pengukuran baterai per cell dengan arduino

eksperimen kali ini tentang penguukuran baterai percell. yang dimonitoring dari arduino.
ini rencananya monitoring tegangan baterai rectifier di sebuah substation.

berikut sketchnya:

int BT1 = A5;   
int BT2 = A4;

int Bat1 = 0; 
int Bat2 = 0;
int BatT = 0;

void setup() {
    Serial.begin(9600);
}

void loop() {
   float Bat1 = analogRead(BT1)*0.01437;
   float Bat2 = analogRead(BT2)*0.02517;
   float BatT = analogRead(BT2)*0.05028;
   Serial.print("Baterai 1 = " );
  Serial.print(Bat1);
  Serial.print("     Baterai 2 = ");
  Serial.print(Bat2);
  Serial.print("     Baterai Total  = ");
  Serial.println(BatT);

   delay(1000);
}


komponen yang dibutuhkan
1. resistor 4 buah yang d rangkai voltage divider.
2. dtambah kapasitor2 buah sebagai filter

integrasi epm5500 to SIMOR

bagi yang membutuhkan addres modbus power meter epm5500P multilin
bisa download disini

percobaan integrasi power meter multilin epm 5500P to rtu simor.
data yang di ambil tegangan arus dan frekwensi
data yang dikirim sisi primer.
sperti contoh :
saya injek arus 1A,
ratio CT  400/5
tampilan LCD menunjukan 80, akan tetapi yang keluar di data modbus 1000
jadi agar datanya sama tampilan LCD di faktor kalikan 0,8 (sesuai ratio CT.

berikut videonya
