Ensuring power availability
at any time
Medium Voltage Distibution
RM6 Automatic Transfer System (ATS)
Automatic Transfer System
Because a MV Power Supply interruption
is unacceptable especially in critical
applications, an automatic system is
required for MV source transfer.
For your peace of mind, RM6 enables
automatic control and management
of power sources in your medium
voltage secondary distribution network
with a short transfer time (less than 10
seconds), guaranteeing
the hi-reliability of your installation.

On loss of voltage on L1, the Automatic
Transfer System automatically switches
to L2.

On loss of voltage on line, the ATS starts
genset and switches to genset.
On loss of voltage on one line,
the ATS opens this line and closes
the bus coupler.

Caracteristics
• Boost operating efficiency with automatic monitoring and
guaranteed power availability — ATS comes with an optional
communication module to transmit information to a remote
control system.
• Automatic control is performed by Easergy T200 I
This T200 I device can also be used for remote control with a
wide range of modems and protocols.
• Automatic Transfer System (ATS) to switch the MV
connection to back-up generator can reduce your
operational expenses
Tariff optimisation: you can negotiate a better rate with your
Electrical Utility if you accept to disconnect from network during
peak hours. The Utility sends a signal just before the higher
peak rate. ATS receives this signal and:
- Starts the generator
- Turns on the main switch once the generator is ready
- Turns off the generator switch
• Forcing ATS with generator
- From a remote control
- From a digital input
Applications:
- maintenance (periodic test of the Genset)
- tariff optimisation
• Factory tested, preconfiguration design
ATS comes ready to install on an RM6 switchboard in a T200 I
box automation comes pre-programmed, eliminating sequence
errors during set up.
• More efficient procurement
easy-to-order based on existing part numbers
• Quick, easy installation
- Plug-in connection only
- Kit included for mounting T200 I on wall or RM6
• Simple commissioning
easy to configure service voltage, time delays, and ATS
operating modes.
• Maintenance free
automatic testing and troubleshooting.

How does it work?
By combining the RM6 switchboard and Easergy T200, you benefit from a hi-reliable
and pre-tested solution that ensures the availability of your energy.

Voltage sensors. Dedicated version of VPIS
with voltage output signal.
2
Voltage detector. A relay is activated when
a loss of voltage is detected from the VPIS
voltage output signal.
Current sensors for Fault Passage Indicator. Should
a fault current be detected, the Automatic Transfer is
locked in order to avoid to close the healthy line on the
fault.
4
Automatic Transfer Smart Device. From the digital
input coming from the VD23, and the FPI information,
this device takes the decision to switch from one line to
the other.
It provides the uninterrupted energy for the operation.
