Abstract: The intelligence, refinement and visualization of the distribution system are the trend of distribution management. The smart power meter is designed and installed for the power distribution circuit , in order to real time monitor the working state of each load circuit by setting the parameters of the smart meter. It can improve the safety of energy usage, improve the efficiency of equipment maintenance, reduce labor cost of maintenance, and realize the unattended monitoring of distribution system. Through data collection, real-time monitoring of electrical parameters, analysis of the power quality and distribution system running status, it will save users’ power maintenance costs. This article gives a brief introduction of Acrel PZ ammeter and frequency meter used in Iceland Tandraberg ehf company's motor monitoring project. 

1.項目概述(shù)：

Project Overview

Tandraberg ehf公司(sī)位於冰(bīng)島(dǎo)Eskifjörður，是該(gāi)國較(jiào)大的冷凍(dòng)托(tuō)盤(pán)廠家之(zhī)一，該公(gōng)司的(dí)生(shēng)產(chǎn)用(yòng)電(diàn)大(dà)多(duō)為(wéi)電(diàn)機(jī)負(fù)載，用(yòng)於(yú)工(gōng)藝(yì)切割(gē)。由於(yú)原電(diàn)機控製櫃未加(jiā)電力儀(yí)表，且(qiě)變(biàn)頻器工作(zuò)狀(zhuàng)況不了解，不(bù)知道(dào)電(diàn)機(jī)的運(yùn)行(háng)狀況，故采購(gòu)我司PZ係列三相(xiāng)電流表(biǎo)用於(yú)電機(jī)電流監(jiān)控以(yǐ)及(jí)頻率(shuài)表用(yòng)於(yú)監測回路頻率變化.

Tandraberg ehf company, located in Eskifjörður,  is one of the largest manufacturers of refrigerated pallets in Iceland, Its main production electricity is motor load, which is used for process cutting. Since the original motor control cabinet doesn’t install with power measuring instrument, and the working condition of Variable-frequency Drive and moter are unknow. Therefore, they purchased Acrel PZ series three-phase ammeter for motor current monitoring and frequency meter for monitoring frequency change.

2.PZ係列(liè)可編程智能電(diàn)測(cè)儀(yí)表介(jiè)紹(shào)

PZ Series Programmable Intelligent Electric Meters

PZ係列儀(yí)表采(cǎi)用(yòng)交流采樣(yàng)技(jì)術(shù)，可測(cè)量電(diàn)網(wǎng)中的(dí)電(diàn)流，電(diàn)壓，功率，功(gōng)率因數(shù)和電(diàn)能(néng)參數(shù)。它(tā)可通(tōng)過麵(miàn)板(bǎn)按(àn)鍵設(shè)備電(diàn)力參(cān)數(shù)。該(gāi)儀(yí)表(biǎo)具(jù)有(yǒu)RS-485通訊(xùn)接(jiē)口，采(cǎi)用Modbus協(xié)議；也(yě)可以將(jiāng)電(diàn)源信(xìn)號(hào)轉換(huàn)成標準的(dí)直流(liú)模擬(nǐ)信號信(xìn)號。該儀(yí)表(biǎo)還具有開關(guān)輸入(rù)/輸出，繼電器/報警(jǐng)輸(shū)出(chū)等(děng)。

PZ series of meters adopt AC sampling technology,which can separately measure the current, voltage, power, power factor and electric energy parameters in the grid .It can set the electrical parameter through the panel button.This meter has RS-485 communication interface,adopt Modbus protocol;also can convert the power signal into a standard DC analog signal.The meter also has switch input/output,relay/alarm output,etc.
