Overview
Touch screen graphics LCD
Rish Master 3430i has touch sensible color graphics LCD display with resolution of 320×240
Phasor Diagram
Pictorial representation of all 3 Phases (Voltage & Current) in terms of vectors
Custom color setting
User can assign individual colour for each each phase as per the application requirement through display
Wave Form
Pictorial representation of all 3 phases Current & voltage in terms of sinusoidal waveform
On site programmable PT/CT ratios
It is possible to program primary of external potential Transformer (PT), primary of external Current Transformer (CT) on site via front panel keys by entering into Programming mode.
User selectable PT Secondary
The secondary of external potential Transformer (PT) can be programmed on locally via front panel keys by entering into Programming mode or remotely via MODBUS (RS485)
User selectable CT Secondary 5A/1A
The secondary of external Current Transformer (CT) can be programmed on site to either 5A or 1A using front panel keys.
User selectable 3 phase 3W or 4W
User can program on site the network connection as either 3 Phase 3 Wire or 4 Wire using front panel keys. For single phase applications, single phase version is available.
Low back depth
The instrument has very low back depth (behind the panel) of less than 80 mm in spite of optional features like pulse output
Onsite selection of Auto scroll / Fixed Screen
User can set the display in auto scrolling mode or fixed screen mode using front panel keys.
Energy measurement (Import and Export)
Active energy (kWhr), Reactive energy (kVArhr) and Apparent energy ( kVAhr). Any of the parameters can be freely assigned to 2 optional pulse outputs.
True RMS measurement
The instrument measures distorted waveform up to 15th Harmonic.
High brightness 3 line 4 digits LED display
Simultaneous display of 3 Parameters
Number of parameters measured: up to 48
The instrument measures 48 electrical parameters of 3 Phase network.
Parameter Screen recall
In case of power failure, the instrument memorizes the last displayed screen. The displayed screen will get memorized only if user keeps this screen for minimum 40 sec duration before power failure for fixed screen mode.
Total Harmonic Distortion (THD)
The instrument measures individual phase as well as system voltage & current THD
Energy Count storage
In case of power failure, the instrument memorizes the last energy count.
User selectable Low Current suppression (Below 30 mA)
User can suppress the readings below 30 mA in the current measurement by onsite programming if required.
Min Max storage of parameters possible
The instrument stores minimum and maximum values for System Voltage and System Current. Every 40 sec minimum and maximum readings are updated.
Optional MODBUS (RS485) Output
The optional ModBus output enables the instrument to transmit all the measured parameters over standard MODBUS (RS485 ).
Optional Pulse Output (2 Relay output)
The optional pulse output is a potential free, very fast acting relay contact which can be used to drive an external mechanical counter for energy measurement.
Optional Analog Outputs (2 Outputs)
2 Analog outputs can be programmed from a list of input parameters.
Enclosure Protection for dust and water
Conforms to IP 54 (front face) as per IEC60529
Compliance to International Safety standards
Compliance to International Safety standard IEC 61010-1- 2001
EMC Compatibility
Compliance to International standard IEC 61326
