Small testing equipment for electricity meters checking STE

is a small portable equipment for checking, adjustment and measurement of all types of electricity meters. It consists of the single phase signals generator PPS, the working standard WS and compound connecting stand PHS. It is possible to check precision of the meters using this system directly at the customer´s premises. The system is provided in three individual and robust portable cases, suitable also for individual usage.

•  Rough and fine smooth current adjustment;
•  Output current indication;
•  Galvanic isolation of voltage and current outputs;
•  Zero values of the output voltage and current with the first
   switch-on;
•  Voltage outputs U and U_1/2 create galvanically isolated
   line voltage;
•  Adjustable phase shif;
•  Temperature and current protection of the power stages;
•  Single phase power supply.

•  Equipment precision is determined by the precision of WS
   (0.1 % or 0.2 %);
•  Working standard is equipped with a high sensitive optical
   sensor of disc black mark or testing LED. The sensor has
   auto-calibration features and it supresses external light
   influences;
•  Working standard could be supplied along with
   a printer for testing protocols printing.

•  Fixing arrangement is equipped with quick connection system;
•  Simple and fast assembling;
•  Executions: 1-phase with the possibility to connect three-phase
   meters or 3-phase execution.
