Recommended Upstream Protection
It is recommended to place an upstream protection that houses only the incoming electrical installation to the equipment. The function of all visible elements in the switchboards shall be clearly indicated.
The upstream connection switchgear consists of:
-
Overcurrent and short-circuit protection: An upstream circuit breaker must be installed at the input of the system according to the recommendations provided in the following table. If the short-circuit current capacity at DVR point connection is greater than the PowerLogic™ DVR short-circuit withstand rating (refer table), use current-limitation circuit breaker.
-
Overvoltage protectors: It is recommended that the general supply connection to the building be fitted with protector against surges due to atmospheric discharges.
-
Differential protection: If a differential protection is used, it should be type B with a minimum time delay of 100 ms, and a minimum value should be set depending on the system configuration.
