Hello folks, We are looking to perform some tests with our system that is connected to 380VAC mains and draws up to 150KW of power. We want to be able to simulate different line impedance (R & L) to test our power supplies in low/bad line conditions. A few R and L values would suffice. (can be static or dynamic line changes). Has anyone played with such a device/instrument before? Could you direct me where we could purchase such a device? We could always derate the operating power to 75KW in case 150KW is not available... Of course we could always build one using hi-pwr resistors and chokes and/or auto-transformers but if something off the shelf exists , we would rather go this route. Thanks in advance.
