Ayudha Puja is a beautiful Hindu tradition that

dates back to thousands of years. This is also known

as ‘Astra Puja’ and employees worship various

tools, objects and machinery that they use every

day.

Every year, we have a grand Ayudha Puja that

brings together all employees and we celebrate it

with Pomp and Splendour. This is performed to

bring in happiness and prosperity by invoking

God's blessings. The wonderful thing about this is

that builds an inner realisation that work is an

offering to God. This thought is a highly motivating

force that pushes us to do our best and touch a new

summit of excellence.

This year, we celebrated Ayudha Puja on

1st October 2014 at our three manufacturing units

at Hosur in Tamil Nadu and Bangalore in

Karnataka. A grand puja was performed in all the

units and delicious sweets and fruits were

distributed to all employees. Every one went home

with happy hearts and blessings.

ERL’s F-PRO is gaining currency in the power

industry as it incorporates many valuable features

and offers a great deal of flexibility. There is a

good demand for this product and we have

bagged some good orders for it too. It offers

diverse applications like providing current and /

or voltage protection for Lines, Transformers,

Generators, Motors, Busbars, Reactors,

Capacitors and so on. The rear communication

capability such as IEC 61850, IEC 60870-5-103

and Modbus allows integration into a Substation

Automation or Monitoring System / SCADA.

F-PRO is a family of Multi-function Numerical

Relays that complement each other. Each relay in

the family has its own set of functions which can

meet many kinds of power automation

applications. The products in the family are

configured with a set of current and / or voltage

operated protection, metering and data

communication functions.

System analysis is a crucial part of the role these

products play and they can generate fault logs,

disturbance recording and sequence of events

with 1ms time stamp resolution. The relay is draw

out in construction and this enhances

serviceability and ease maintenance.

Key Functions of F-PRO Relays:

F-PRO series of relays offer various current and / or

voltage protections packaged into simple to use

configurations.

ERL Mint impresses Kenya

Substation Automation System (SAS) and

commissioned the Control Relay Panels at

Neyer i Sub S ta t ion ,Kenya. ERL had to

integrate two other supplier's equipment (ABB

and CGL) as part of the SAS too and we had

been quite successful.

KPLC was very happy and appreciative about

the performance of ERL in getting the SAS up

and running. This encouraged the uti l i ty

(KPLC) to award ERL Mint a new order through

Etrade. This was for 66kV Substation panels

with SAS located at Lokhichar.

The new order includes supply of 66kV CRP,

S A S , t r a i n i n g f o r C R P & S A S a n d

commissioning of our system at site.

Eight more packages are tendered by KPLC

and we are confident that ERL Mint will bag

more orders soon.

We congratulate the entire team for their

effort.

ERL handles a challenging project in Ghana!

It has indeed been a sweet victory for ERL at Ghana.

Despite facing different hurdles, our team

successfully commissioned a 161/34.5kV

Substation in Kumasi, about 300 kms from Accra, a

Ghana SAS System (with IEC 61850 Protocol).

ERL engineers did their work efficiently and

completed the commissioning of the subject S/S.

The project had been awarded to KEC who in turn

offloaded the Protection and Automation part to ERL

Marketing International (ERL Mint). The result was

that to complete this project our engineers had to

rectify many problems in the Switchyard which was

beyond ERL's purview. We are proud that we went

that extra mile to keep our client happy.

Some of the key highlights are:

• Multi-vendor Product Integration with the

Automation system.

• Complete S/S controlled from the Remote Control

Center through ERL Gateway installed in the .S/S

• Midway into the commissioning, we were asked

to integrate two 34.5KV Capacitor Bank

protection into the SAS which was done at site,

in a record time of 2 days! (Including Engg.

& Integration).

We congratulate our team on their exemplary

work.

in Kenya to integrate Multi-vendor Protection

Products (ERL’s PRO relays, ABB relays, Sprecher

(Austria) BCU & Gateway into the new Sprecher

Automation system with IEC 61850 protocol.

We are also the first in Kenya to attempt and

successfully commission Dual Hot Standby

Redundant Gateway System. This hi-tech system

was successfully implemented by ERL Engineering

& Commissioning team .

The Contract for Engineering, Manufacturing and

Commissioning the SAS system with the protection

package was awarded to our ERL Marketing

International (ERL Mint) who in turn sub-contracted

ERL to Engineer, Manufacture and Commission.

The combined team work of tender ing,

engineering, manufacturing and T & C ensured the

smooth progress and completion.

We congratulate the team on their accomplishment.

Computers have electronic clocks very much like the modern watches we wear on our wrist. They

have small batteries that continue to run the clock when the power is off. Ordinary button batteries

we use in our watches would do, but small rechargeable batteries are also possible.
