TESLA LITEis an economical user-friendly multi-timeframe power system recorder that provides multifunctional recording and event logging with advanced communications. This easy to use multi-time frame recording system records 12AC currents, 6 voltage channels and 38 digital (status) channels and stores 250 recordings in on board memory.
The TESLA LITE records data simultaneously in three time domains: High speed transient fault (seconds), Low speed dynamic swing (minutes)and continuous trend (10 Second to 1 hour intervals). a wide variety of triggers are available to initiate recording
The intuitive TESLA control panel user interface software configures the recorder, retrieves and manages records and displays real time measured values. Control Panel also includes Record graph, a graphical record display and analysis software tool.
These features make TESLA LITE a cost effective independent and complete recording solution for small substations.

Application

• Complete power system recording for custom applications in smaller substations
• User- Configurable trend recording
• Data compression for fast file transfer.

TESLA 4000is an intelligent, state of the art, user-friendly multi-timeframe dynamic power system recorder with advanced Phasor Measurement Unit (PMU) and Continuous Disturbance Recording (CDR) capabilities.
TESLA 4000 is an easy-to-use and cost effective, state of the art, multi-time frame (simultaneous) power system monitoring recorder. The integrated Phasor Measurement Unit (PMU) functionality streams synchrophasor data for wide area monitoring.
The TESLA creates records simultaneously in three time domains - fault (fast), dynamic swing (slow) and trend records and also creates event logs.
The CDR creates continuous records without triggers which together with the fault, swing and trend records provides wide area visibility of system performance. The CDR also creates redundancy in PMU data.With these powerful recording and communication capabilities, the TESLA recording systems provides the most versatile and complete monitoring of power system health.

iCBseries comprises embedded pole type vacuum circuit breakers for medium voltage and indoor use. They are suitable for three phase AC operations for 12kV, 17.5kV, 24kV and 36kV and are used for the protection of the electrical equipment in various industries, mining, and especially for medium voltage distribution sub stations, together with suitable air-insulated cubicles.
The iCB used German Technology and is available in complete series for medium voltage and for all commonly used rated currents, from 630A to 4000A, and for rated breaking current up to 40kA.

Application

• Suitable for 3-phase AC operations for 12kV, 17.5kV, 24kV and 36kV
• Medium voltage distribution sub stations

ERL in technical collaboration with Joslyn Clark, U.S.A offer a range of rugged Medium Voltage Vacuum Contactors for heavy industrial applications. Unlike conventional devices, these vacuum contactors enclose the power contacts within a vacuum chamber.

APPLICATIONS

• MV Motor Starter & Control
• Transformer & Capacitor Switching
• Pumping
• Induction Heating
• Soft Starters
• Transfer Switches
• Hazardous area equipment
• Crane Control
• Conveyors

The relay is suitable up to four shots. It consists of four cards viz.front fascia, power supply status input & output card and Micro controller card are housed in a compact 3N Non draw-out case.
Micro controller does the sequence control and timing function. The DIP Switches on the relay front fascia select different operating functions and time setting.There is a watchdog timer in the relay which continuously monitors the program, put off ^POWER ON^ LED indication if the watch dog timer elapses.
To start an auto re close cycle, the initiating contact from the protective relay must be closed without chatter for at least 12 milliseconds.

Inputs:Two optically isolated inputs are provided. One is used to take the three phase protection operated contact inputs to initiate the auto rec lose relay.
The another input is used to block the re close functions if the external blocking input is initiated.

Reclose Timer:The relay has four re-close timers. The relay selects the respective timer sequentially depending upon the number of re-close selection and the re-close initiation.

Reclaim Timer:There is the common reclaim timer. It operates in series with the re-close timers. The over all reclaim time delay from the relay initiation to relay reset is therefore reclaim timer setting plus re-close time. For every initiation the reclaim time counting are resets automatically.

Lockout Function:When the number of shots switch is in OFF mode the protection operated contact input initiation condition it will energize the lockout relay and lockout LED indication and it blocks the re-close function.
When the external blocking input is initiated, the re-close function is blocked and it energize external blocking LED, Lockout LED and Lockout relay.
As the relay allows the maximum of four re-close depending upon the number of shots selection, the number of shots is less than the number of initiation within the reclaim time it will energize the lockout relay and its LED indication
