Analogue instruments MEG-1000 Insulation resistance meter Features Input circuit Consumption Frequency Overloads Ambient conditions Operating temperature Limit temperature in a neutral insulated or impedance line (IT), with the use of relays. The insulation resist- ance can be displayed with a galvanometric indicator located on the front of the unit. MEG-1000 measures and controls the insulation resistance between phase and earth To carry out the measurements, the unit ap- Build features Terminal protection degree the phase and earth, measuring the leakage current circulating through the network insulation resistors. This current determines the insulation resistance. The unit has two timed output relays, one Insulation voltage Standards BS 89, EN 60051, IEC 144, UL 94, DIN 43780, IEC 51, UNE 21318 insulation resistance is lower than a determined value). In both relays, the trip point and connection delay time can be adjusted with potentiometers located on the back of the unit. When the insulation resistor is within the lit on the front panel. When the resistor is out not reaching the normal levels, the ALARM LED will be lit on the front panel.
