IKIL Load relays monitor the active-power input of electrical loads. Consequences of such undiscovered errors are costly plant shut-downs and operational downtime, repair costs and usually high costs resulting from production downtime. Up to 6 thermistors in series connection can be monitored. Neutral monitors Monitor the system for broken neutral conductors and unbalance resulting from this where loads with the largest resistance are exposed to high voltages and may be damaged by them.
