Analog Meter – Maximum Demand

Maximum Demand Ammeters monitor the most economic use of cables, fuse gear, transformer stations & LT distribution feeders by indicating the thermal / time characteristic of the load. The directly heated bimetal element indicates mean RMS current over 8, 15 or 20 minutes and a red slave pointer shows highest value reached. Scales are calibrated to match the CT primary plus 20% overload. Where the instantaneous and maximum demand currents are required, the BIEQ instrument, which combines a thermal bimetallic and a moving iron movement in the same case mounted diagonally opposite to each other.
