SweMet MFA – PLC Power Line Smart Grid Analyzers

Is your Automatic Meter Management (AMM) system based on Power Line Carrier (PLC) communication? Do you need to improve and optimize the communication infrastructure for peak performance? Integra srl, in cooperation with SweMet AB, delivers the ideal solution. Integra has established a close technical and commercial partnership with SweMet, a pioneering Swedish company with extensive domain expertise in Smart Grids since the 1990s.

Our flagship field instrument is the MFA 500, a handheld CAT IV 300V tool (input voltage range up to 600 VAC) engineered for narrowband PLC communication. Compact and ergonomic, with optoisolated inputs and fused safety probes, it monitors the full frequency spectrum from 3 to 500 kHz in real time when paired with the MFA Viewer software. It supports all major S-FSK protocols (Addax, Echelon, Iskra, Landis+Gyr PLAN, Policom, Senea, Schlumberger) and OFDM standards (G3-PLC CENELEC A/B, FCC, ARIB; PRIME 1.3.6 and 1.4; IEEE 1901.2).

For stationary and continuous monitoring, the MFA 600 Three-Phase Data Logger precisely tracks the 3 to 150 kHz CENELEC range simultaneously across all 3 phases (3x230 VAC / 400 VAC max). It records peak and RMS values at 5-minute intervals with local memory storage exceeding 41 hours, transmitting data via Ethernet TCP/IP or an optional GPRS cellular modem. Timestamped fault events allow operators to pinpoint critical time windows and plan field maintenance efficiently.

Completing the diagnostic ecosystem, we provide the MFA Viewer 3.0 software suite (linear dBµV scaling from 40 to 140 dBµV, 80 dBµV alarm line, and shaded disorder area), the portable MAX79356 G3-PLC Sniffer Kit with OFDM per-tone channel analyzer and phase check, and dedicated PLC 230-16A mains filters (IP54, 250V 16A, with >40 dB attenuation between 35 and 150 kHz). Eliminating root-cause interference maximizes remote reading success rates and allows decommissioning costly repeaters.
