Hello everybody,
i am interesting in buying a device to test MCCBs (Moulded Case Circuit Breakers), especially for Instantaneous overcurrent trip test. Any suggestions for devives? Is Sverger 780 suitable to do it?
Hello!
I designed an outdoor LED Street Lighting with 8 poles, 2kW total. When sizing the cable I chose to use a 5x10mm2 cable (for voltage drop). Each pole has two lamps with the following data.
Power consumption at dimming:120 W
Inrush current: 47.2 A
Inrush time: 600 ms
Driver current: 700...

Hello Guys,
Limiters do not replace the protection system but only prevent the protection system from tripping unsecessarily under extreme transient conditions. But how the limiters and protection system cooperate? The limiters operates faster than protection for the same fault condition?
Hello Guys,
I study a generator (5 MVA) with an old Static Excitation System. I plan to change the Excitation System with a new model. Which parameters should be compared between new Excitation models (ceiling voltage, ceiling current, Response Ratio), such that i can arrive at a decision...
