Product Name: Single Phase And Three Phase Meter
Specifications :
A- STS Electronic Counters
1.1 Description of the Counters
The Electric Energy Measurement Meters Will Be Static, Robust And Standardized Electronic Meters
STS (Standard Transfer Specification) Edition 2. They Are Single-phase And Three-phase Prepaid, Must
Comply With The STS Protocol, Must Be TID Rollover And Comply With STS Edition 2, Must Obtain The
STS2.0 Certificate, And Meet The Requirements Relating To IEC 1036 and SABS 1524-1 Standards Or
Equivalent Recognized Internationally. The Origin Of The Main Chipset Of The Measurement Unit Must
Be Indicated And Of A Globally Recognized Brand. They Will Be Of The Split Type And Must Comprise
Two Modules, One Of Which Is Relative To The Measurement Of The Parameters And The Other Intended
To Interface With The Customer :
A) Measurement Module: It Is Responsible For Measuring Electrical Parameters (active Energy, Power,
Current, Voltage, Etc.). It Will Not Be Of The Plug-in Type. The Measurement Module Is Housed In A
Casing That Can Be Sealed At Two Points. The Meter Housing Must Have Security Against Any Attempt At
Fraud. It Must Perfectly Protect The Internal Circuits And Be Stable At Room Temperature, Impervious
To Moisture And Dust. It Must Satisfy The Following Conditions :
The Measurement Module Will Be Installed In A Safety Box By A BS Type Fixing Method (By Screws)
And Not DIN Type (by Hanging On Rail). Its Replacement By A Measuring Module From Another
Manufacturer Will Not Require Other Fixing Points.
The Terminal Cover Of The Measurement Module Will Be Made Of Unbreakable, Transparent Molded
Plastic And Must Completely Cover The Connection Cables. There Will Be At Least One Seal On The
Terminal Cover
The Measurement Module Will Be Equipped With At Least Four LEDs And Whose Functionalities Are
Described Above :
* Charging Rate Indicator
* Voltage Presence Indicator
* Alarm Or Abnormal Status Indicator
* Communication Status Indicator Between The Measurement Module And The Client Interface
Module.
B) Customer Interface Module: It Is Installed Inside The Homes Of Subscribers To Allow Them To Credit
Their Meter And Consult The Saved Parameters And The Operating Status Of Their Meter. It Must Be
Flexible, Reliable, Strong And Interchangeable. The Communication Between The Measurement
NB: The Voltage Drop Up To (150 V) One Hundred And Fifty Volts Must Not Influence The
Metrology (Accuracy) Of The Meter.
Digital Display Of The Index With At Least Seven Digits (6+1) With The Kwh As The Unit.
A Twelve-key Keyboard With An Audible Reaction.
The counter, responding to the STS Protocol, Must Memorize All The Transactions Carried Out Within
It And Display Via The Liquid Crystal Display :
• The Credit Level In The Form Of Trapezoidal Bars
* The Remaining Credit (in Kwh)
* The Energy Consumed (in Kwh)
* Instant Power
* The Low Credit Warning On At Least Two Alert Levels Which Are Programmable: The Alarm And The Pre-
Alarm (5 Kwh For Single-phase And 10 Kwh For Three-phase). When The Meter Credit Is Below The Pre-
Alarm Or Alarm Thresholds, This Will Be Indicated By An Audible Alarm, An LED And Signs Displayed On
The LCD.
* The Indication Of Fraud Status
* Maintenance And Diagnostic Information
