NEVA-Test 6325 and NEVA-Test 6125
Installation of technological run NEVA-Test with a source of fictitious power is designed for testing electricity meters.
Installation is completed with the voltmeter, ammeter and other measuring devices.
Prolonged exposure to various loads on meters.
Pecularities:
- Stand for hanging meters and energy source on an aluminum frame. Meters hanger is double-sided, in 4 rows, each row has 12 counters.
- Meters hanger stand and the energy source are controlled separately, the conditions on the stand can be adjusted according to the real ones, one to four stands can be connected to one energy source.
- Output phase shift is produced by a phase regulator.
- Digital display of voltage, current, phases (power meter).
- A function of conducting the process by impulses from counters or by time.
- A function to protect meters from excess output voltage and a function to reset output signals.
- An interface port 485, for the convenience of checking the performance of multifunctional electricity meters (included).
- An isolation transformer is installed on each stand for hanging meters to test meters that have shunts as current sensors.
- A function to switch outputs under different load conditions to meet different conditions in the specification.
- The unit has three output channels for generating voltages and three output channels for generating current with independent adjustment.
- The installation has a function to set the test time on the source of fictitious power.
