ATS Automatic Transfer Switch System

ATS control module

Automatic Transfer Switch Control Module. The module features 8-Bit microprocessor
control. The module is used to monitor two 3-phase AC supply. Once I# AC supply
failure is detected (under voltage,over voltage,miss phase), The module Automatically
transfer the switch to II# AC supply, and control generator to start.

ATS Switch

Single coil & double shafts driver Two switch positions 40-200A, Three switch positions 250-4000A.50,000 electric
switch times, 250,000 mechanical switch times.Used for resistance load 40-200A, inductance load 250-4000A.

IC-NT Synchronizing controller

● Essential load is fed by two mains feeders during normal
operation to achieve maximum reliability of the power
delivery. Bus-tie breaker (BTB) is closed.
● Complex switching algorithm running in external PLC defines
which breakers are opened and which are closed
independent on availability of two mains and gen-sets.
● Reverse synchronizing on both feeders and on bus-tie
breaker is accomplished by 5 InteliMainsNT modules
controlled by external PLC.
● Active and reactive load-sharing can operate in two modes:
⚶ Sharing the load between all running gen-sets ⚶ if BTB is closed
⚶ Sharing the load in two independent groups ⚶ if BTB is opened
● Automatic power dependant start/stop can operate in two modes as well:
⚶ Running on all gen-sets ⚶ if BTB is closed
⚶ Running in two independent groups ⚶ if BTB is opened
● All controllers are interconnected by one CAN bus all the time, disregarded if BTB is closed or open, no
need for relays reconnecting the CAN bus.
● Complete system is remotely controlled and supervised from Control room connected via company LAN
and IG-IB to all controllers.
