CAPDIS-S1_HV / CAPDIS-S2_HV (R5, R4.5) voltage indicators for HV switchgear 52–480 kV
Country: Germany · Model: CAPDIS-S1_HV / CAPDIS-S2_HV (R5, R4.5)
A built-in voltage indicator for high-voltage switchgear of 52–480 kV, including gas-insulated, made to IEC 62271-213:2021 and IEC 61243-5. The device continuously shows the voltage on three phases from the signal of the capacitive taps of the bay. The S1_HV version works without auxiliary power, and S2_HV has a relay and signal outputs.

Description
The device monitors the response threshold constantly and displays it with a three-step level indicator, so repeated tests per IEC 61243-5, IEC 62271-213 and BGV A3 are not required. It fully checks the insulation of the capacitive divider from the primary and secondary side, and the self-test is started with a button without an external tester or battery. Conductor breakage is detected using DIP switches, which turn this function on or off; the device is intrinsically safe. S1_HV has no relay. S2_HV is equipped with changeover contacts for 250 V AC, 5 A or 30 V DC, 5 A with a response time of not more than 0.2 s, a 24–230 V AC/DC supply with consumption below 1 W, an insulation voltage of 2 kV and coloured LEDs. The R5 generation adds partial discharge detection with 4 sensitivity levels, signal output through a relay and transmission to IKI-23, IKI-50 or IKI-55 for trending. The panel-mount enclosure of 48 × 96 × 37 mm is installed in a 45 × 92 mm cut-out per DIN IEC 61554, with protection degree IP54, operating temperature −25…+55 °C, storage −30…+75 °C, frequency 50/60 Hz and an LRM interface. MTBF is not less than 31 years for S1_HV and 22 years for S2_HV.
How to choose
The choice is determined by the need for signalling. If visual indication is enough, take CAPDIS-S1_HV, and for signal output to a relay and partial discharge processing CAPDIS-S2_HV is needed. When ordering, specify the rated operating voltage Un and the coupling capacitance C1. For switchgear of 1–52 kV there are CAPDIS-S1_55 / CAPDIS-S2_55, and for high-level voltage monitoring the CAPDIS-M HV module is offered.

FAQ
How do CAPDIS-S1_HV and CAPDIS-S2_HV differ?
S1_HV works without auxiliary power and without a relay. S2_HV has signal outputs, a 24–230 V AC/DC supply and a monochrome LCD display.
Are repeated tests of the indicator required?
No, the device constantly monitors the response threshold, so per IEC 61243-5, IEC 62271-213 and BGV A3 tests are not required.
For which switchgear are these indicators intended?
For high-voltage switchgear of 52–480 kV, including gas-insulated, with capacitive taps of the bays.
What does the R5 generation give?
It detects partial discharges with 4 adjustable sensitivity levels and transmits the signal to IKI-23, IKI-50 or IKI-55 for trending.
What time of failure-free operation is stated?
MTBF is not less than 31 years for S1_HV and not less than 22 years for S2_HV.
