NEVA-TEST 3303L

Installation allows to carry out the following tests of meters:

- determination of relative error;

- determination of the standard deviation (S) when determining the error;

- checking the absence of self-propelled;

- starting current test;

- checking the meter constant;

- checking the counting mechanism;

- determination of errors when changing the phase sequence;

- determination of additional errors when changing the voltage and frequency of the network;

- determination of additional errors in the presence of harmonics in current and voltage circuits;

- determination of additional errors in case of load asymmetry;

- determination of additional errors in case of unbalance of phase voltages.

• Availibility of a built-in stabilized voltage source with an output voltage regulation range from 1 to 300V

• Availibility of a built-in stabilized current source with a range of regulation of the output current of each phase from 0.01 to 120A
• Displaying the following results of measurements and calculations on indicator boards:

- RMS current values;

- root-mean-square voltage values;

- active, reactive and apparent powers in total and per phase in W, Var and VA, respectively;

-active and reactive energy in W*h, kW*h, var*h, kvar*h;

- errors of verified electric meters in%.

• Software allows you to control the operation of the installation from a personal computer, which ensures the saving of verification results in databases with the possibility of generating verification results in the form of protocols. Software allows the user to independently create the type of verification protocol
