With an isolated voltage of 5000 VAC and mechanical operating cycle in the region of millions the high voltage relay is particularly well suited for difficult conditions. The switching current averages at 10 AAC, the continuous current at 30 AAC. High voltage relays are used in many technical devices that require voltages that go up to 10,000 V and currents up to 30 A. High voltage relays offer low and stable contact. Protection engineers calculate the maximum load current, the minimum fault current, and the full range of possible voltage levels to ensure relay performance under all conditions., single line-to-ground. hen interrupting heavy-duty motor currents. It is important to understand that a relay's current rating depends on the switching voltage and the type of load.

[pdf] Protective relays and devices have been developed over 100 years ago to provide “last line” of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. In this voltage balance differential relay arrangement, two similar current transformers are connected at either end of the system element under protection (such as a feeder) by means of pilot wires. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers. Two models are available: the ES-47N provides phase unbalance, phase loss, phase reversal/phase sequence protection and the ES-47N/27 provides the same protection as the ES-47N in addition to undervoltage.
