PD-Smart
Digital, highly advanced, multi-purpose and smart Partial Discharge and Diagnostics System.
Applications
Digital, highly advanced, multi-purpose and smart Partial Discharge and Diagnostics System for on-line and off-line PD testing on power apparatus and high voltage insulation systems, for both in-house and on-site applications. Allows multichannel, synchronous Partial Discharge Measurements e.g. on transformers
- according to the standard IEC 60270, VDE 0434, ANSI as well as various IEEE standards
- PD quality tests on high voltage equipment
- PD diagnosis on developing insulating materials
- Designed for on-site PD diagnosis tests as well as for manufacturing and research
- PD fault location for power cables
User Benefits
- single or multi-channel (scaleable)
- truly parallel and synchronous measurement of phi-Q-N pattern
- remote controlled via LAN and PC
- Advanced LDIC Noise-Gating-Technology:
with integrated noise-gating channel for noise-suppression viaexternal antenna - easy suppression of phase-locked noise by an unlimited number of Windows
- small compact design for stationary or on site use
- integrated battery
- features the well known LDIC Analysis and Diagnostics software
- expandable for various PD / RIV applications up to tan δ / Power Factor
