ARx & ANx - HIGH VOLTAGE ADAPTORS
- HV Adaptor for AC Insulation Guards and Transducers for use in Isolated Networks (IT-Net)
- Up to 28kV Line Voltage
- Creates safety barrier from live HT network to LV switchboard
- Limits measuring output signal to safe levels
- No restrictions on distance between adapter and LV switchboard
Description
Voltage adaptors ARx or ANx are used together with insulation Guard
KPM165x and
KCM165x or insulation transducer
MCM165x, for monitoring of line voltage from 0-28kV.
The adapters are a passive low-pass filter for use in 50, 60 or 400Hz networks, and is potted in polyurethane.
The unit includes high inductance reactance modules, connected in a
special configuration to avoid DC saturation. The Adapters maintains a
high AC suppression of its signal output to very low, safe levels, under
all conditions.
Alternative connections to the AC network are shown below. Connection to the star-point (Neutral) is preferable.
3 phase connection:
- AR7: Up to 7kVAC
- AR14: Up to 14kVAC
Neutral connection:
- AN7B: Up to 7kVAC
- AN14B: Up to 14kVAC
- AN25B: Up to 25kVAC
- AN28: Up to 27kVAC
