Three Phase Current / Load Logger EC-3A
![]() |
Used to determine feeder loading and mainly used by power distribution companies, heavy industry, facilities management, electrical or site services and maintenance engineers to monitor loading variations on site helping them to diagnose any related issues, transformer and feeder sizing problems. Perfect for gathering data to make a case for splitting-up the loading or increasing circuit capacity.
EC-3A-FK, ~4A to 400A (90kVA per phase, 270kVA total)
EC-3A-1K,
~10A to 1kA (230kVA per phase, 690kVA total)
EC-3A-2K,
~15A to 2kA (460kVA
per phase, 1.4MVA total)
EC-3A-3K,
~20A to 3kA (690kVA per phase, 2MVA total)
with models up to 5kA or 10kA maximum input per phase.
All Electrocorders use a constant sampling technique, meaning they sample every cycle multiple times, missing very little data! Many, many other brands do not, they simply sleep for 99.99% of the time, waken to take a sample, then sleep; they miss 99.99% of the data! How can you perform a load survey when 99.99% of the load data is missing?
The EC-3A-xK (Rogowski) models are
designed for large loads, 400A, 1kA, 2kA or 3kA, if you require higher inputs,
5kA or 10kA, please
let us know.
The Rogowski Coils fit around cables of 140mm diameter or less.
Note, the Rogowski Coils break open at the black joint, allowing them to be
placed around the cables without having to break the main circuit.
For current ranges between 5A to 400A we recommend the use of the EC-3A-FK model.
The EC-3A-xK uses USB communications. For lower currents
between 3A and 300A we recommend the EC-3CT
which uses
traditional clamp-on current transformers (CT's) and has a maximum
input of 300A per channel, making it accurate at lower currents,
suitable for domestic and light commercial logging.
EC-3A-xK-IP65-**-KIT includes logger (1), Rogowski Coils (3), USB
lead (1), software (1) and carry case (1).
