Automatic test-systems for check of one electricity meter

Single phase test system

Application and brief description

Components:

PL 60/1 – single-phase electronic phantom load

PEWM 1/1 S – single-phase energy standard class 0.1

EH 11 – scanning head for reading the pulses (rotations) of the electricity meter

Application:

Test of all types of single-phase electricity meters. Check of error of the electricity meter, dial test, no-load test, starting current test.

Technical data:

• The values of voltage, current and dephasing are adjusted via a keyboard
• Dosage of energy for test of registers
• Indication of the actual values of U, I, f, P, Q
• Indication of error of electricity meter
• Automatic mode of work with a computer, print of protocols, organization of archive

Three phase test system

Application and brief description

Components:

PL 100/3 – three-phase electronic phantom load

PEWM 3A – three-phase energy standard class 0.05

EH 11 – scanning head for reading the pulses (rotations) of the electricity meter

Application:

Test of all types of electricity meters (active/ reactive energy, two-, three-, four-wire connection). Check of error of electricity meters, dial test, no-load test, starting current test.

Technical data: Identical to the single-phase system
