is determined for the AC voltage tests of single-phase
or three-phase meters in serial production, but also for individual meter insulation
tests in accordance with the standards IEC 62052-11, IEC 62053-21, -22, -23 for
electricity meters of protection class I and II.
Highlights
• Test voltage source of 4 kV event. 4 kV has built-in timer
for test periods up to 1 min;
• In a case of occurrence of flashover, disruptive discharge
or puncture the source generates acoustic signal and the source
is switched-off automatically;
• Test Rack is located in the protection box for automatic testing
of 1 to 4 units of single-phase or three-phase electricity meters;
• The meters are connected through quick-connection mechanism;
• In a case of occurrence of flashover, disruptive discharge
or puncture of the meter insulation the checking light
is illuminated in the relevant position.
