FOR CALIBRATION OF MEASUREMENT EQUIPMENT FOR ELECTRICAL QUANTITIES

ACCREDITED LABORATORY

 

Accredited by the Bulgarian Accreditation Service

 

Certificate No 22 ЛК / 06.11.2015

 

We perform calibration of the following measurement equipment types:

 

  1. Voltmeters for direct voltage – scopes from 0.02 to 1000 VDC
  2. Voltmeters for alternating voltage – scopes from 0.2 to 1000 VAC (50Hz)
  3. Ammeters for direct current – scopes from 0.2 mA to 10 ADC
  4. Ammeters for alternating current – scopes from 2 mA to 10 AAC (50Hz)
  5. Ohmmeters ( R ) – scopes from 0.01 Ω to 100
  6. Equipment for measurement of parameters of el. installations:
    • ground resistance RA (RE) – scopes from 0.5 Ω to 2
    • “phase-zero” loop impedance, phase-insulated conductors (LOOP) in scopes from 0.1 Ω to 200 Ω
    • contact voltage Uc (Uf) - scopes from 0.1 V to 90 V
    • trip current of  RCDs - 10mA, 30mA, 100mA, 300mA, 500mA
    • insulation resistance (megohmmeters) – scopes up to 1 ТΩ by test voltage up to 5000V
