The Micatu Optical Solution Platform, is an all optical, configurable and modular condition monitoring platform that can support four types of sensors; voltage, current, vibration and temperature each with a common connection module that connects to the m410 modular sensor processor.

When configured for Medium Voltage Smart Grid Measurements, the GridView™ Rg235 Medium Voltage & Current Sensor System is a direct replacement for standard power transformers and current transformers as well as pole-top and “bird-on-the-wire” sensors. Each three-phase sensor system provides highly accurate and precise simultaneous 3-phase measurement of voltage and current from 4kV to 35kV.
Gridview Sensor
The GridView™ Medium Voltage & Current Sensor is a direct replacement for standard power transformers and current transformers. Because of the “all optical” sensor design, there are no conductive materials used for the measurement of both voltage and current. The insulator body is casted in hydrophobic cycloaliphatic epoxy (HCEP) using a state of the art injection molding process. HCEP construction provides superior arc track, ozone, and ultraviolet-resistive properties while maintaining physical strength. The hydrophobic surface properties of HCEP ensure highly reliable performance in wet or humid conditions. All calibration and performance settings are stored in the ruggedized modular electronics enclosure at the base of the optical cable. The m410 Modular Optical Sensor Processor provides a “highly accurate” as well as “low cost” precision solution for distribution grid monitoring and control.

Grid Processor

The m410 Modular Optical Sensor Platform is a cost-effective solution for monitoring the electrical distribution grid for precise voltage and current measurement, as well as vibration and temperature condition monitoring.

The m410 has four modular bays that allow for any sensing combination of Micatu sensors, including sensing of voltage, current, vibration and temperature and has the capability for enabling future expansion modules.

For distribution grid monitoring, the m410 when combined with Rg235 GridViewTM Overhead Sensors, allows for a true “plug & play” solution. The small enclosure size and multiple analog & digital output options allows the m410 to interface to virtually any industrial and substation automation platform.

GridProcessor

The m410 Modular Optical Sensor Platform also provides a digital to analog conversion via LEA (low energy analog) output from 0-10VAC or 0-120VAC via an optional expansion module for local control and retrofit controller applications. Ten software configurable discrete inputs and outputs allows for relay control, security switching or alarming inputs or outputs. External temperature measurements are supported using a standard thermistor input and reportable both in digital or analog outputs.
