CAPDIS-4o_HF

The CAPDIS-4o amplifier provides an output voltage of 3 x 100 or 110 VAC in conjunction with three resistive sensors and thus serves as a substitute for three inductive voltage transformers.

Precise and economical

• System class accuracy: 0.5 %; alternatively 0. 3 % with 3P
• Economical alternative to outgoing voltage transformers

Safety and handling advantages

• minimal space requirement
• no additional measuring field
• no disassembly required for surge voltage tests
• no ferroresonance hazard

Universal system components for all applications

• Ohmic divider type OKE for  air-insulated switchgear series 12 kV, 24 kV or 36 kV
• Resistive divider type OAS for right-angle connectors in SF6 switchgear series 12 kV or 24 kV (36kV on request)
• Voltage amplifier type CAPDIS-4o

High frequency variant

Limit frequency of the amplifier is fg= 2 kHz

For Zelisko sensors

The input burden for the resistive sensors is 200 kOhm.
