    Standard Meter

 

1.1    General Introduction

 

The SZ-03A-K8 series three phase standard meter utilize such lasted technology as high-speed DSP, CPLD, MCU and ADC with self-calibration, etc. Thus, the meter can sample AC signal in high speed and treat them with special digital arithmetic. All of these make the meter’s structure simply and measure 0.02% accuracy of the relative error.

 

 

 

1.2    Features

 

 

 

    Suspension test Rack

 

A.    24-meter position distribute on 2-meter racks, double side two rows,

       each row include 6 positions.

B.    There is a three-colour indicator light on the top of each rack.

C.    Each meter position installs a quick connector QCD, a push hand, a scanning head,

       an error display window, and a DB9M socket.

 

 

D.    All the current cable wiring in the rack is 30mm2

E.    DB9M socket is for RS232 port, RS232 is offered by Multiport Serial Server

       which extends 24 ports connect with 24 MUTs.

 

 

F.    Optical port reader for meter communication

G.    Isolation Current Transformer (ICT)

Nowadays, more and more energy meter’s current and voltage channel is fixed connection; it is close IP-link meter. For testing of meters with closed IP-link, the unit under test must be supplied with isolated and potential-free current and voltage signals. The previous test bench couldn’t offer such signals, can only test open IP-link meter. TICT-100 series is a precision isolated current transformer (ICT) with active electronic error compensation, can offer the insolated high accuracy current, to test close IP-link meter. TICT-100 series can be installed on the new test bench or used to upgrading the old test bench.
