SATEC PMU PRO – IEEE C37.118.1 Phasor Measurement Unit

The SATEC PMU PRO is a high-performance, cost-effective Phasor Measurement Unit (PMU) designed for Wide Area Monitoring Systems (WAMS) – the technology used to monitor and protect national power transmission grids in real time.

With microsecond-precision time synchronization (GPS, PTP, IRIG-B), dual-protocol streaming (IEC 61850-9-2 and IEEE C37.118.2), and a super-compact form factor, the PMU PRO brings enterprise-grade grid monitoring to Distribution System Operators (DSO) at an unmatched price point.

IEEE C37.118.1 Compliance

  • Full compliance: IEEE C37.118.1-2011, IEEE C37.118.1a-2014, IEC/IEEE 60255-118-1:2018
  • Both M-Class (measurement) and P-Class (protection) performance
  • Expected Steady-State Total Vector Error (TVE) < 0.05% at nominal frequency
  • Synchronized ROCOF (Rate of Change of Frequency) measurements

Time Synchronization

  • IRIG-B timecode source
  • IEEE 1588 PTPv2 master clock (Precision Time Protocol)

Data Streaming

  • Streaming rates: 1 to 200 frames/sec @ 50 Hz; up to 240 frames/sec @ 60 Hz
  • 5 simultaneous streaming slots (unicast UDP/TCP)
  • Dual protocol: IEEE C37.118.2 (client-server UDP/TCP + spontaneous UDP) and IEC 61850-9-2 multicast sampled values
  • Phasor data: 3-phase V & I, positive/negative sequence, frequency, ROCOF
  • Optional extensions: total P, Q, S, PF and up to 32 digital input statuses

Logging & Control

  • 32 control setpoints with half-cycle scan time
  • 8 programmable data recorders; 32 digital counters; 16 interval timers
  • Event recorder for diagnostics, faults, and logic controller operations

Electrical Inputs

  • Current: 5A or 1A
  • Voltage: CAT III, up to 277/480V AC

Interfaces seamlessly with 3rd-party Phasor Data Concentrators (PDC) for full WAMS integration.
