SCADA-ready Installations
A “Quick Install” switch can be manually operated with a swing handle or
a wormgear type operator, depending upon the type of interrupter supplied
on the switch. The switch may also be operated with a transmission class
motor operator for remotely operating the switch through a customer’s SCADA
system.
A SCADA-ready installation would consist of a “Quick Install” switch,
Cleaveland/Price BT-T motor operator, customer’s choice of RTU, provision for
customer’s choice of communication means, and any other specified equipment
such as sensors or fault indicators.
SCADA installation with
BT-T motor operator and
communication by satellite.
The BT-T operator is a 17,000 in-lb. torque
operator that will open or close a switch in 3.4
seconds with 180° rotation of the vertical
operating pipe. It comes with a padlockable
safety cover that protects operating personnel
from rotating parts and also prevents tampering
with the mechanism. A padlockable torque–relief
decoupler is also provided. The motor operator
is supplied with contacts that will indicate the
true switch position whether the vertical pipe is
coupled or decoupled. For manual operation,
a telescoping swing handle and handcrank are
supplied.
At locations where low voltage AC is not
available for charging the BT-T’s battery, a
complete solar charging package can be offered. Consult the factory for more
information.
