GENERATOR PROTECTION UPGRADE

How would you like to REPLACE 10 or more of your protective relays with ONE digital relay and also reduce the cost of having them calibrated every 3 years???

Let E-Squared help you get from here:

To Here:

has design & field engineering experience at applying Generator Relay Protection Modules (Beckwith Electric Co. / Basler Electric Co. / General Electric Co. / Schweitzer Engineering) to replace a minimally protected system utilizing the old, existing electro-mechanical type generator protection relays such as the following:

21   Distance Relay               46    Current Negative Sequence Relay

24   Volts Per Hertz Relay    47    Voltage Phase Sequence Relay

25   Synch Check Relay       51V  OC Relay with Voltage Restraint

25A Auto Synch Relay         59    Overvoltage Relay

27   Undervoltage Relay       64G  Generator Ground Relay

32   Reverse Power Relay   81    Over/Under Frequency Relay

40   Loss of Excitation          87G Current Differential Relay

       Relay

offers "Technical Direction / Design Interface" or "Turnkey Installation" Packages with regard to Generator Protection System Upgrades.

Project Tasks can include:

• Site Demolition Activities

• System Fault Studies

• Relay Protection Module Settings

• Auto Synch Module Settings

• Design Interface

• System Drawings (Elementary, Connection & Interconnection)

• Site Installation Activities

• Relay Protection Module Testing & Calibration Checks

• Communication Interface

• System "Trip" Testing

• System Off-Line Synch Phasing Tests

• System On-Line CT/PT Signal Input Phasing Checks

Advantages to applying and installing these new Generator Relay Protection Modules:

• Better System Protection Flexibility

• More Independent Functions Available

• Small Packaging for panel or rack mount

• LCD Displays with real time metering and system monitoring

• Communication Ports for metering, alarms and fault data monitoring from remote locations

• Project Cost Saver (yearly maintenance and calibration testing time is greatly reduced)

• Replacement Costs (costs for an electro-mechanical "40" Loss of Excitation Relay is greater than one Protection Module)
