CAPDIS-4o_HF

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

Applications

• Connection of protective relays with conventional 100 VAC voltage measurement input
• Connection of universal measuring devices and network analyzers
• for critical safety applications (no ferroresonance)
• Retrofitting even in confined spaces

Precise and economical

• 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 (36 kV on request)

• Voltage amplifier type CAPDIS-4o

This variant

• Maximum accuracy deviation 0.5 %.
• Extended cut-off frequency fg = 2 kHz
• Burden of voltage input 200 kOhm to connect for example sensors from Zelisko
