Dold Measuring Relays
This will prevent thermal overload due to high switching frequency, single-phase operation, impaired cooling or high ambient temperature, for example. Measuring technology, sensors, open and closed loop technology. Monitor the system for broken neutral dolx and unbalance resulting from this where loads with the largest resistance are exposed to high voltages and may be damaged by them.
Insulation monitors Equipment for insulation fault location Residual current monitors Measuring relays Fault annunciators. If the speed-proportional frequency is higher than the reference frequency generated in the device, the output relay of the underspeed monitor will be energized and that of the overspeed monitor de-energized.
