Description

KRIES CAPDIS-S2 Capacitive Voltage Detection System

Product Dimensions：

The Kries CAPDIS-S2 (and the enhanced CAPDIS-S2+) is a sophisticated Integrated Voltage Detecting System (VDS) designed for high and medium-voltage switchgear. It provides continuous three-phase voltage monitoring and is used to confirm the absence of voltage safely, according to international standards like IEC 61243-5 and IEC 62271-213.

Below is the detailed product information in English.

1. Product Description

The CAPDIS-S2 series consists of maintenance-free voltage detectors that do not require an external battery for their primary function. While the CAPDIS-S1 is a basic indicator, the S2 version includes integrated relay contacts for remote signaling and control functions, making it suitable for interlocking and automation within smart grid environments.

3. Key Advantages

• Maintenance-Free: Permanent self-monitoring and “Fail-Safe” design eliminate the need for periodic manual testing.

• No Battery Required: Voltage detection and self-testing functions work without external power or batteries.

• Integrated Self-Test: Features a built-in test button to verify the functionality of the display and electronic circuits.

• Smart Grid Ready: Includes interfaces (Y-interface) for connecting to direction-sensing relays (e.g., IKI-50) and monitoring systems.

• Inherent Safety: Provides “Broken Lead Detection” (optional/switchable) to distinguish between actual voltage absence and a cable fault.

• Insulation Monitoring: Continuously monitors the health of the capacitive divider.

4. Product Applications

• Medium and High-Voltage Switchgears: Used as a primary safety device to check for voltage absence before maintenance.

• Remote Monitoring: The relay outputs allow integration into SCADA systems for real-time status updates.

• Interlocking Systems: Used to prevent accidental grounding or switching operations when voltage is still present.

• Partial Discharge (PD) Detection: Newer R5 versions include PD detection to provide early warning of insulation degradation.

5. Precautions & Important Notes

• Configuration: During ordering, the rated operating voltage ($U_n$) and the coupling capacitance ($C_1$) of the insulators must be specified to ensure the device is correctly calibrated.

• Auxiliary Power: While the visual indication works without power, the relay outputs and status LEDs require the auxiliary supply (24-230V AC/DC) to function.

• Phase Comparison: Only use the integrated 3-phase test point (LRM interface) with compatible testers (like CAP-Phase) for phase sequence or comparison tests.

• Installation: Ensure the device is mounted in a dry, dust-free environment or within a housing that meets the required IP rating for the specific site.
