1. Ashida Electronics

2. Protection Relay
• Protection Relays is an electrical device designed to
make to get protect during any electrical damages.
• Protection Relays is a smart device that receice the
inputs, make it compare according to set of point and
finally provide outputs. Input can be electrical voltage,
current, temperature and provide output in the forum of
visual feedback like indicator lights, alert alarm etc.

4. Protection Relay
• Protection relays is become necessary of every
plant & factory to make protect from the
electrical damage.
•There is available types of protection relays,
which is used according to electrical equipment
requirement.

5. Types of Protection Relay

•Control and Relay Panel

6. Self Powered Relay
• Self powered relay is
design for over current
protection function with
three independent states
(I>1, I>2 & I>3). It also
provide addition function
to prevent damages to
the power system

7. Feeder Protection
• Feeder protection relay is
provides integrated
protection, monitoring &
controlling function for over
head transmission, wires,
cable line, distributes
feeder, underground cable.

8. Transformer Protection
• Transformer protection
is design & develop for
various transformer
applications, providing
state-of-the-art
protection and control
function to power
system.

9. Motor Protection
• Motor protection relay
is provides integrated
Protection, Control and
Monitoring functions for
Electric Motor. Also
availabe in three versions
– basic, extended &
modular version.

10. Line Protection Relay
• Line protection relay is
applied for protection,
control & monitoring of
line radial and ring main
feeder to achieve
sensitivity and selectivity
on phase and ground
faults.

design & develop perfect
SCADA ( Supervisory
control & data system)
especially for substation
automation, It powerful
SCADA power help to bring
whole substation control at
your fingertip.

12. Auxiliary Relays
• An auxiliary relay is a
relay that assists another
relay or device in
performing an action. It
does this when its
operating circuit is opened
or closed.
