3.4 Measuring
Various instantaneous measurements are available for each relay, regardless of the functional
characteristics and versions.
Commands for resetting the energy meters and for the measuring history are also available for
certain relays.
The reading of a nil or unavailable current (because it is too low) is indicated by: “...”. When there
are phase errors, the current is indicated by: “---”.
Power measurements (Active, Reactive and Apparent) are available for both single channels and
the whole (e.g.: P1, P2, P3, Pt). If the Neutral voltage is absent, the only measurement available is
the total (e.g.: Pt).
Ig current is only available with the LSIG version of the relays. For the other versions, if
indicated, it is represented by: “---”.
