Product:isoPV

Electrical safety in photovoltaic power plants

based on IT system with ISOMETER isoPV and

insulation fault location systems EDS

In photovoltaic power

plants, operation as

far possible without

interruption is a key

objective, as a plant

failure will result in a

direct loss of revenue. This situation means that high

requirements are placed on the electrical safety, and

also especially on the plant protection.

The ISOMETER isoPV is an appropriate insulation

monitoring device suitable for the high DC voltage

up to 1,100 V. Due to wide spatial distribution or

EMC interference suppression methods often high

leakage capacitances (up to 2,000 F) against earth

occur in these systems. Considering this, the isoPV

automatically adapts to the system conditions in order

to optimise the measuring time. In particular, the

requirements for permissible voltage ranges along

with a low level of insulation can be met here. In

addition, this insulation monitoring device can be

combined with an automatic or manual insulation fault

location system EDS. The system is flexible and can

therefore be optimally adapted to the various different

types of photovoltaic power plants.

Product: T-ERA Range of low voltage power

Switchgear & Controlgear assembles

The T-ERA low voltage switchboard symbolizes a

new era in power distribution technology. It offers

complete solution in distribution,

protection, control and monitoring

of electrical power. Winner of the

Best Product award, T-ERA is

L&Ts answer to the challenge of

increasing costs of engineering

and installing low voltage

switchboards and emphasis on

operator safety.

T-ERA is an embodiment of life

protection and equipment safety, security and energy

efficiency. The design and development team of L&Ts

Electrical and Automation business has painstakingly

translated research and critical marketing inputs

into a compact design of switchboard which is the

latest example of innovation in compactness, energy

saving, safety (its features go beyond the prescribed

standards), user convenience and flexibility to

reconfigure the design.

T-ERAs contemporary design features include newbusbar design for high level of energy efficiency and

compact footprint with multiple access and stacking

configurations for optimizing substation layouts. It

caters to simplified communications solutions and

serves as a key building block of the concept of

intelligent switchboard. Another feature of T-ERA is

re-engineering and change management through fully

interchangeable modules. In order to ensure highest

level of safety for the operating personnel as well

as safety and reliability of the installation, T-ERAs

efficiently embedded features comprise all closed

door operations, distinct vertical earth bar over and

above the horizontal earth bar and higher clearance

and arc resistant design.

performance. It

has high number

of poles and

better magneticcircuit with the

rare earth PM disc

Rotor. The rotor

of the motor consists of a rare earth magnet having

the shape of a thin disc which is axially magnetized.

A particular magnetization method allows for a high

number of magnetic poles, giving much smaller step

angles. Such a rotor design has a very low moment

of inertia, resulting in outstanding acceleration and

dynamic behavior.

The magnetic circuit is independent. There is no

coupling between phases to get superior angularresolution in micro stepping.

The motor consist of two stator phases & requires

two control circuits. The controller is based on

microstepping principle. The controller is designed to

the get output current to achieve the microstepping

upto 32 steps in both phases. Stepper Motors are

used wherever incremental motion is needed. It is

used in controlling the velocity, the displacement,

and the moving direction. It finds continued

applications in the controlled motion devices,

medical equipments, printers, computer peripheral

devices and other such motion.

Product:ELTRIX DOPS (Despatch Operations of

Power Systems)

Operational efficiency, competitive pressures,

deregulations and quality customer service

requirements continuously influence the energy and

utility industry. Under such dynamic environment, it

is important for utilities to take critical decisions in

their day to day operations for achieving strategic

objectives. Kalkitech ELTRIX software frameworkprovides a platform, addressing intelligent decision

support requirements in the power system domain.

ELTRIX covers the decision support requirements

within Generation, Transmission and Distribution sub-

domains through a number of domain modules.

Dispatch Operations of

Power System (DOPS)

module of ELTRIX

empowers Independent

System Operators

(ISOs) and the Load

Dispatch centres (LDCs)to perform various

business and operational

functions, monitor and enforce grid code compliance

by constituents, optimally schedule Dispatch

Operations, contingency management, demand

forecasting, energy accounting and billing. DOPS

has the capability to support the operations of various

deregulated and regulated markets by means of

standard information modules, rule & work flow

management, and model based interfaces.

DOPS provide scalability for larger operations and

gives advantage of interoperability through IEC-61970and IEC-61968- CIM (Common Information Model)

and GID (Generic Interface Definition) services for

power systems. Further, DOPS has an engineering

interface development environment where customers

can build and use power & energy system models.

One of the key features of DOPS is Domain Rule

Management. It is used for implementing a regulation,

domain/ business rules and strategy which may

change in due course of time like Availability Based

Tariff (ABT) regulations. One of the key features of
