1965:

Firstto design and manufacture single phasing preventors in India and fulfill an emerging market requirementinnovatively.

SHAPING THE MARKETMinilec's bench-mark developments have shaped the markets since 1965.For instance, in the year 2002, responding to

customer feedback, we introduced multiple options in enclosures of relays, ( in addition to the existing D1-D2 ), P1-P2

and F3 enclosures. This product enhancement gave our customers the much needed flexibility in terms of size and

started a trend. Another interesting product development came anticipating a market need, the MBAS 9400 with front

replaceable windows, which gave us the edge to win a major tender from Indonesian Electricity Authority against

American and Japanese competitors in 1994. This updation in MBAS 9400 has also ensured a continuous flow of

orders from the Malaysian Electricity Authority since 1994.

BENCHMARK DEVELOPMENTS 1965-2007

1982:

First to launch micro-processor based alarm annunciator.(Redesigned as Microwarn 9000 in 1990), this was, and remains the most beautiful alarm annunciator attracting customers across theglobe.

1984:

First to introduce super bright LEDs for facia of alarm annunciators.

1994:First company in our segment to get ISO 9001.

1997:

First company to introduce RS232 communication port to alarm annunciators.

2000:

Millennium Series (P1 & P2 enclosures)products launched

2005:

MBAS 9700 expanded up to 128 channels.

2006:Microcontroller based relaysreplacing existing relays (D1 & D2 series) introduced.

2007:

S2 (Sleek) Series products with microcontroller & SMD technologylaunched.This technology has the powerful advantage of added intelligence. State of art SMD technology & microprocessor based designgives higher reliability, multi purpose functionality, reduced size & more value.

2007-08:

Innovative and upgraded new products with latest technology arepoised to change the face of the emerging market in India and abroad.

1987:

First to launch prodless dry run protection device pump guard.This innovation alone, won usseveral new customers globally.

Introduction & Application

CORE BALANCE CURRENT TRANSFORMERS (CBCT) is a sensor to

sense ear th fault current in conjunction with an EARTH FAULT RELAY

to protect the system when an EARTH FAULT occurs on one or more

phases. The CBCT is mounted externally & load carrying conductors

are passed through CBCT. The CBCT inner diameter is large enough

to pass all the three bus-bars or the three phase cables, unlike ametering CT where only one bus-bar or cable passes through the CT.

As the VECTOR SUM of the three currents at any given time is ZERO,

the resultant magnetic field through the core of the CT is zero. This is

the healthy situation of the system. If required Neutral also can be

passed through CBCT in case of 3 phases, 4 wire system. Ideally

Vector Sum will remain zero in case of fault free systems.

In the event of an Earth Fault occurring in any of the phases, the

current in that phase rises, inducing a resultant magnetic flux in the

CT secondary, energizing the relay & tripping the system.

The current at CBCT secondary will depend on the actual earth fault

current level & hence unbalanced loading does not affect the

functioning of Earth fault relay.

Salient Features

These relays are useful for protection of 3-phase AC

induction motors against various hazards. Withtheir unique advantages they eliminate use of athermal/bimetal relay for motor protection. Beingcurrent sensing, they are to be selected according tomotor rating and are available for practically allranges of motors. These relays are ideally suitablefor Air-conditioning Compressor motor protection,as also for motors in machines, conveyors,cranes/hoists and lifts, and for pumps.

The input Voltage and current signals arescaled down through interposing andcurrent transformers. The scaled downvoltage signal proportional to vcos. Thissignal is divided by the voltage signal to getDC Voltage linearly proportional to PowerFactor. This output is further processed toprovide DC Voltage / Current output signal.

The Transducer is suitable for balancedoad conditions only, when used on 3Phase 3 Wire, 3 Phase 4 Wire electrical

networks.

The input Voltage and current signals are scaled down through interposing potential and current transformer.In case of reactive transducers the voltage signals are 900 phase shifted. The scaled down signals are fed toprecision multipliers working on time division multiplication principle. The multiplier output is processed toprovide DC Voltage / Current output signal proportional to input active / reactive power. For Signal Phasenetwork, only Active Power Transducer is offered. Fro 3 Phase 3 Wire or 3 Phase 4 Wire electrical networksboth Active and Reactive Power Transducers are offered for balanced as well as unbalanced load conditions.

The input signal is filtered and processed to convert into a standard dc voltage. This voltage is fed to a linear optocoupler which

provides the required galvanic isolation. An optical feedback is used for improved linearity, response time and temperature effects.

The output from the linear optocoupler is fur ther processed to provide dc voltage / current output.

The isolator with fast response time (10 mSec) are typically used in feedback control system.

In input dc current is chopped by the chopper to convert it into high frequency ac signal. This signal is fed to an isolating high

frequency transformer. The ac output current from the transformer is rectified and filtered to obtain load independent dc output

current. As the transformation ratio is 1:1 the output current is identical in value to the dc input current.

D3 TTT1Transformer Tap Position Transducer

D3 RET1Resistance Transducer

It is a precision grade transducer is used for galvanically isolated measurement of Transformed Tap or Resistance (2 Wire or 3 Wire). It measures the value of

resistance on tap position changers, typically used on high voltage transformers. Each position on the selector has an equal value of resistance so that as the tap

position is increased or decreased the value of resistance increases or decrease respectively. The input is in the form of Resistance and provides a Stable, Ripple-

Free and Optically Isolated DC load independent output in the form of current or voltage. The transducer is fully solid state. Use of latest circuit techniques and quality

components ensure reliable operation over long period.
