Description

The Miro-F TxM 304 is a Class A Power Quality monitor and logger designed specifically for monitoring high voltage (HV) feeders and transformers within a substation or switchyard and is equipped with remote cellular or Ethernet communications, using various protocols, including DNP3, TCP-IP and FTP. Inputs are via substation voltage and current transformers.

It offers comprehensive and reliable logging and monitoring of power quality data, including Voltage Sags, Swells, Interruptions, Flicker, THD, Harmonics, Interharmonics, Frequency, Mains Signalling, Power and Energy.

Waveform and RMS captures can be generated, using various triggers, e.g. rate of change of voltage (dv/dt), sliding reference, and instantaneous voltage and current values. Voltage and current inputs are sourced from relevant voltage and current transformers, and can be scaled to reflect primary side measurements.

Alarms can be generated when set thresholds are exceeded and notifications then sent to control centres, SCADA Masters etc. WiFi communications can be used to view real time measurements, power direction and to configure the instrument. The Miro-F TxM 304 is a Class A Power Quality monitor and logger that provides timely data and notifications that help engineers optimise planning, operations, maintenance and network modelling activities. All data can be collected and analysed by AsMoSys, a CHK PQ proprietary database solution.
