MEASUREMENT OF THE ERROR OF METER CONNECTED WITH CT AND TRANSFORMER WITH USING ANALYSER Calport 100A

Measurement of the error of meter and transformer ratio Connecting of the Analyser Calport 100A to the three phase meter connected with CT:

  • CT100A current clamps are connected on the primary side for monitoring

all measuring system together with a ratio of the current transformer,

  • the current transformer has a ratio with nominal value K=100A/5A,
  • the meter has the impulse constant CL=4000imp/kWh – in this constant is

not taken into account a ratio of the transformer,

  • in menu we are choosing the function of measurement by clamps 100A –

– the sign 100A,

  • in menu we are choosing the function of lack of the ratio – the sign

,

  • we are entering the impulse constant C = CL / K = 4000 / (100/5) = 200,
  • we are entering the number of impulses or the time of error measure,

for example T=20s,

  • after pressing the key "exit" Calport shows the error of meter and

transformer.

WHY THIS MEASURE IS VERY IMPORTANT? Because only in this case we can identify the wrong energy counting caused by wrong connection of the meter with transformer. Because, a good meter and a good transformer can wrongly count an energy if they are connected in a wrong way. Because the separate checking of the meter and separate checking

  • f the transformer does not find this defect.
