Product Description

The CAPDIS-S2 is a maintenance-free voltage detector that complies with IEC 61243-5 and IEC 62271-213. Unlike basic indicators, the S2 version features integrated signaling relays, allowing the voltage state to be integrated into control systems or interlocking logic.

• Technology: Capacitive voltage detection.

• Versions: * CAPDIS-S2+: For medium voltage (1–52 kV).

  • CAPDIS-S2_HV: For high voltage (53–480 kV).

• Key Interface: Includes an LRM interface for phase comparison and an interface for Smart Grid modules (like the IKI-50).

Product Parameters

Product Advantages

• Zero Maintenance: No batteries required; the device is self-monitoring and requires no periodic testing.

• Fail-Safe Design: Features an integrated self-test function (test button) that checks the entire chain from the capacitive divider to the display.

• Inherent Safety: Even without auxiliary power, the LC display continues to indicate voltage presence.

• Smart Grid Ready: Includes a Y-interface for easy connection to IKI-50 or IKI-20a for directional fault detection and monitoring.

• Complete Monitoring: Monitors the insulation of the capacitive divider (both primary and secondary) and indicates problems immediately.

Product Application

The CAPDIS-S2 is essential for:

• Substation Safety: Checking for the absence of voltage before grounding or maintenance.

• Interlocking Logic: Using relay contacts to prevent accidental operation of earthing switches when voltage is present.

• Remote Monitoring: Signaling voltage status to a SCADA or RTU system via auxiliary relays.

• Phase Comparison: Using the front-mounted LRM sockets to synchronize or check phase sequence between two feeders.

Important Notes & Precautions

• Auxiliary Power: While voltage indication works without power, the signaling relays and LEDs require an auxiliary power supply (24-230V AC/DC) to function.

• Installation: Ensure the capacitive coupling (C1) is correctly matched to the rated voltage ($U_n$) of the system; this data is usually required when ordering.

• Broken Lead Detection: This feature can be activated or deactivated via internal DIP switches depending on your security requirements.

• Self-Test: Always perform the “Test” button check before assuming a “Voltage Absent” state for safety procedures.
