ALIBERT + Serge VOLUT

Key points justifying the Schneider Electrics interestWe are making business with this range of products, we need to control the

associated requirements.

Policy of the topic

Raise the bar slowly / carefully.To encourage convergence for a unique world-wide standard

Standardisation requirements just meeting customers need.

In Europe, to publish 60255-26 and 27 as Harmonised standards in the

frame of EMCD and LVD, consistent with IEEE standards on the longterm, accepted in China

The objective is to avoid testing over costs due to :

Either, any local or specific requirement

Or, any interpretation in testing procedure.

To minimize the influence of main competitors prescriptionDevelop standards defining the protection functions for protection relays ,

Close the gap from our competitors about IEC 61850:

Be part of standardization in TC57

Develop products and take care of system approachmonitor the work related to "security" (against hackers, ...), it mightbecome an important topic.

Promote Functional safety approach for special markets (IEC 61508)

Develop Power Quality functions in our products (IEC 61000-4-30)

LPCT, LPVT: standardize those sensor in order to let customers acceptthem

SWOTSWOT

Threats :

Security: Impact of activitiesin the security field inTC57 ?

Impact of Merging Units(current and voltage should

be sent as digital values on abus, with a synchronisation)

Opportunities :

A new range of IMD underdevelopment in PMC.

Strength :

=S= has got secretaryof TC95

Weaknesses :

We are not present in HighVoltage protection, then

we are blind.We are only worldwide

N8.

We are late on IEC 61850
