DATAKOM DKG-117

Description

DATAKOM DKG-117 is a Synchroscope and Check Synchronization Relay designed for synchronizing generators with other generators or the main grid. It provides visual indications and relay outputs to ensure proper synchronization, allowing generators to be connected safely and efficiently.

Features:

Synchroscope Function:

• Indicates the phase difference between the generator and the busbar (mains or another generator).
• Provides a rotating LED pattern to display the phase relationship:

1. 1. 1. Clockwise rotation: Generator frequency is higher than the busbar.
      2. Counter-clockwise rotation: Generator frequency is lower than the busbar.
      3. Static position (12 o’clock): Generator and busbar are in phase.

Check Synchronization Relay:

• Automatically determines when conditions for safe synchronization are met:

1. 1. 1. Phase angle difference is within the set limit.
      2. Voltage difference is within the set limit.
      3. Frequency difference is within the set limit.

• Activates a relay output to close the circuit breaker.

LED Indicators:

• Visual indicators for:

1. 1. 1. Frequency difference.
      2. Voltage difference.
      3. Phase angle alignment.

Adjustable Parameters:

• Configurable limits for:

1. 1. 1. Voltage difference (e.g., ±10%).
      2. Frequency difference (e.g., ±0.2 Hz).
      3. Phase angle difference (e.g., ±10°).

Compact Design:

• Panel-mounted unit with a clear and intuitive display.

Wide Compatibility:

• Suitable for synchronizing generators of various capacities and types.
