PACiS
A Real Time System
for Automatic Electrical Loop Re-configuration
To ensure the continuity of supply and secure operation of electrical networks in
hospitals and healthcare institutions, it is essential to be able to isolate the faulty
section and safely re-energise the remaining installations.
The fast response of the PACiS solution (<500 ms) goes well beyond the
requirements of national standards and regulations, which typically impose a
response in less than 2 seconds.
The PACiS solution is fully customisable to match all electrical network topologies.
Architecture
The PACiS solution is based on an Ethernet IEC 61850 client-server architecture.
MiCOM C264 real time Programmable Logic Controllers, inter-connected by a redundant fiber-optic network,
manage the electrical network and connected equipments.
MiCOM and Sepam Protection IEDs, Human-Machine Interfaces (HMI), fault detector Easergy T200, and
gateways (GTW) will interface with your Building Management System (BMS) to complete the PACiS solution
and increase the capabilities of your power system.

PACiS
Protection Relays
and Fault Detection
Detection, protection and location of
electrical faults are the key points in any
application.
Immediate and reliable fault detection & location
is ensured through the use of the instantaneous
information from MiCOM and Sepam protection relays
or fault detector Easergy T200 integrated in PACiS.
MiCOM and Sepam relays, in addition to their
protection functions, provide measurement and
all monitoring information required for efficient
maintenance and easy post-fault analysis.
When the short-circuit power of the units does
not allow the MV bay fuses to blow, the
MiCOM P114S relays ensure back-up protection
on the outgoing feeders, thus preventing their
definitive tripping.

PACiS
Components
PACiS solutions are mainly based on
MiCOM C264 devices interconnected via
redundant fiber optical Ethernet
IEC 61850 network.
The MiCOM C264 is a real time PLC dedicated to
the management, supervision and control of EHV,
HV or MV electrical networks. MiCOM C264 is fully
compatible with all IEC and ANSI electrical standards.
Supervision – Simulation PC
PACiS systems can be complemented with one or
several supervision PCs to monitor and control the
network. Simulation and test modes may complement
the solution.
Web Access
MiCOM C264 provides web access, allowing the
display of measurement and logic data using a
standard PC Web navigator.
Gateway
Connection to the site BMS is a native feature of
PACiS systems based on standard communication
protocols: OPC, MODBUS, PROFIBUS.
Alarm
Any alarm or event impacting the site electrical
network can be transferred to an operator 24/7
using GSM call messages, SMS, text or web mail
PACiS MAIN FUNCTIONS
•Supervision of the electrical installation
•Fault location and analysis
•Electrical loop network management
•Transformer load shedding (optional)
•Emergency generator management
•Relay selectivity optimization

PACiS
Applications
The electrical network elements are
managed using PLC IEDs connected
together with the PACiS system.
PACiS manages Integrated Solutions (cubicles or
cabinets with power supply), and Centralised
Solutions (hardwired data or distributed
communication networks).
Standard PACiS system includes:
•5 electrical network management modes:
Normal, Back-up, Maintenance, Inhibited and Test
Mode
•Service restoration, islanding management
and grid reconnection
•Automatic adaptation to topology
•Network power supply switchover:
- to a second delivery substation
- to a second back-up substation
•Capability to use disconnectors instead of circuit
breaker
•Transformer load shedding – Load management
- via secondary substation transformers
- via network disconnectors
•Compatible with any MV earthing method:
Isolated / Direct / Resistance and Petersen Coil
compensated
•Emergency generator and energy storage
management:
- Start and stop
- Voltage and frequency control
