Measuring of insulation resistance
Instrument for measurement of insulation resistance PU 296 MEGMET 5000D
The instrument PU 296 is intended for measurements of voltages, insulation resistances and determination of coefficients PI, DD and DAR at revisions of the high-current equipment. It complies with the requirements of the standard ČSN EN 61557-2.
Insulation resistance: 0.1 MΩ to 1 TΩ
Instrument for measurement of insulation resistance PU 187.2 MEGMET 1000D
The instrument serves for measurements of insulation resistances up to their value 20 GΩ and the resistance of the protecting lead up to 2 kΩ, or its length, also a check of over-voltage protections can be performed by it. Furthermore, DC and AC voltages can be measured up to 1000 V and temperature within the range -20 to 120 °C, with connected external sensor within -50 to 850 °C. The nominal measuring voltages for measurements of insulation resistances are 50, 100, 250, 500 and 1000 V.
Insulation resistance: 0.1 MΩ to 20 GΩ
Instrument for measurement of insulation resistance PU 186 MEGMET
The instrument serves for measurement of insulation resistances up to the value 20 GΩ and the resistance of the protecting leads up to 10 Ω consequentially to the standard ČSN 331610 (for electrical appliances). Furthermore, the DC and AC voltages can be measured up to 1000 V. The nominal measuring voltages for measurements of insulation resistances are 500; 1000; 2,500 V. The measurement current at the measurement of the protecting lead resistance is min. 200 mA.
Insulation resistance: 0.1 MΩ to 20 GΩ
Instrument for measurement of insulation resistance PU 182.1 MEGMET
The instrument is intended namely for insulation resistance measurements of electric objects and equipment in connection with the standard ČSN 331610 (for electric appliances) at the nominal DC voltage 100 V, 250 V and 500 V. Furthermore, ac and DC voltage up to 550 V can be measured as well.
Insulation resistance: 0.2–1,999 MΩ
Analogical insulation resistance meter for insulated networks IT PU 590
The instrument PU 590 is intended for measurements of the insulation resistances and voltages in the insulation networks IT in the signalization and safeguarding systems, at presence of disturbing voltages. The PU 590 can be used even for current measurements of the insulation resistances.
Insulation resistance: 100 kΩ to 50 MΩ
