Description
The Ekip Measuring is an accessory module for measurement of voltage, power and energy.
Specifically:
• It measures the RMS value and frequency of the voltages of the three-phase system on the
internal contacts of the circuit-breaker, or on the external sockets. From these measurements,
the release obtains those of the power and energy, which therefore become available.
• Combined with the Ekip Synchrocheck module, it makes it possible to recognise whether
the synchronism conditions exist between the internal contacts (or external sockets) and
external contacts necessary for closing the circuit-breaker.
There are two possible types:
• Ekip Measuring, that includes only the measurement function (see the chapter "15 -
Measuring Measurements, on page 130).
• Ekip Measuring Pro, with a measurement function, the possibility of powering the release, and
activation of the Measuring protections (see the chapter "10 - Measuring Pro protections”,
on page 96).
With the Ekip Measuring Pro module, the power supply of the release is guaranteed, if at least
one phase-to-phase voltage is greater than or equal to 80 V AC.
Compatibility and power supply
The Ekip Measuring and the Ekip Measuring Pro module can be installed with an Ekip Touch
release, the former if you only wish to implement the measurement function and the latter if you
also wish to implemented the power supply function and activate the Measuring protections
With Ekip Hi-Touch, G Touch, and G Hi-Touch releases, Ekip Measuring Pro is provided as
standard.
The Ekip Measuring module requires the release to be powered with an auxiliary voltage (for
example, supplied by an Ekip Supply module). The auxiliary power supply is not necessary with
Ekip Measuring Pro.
