period, which does have a date and time! It will record and calculate the average (RMS) voltage or current over successive 2 minute periods, along with the date and time. So, for each 2 minute period, 3 values will be recorded, (1) Average Voltage (230V), the average of every cycle during the 2 minute period, (2) Minimum Voltage (209V), the lowest cycle voltage and (3) Maximum Voltage (241V), the highest cycle voltage.

Q4. Can it detect spikes?

A. YES, it will see events of 1 cycle (16/20ms, 60/50Hz) or longer. It will record a single minimum and a single maximum voltage cycle (16/20ms) during each averaging period. If the averaging period were set to 10 seconds, the Electrocorder would sample every cycle 32 times and at the end of each 10 second period, calculate an RMS average,also during the 10 second period it would record the lowest and highest cycle value. Domestic customers do not normally see events less than one cycle!

Q5. Does it measure true RMS voltage?

A. YES, it samples every voltage cycle 32 times and calculates the RMS value at the end of each averaging period. It can be set to measure to EN 50160:1994 (10 minute rolling average).

Q6. Does it measure and conform to recording standard EN 50160:1994?
(“Voltage characteristics of electricity supplied by public distribution systems”).


Q7. What Category (CAT) is the Electrocorder?

A. Model dependent, please see the relevant datasheet.

Q8. Can the software be run on Linuxor a MAC?

A. No, only PC Windows based at present, however we are developing Electrosoft to run on these other ‘platforms’.

Q9. Is the Electrocorder available with other memory sizes?

A. Yes, the basic models have 64 kilobytes per channel of non-volatile SEEPROM, we may be able to supply double memory per channel, please contact your local distributor or Acksen Ltd.

Q10. How accurate is the Electrocorder?

A. Within the range 90 to 260 Vac accuracy is ±1% of reading.
