SMY-CA

Robust Waterproof Compact Analyser

Analyser of electric network parameters SMY-CA is a measuring and data logging instrument for single- and three phase low voltage (up to 230/400V) distribution networks in substations, switchgear boxes, cubicles or directly at the consumers premises such as smart buildings, hospitals, industrial infrastructures etc.
Core of the instrument is a modified SMY 133 analyser. Its features and functions closely corresponds to IP65 mini case version -CA.
With PQ S firmware module instrument becomes a fully featured power quality analysers with support for flicker indices (Pst, Plt), record of voltage events and weekly power quality evaluations according to EN 50160.

Current sensors
Instruments with this option features 333mV AC input for measuring current using special current transformers. This special input supports various flexible rogowski coil current transformers as well as other kind of
transformers with 333mV AC output such as split-core CTs or clamps.

Optional firmware modules

PQ S module
Module for evaluation of power quality according to EN 50160 (class S). Enables measurement and recording of flicker indices, interharmonics and voltage events. Power quality is evaluated weekly and stored to special PQ Main archive for future processing.

GO module
Module for detection and precise recording of various waveform distortions. This module records the so called oscillograms of voltages and currents in extended detail, capacity and trigger options into the flash memory.

RCS module
The RCS module (ripple control signal or mains voltage) activates an ability to detect, evaluate, decode and store RCS messages transmitted over the distribution network. It precisely measures voltage on the selected frequency and stores the extracted information.
