CAPDIS-S1+ / CAPDIS-S2+ (R4.5) built-in capacitive voltage indicators (VDIS) for switchgear 1–52 kV
Country: Germany · Model: CAPDIS-S1+ / CAPDIS-S2+ (R4.5)
CAPDIS-S1+ and CAPDIS-S2+ (generation R4.5) are built-in systems for verifying the absence of voltage in medium-voltage switchgear of 1–52 kV, per IEC 62271-213:2021 and IEC 61243-5. The device is installed in the front panel of the bay and continuously shows the presence of voltage on three phases through a capacitive divider.

Description
The device is connected to a capacitive divider formed by a support insulator or a bushing with a capacitive tap. It constantly monitors the response threshold and shows it with a three-step indicator, so periodic repeated tests per IEC 62271-213 and BGV A3 are not required. A full check of the divider insulation is performed from the primary and secondary side. An adjustable 6-step capacitor switching module adjusts the divider and shows the correct setting on the display, which is important for signal processing by CAPDIS-M, IKI-23, IKI-50 and IKI-55 devices. A self-test by button (patent DE 103 04 396) replaces an external tester; detection of conductor breakage and earthing monitoring are available as options. The voltage check and the self-test work without a battery, and the device is intrinsically safe. The built-in Y interface sends signals to IKI indicators and controllers, and the three-phase LRM point is used for phase comparison with the CAP-Phase tester. The 48 × 96 × 37 mm enclosure is installed in a 45 × 92 mm cut-out, with protection degree IP54, temperature −25…+55 °C and frequency 50/60 Hz.
How to choose
The difference between the versions is the relays. S1+ works without auxiliary power and is suitable when only local indication is needed. S2+ has two changeover relays for 250 V AC, 5 A with a 24–230 V AC/DC supply and a response time of not more than 1 s, so it is taken for remote signalling of the presence of voltage. For MTBF, not less than 31 years is stated for S1+ and 22 years for S2+. For ordering, specify the rated voltage Un and the divider capacitance C1. If detection of partial discharges is needed, consider CAPDIS-S1_55 and CAPDIS-S2_55, and for a voltage of 53–480 kV the CAPDIS-S1_HV and CAPDIS-S2_HV series.

FAQ
Is a battery needed for CAPDIS-S1+ to work?
No, the voltage check and the self-test work without a battery and auxiliary power.
How does CAPDIS-S2+ differ from CAPDIS-S1+?
S2+ has two signal relays with changeover contacts of 250 V AC, 5 A, a 24–230 V AC/DC supply and coloured LEDs. The relay response time is not more than 1 s.
What cut-out size is needed for CAPDIS-S1+ and CAPDIS-S2+?
The cut-out is 45 × 92 mm, the enclosure 48 × 96 × 37 mm per DIN IEC 61554. The degree of protection is IP54.
Is periodic testing of the CAPDIS indicator needed?
No, the device constantly monitors the response threshold, so repeated testing per IEC 62271-213 and BGV A3 is not required.
What must be specified when ordering CAPDIS-S1+ or S2+?
The rated voltage Un and the divider capacitance C1. The device works with classes 1–52 kV.
