Hi, I am having problems with high measurements of THD% current (27%) and voltage (8%). But I'm not sure whether the source of these high THD is my load or the network.
I wonder how I could determine when a harmonic problem in the customer side is produced mainly by its loads or by the others...
Hi, I would like to know how to determine whether a customer is generating harmonics or is receiving them from the net.
Something similar like the cause of a voltage drop. If the customer is causing the voltage drop in his inner network, then should be a spike in the current drawn by the...
Hi, I would like to know if there is a device like a circuit breaker that could be used to limite the power of a household to a selectable value like 10 kW or below and with automatic reset.
I have heard about something call MCB (Mini Circuit Breaker), but I'm not sure if these devices have...
Hi, I would like to know the cause of the overvoltage in non-faulted phases during a single line fault of a three phase system. What interaction in the generator or system impedance causes this?
Regards.
Hi I´m interested to buy one 3 phase kwh meter with load profile and TOU capabilities for energy audit purpose. It´s has to be indirect metering (with CT), because it´ll reading in the secundary of a 12,500/208 V trafo 300 kVA. Also should be panel o dim mounted.
Where could I buy one over...
Hi Everyone, I have a double ended system with two transformer of 1 MVA 12.5kV/480V Y/Y transformer. Both are energize all the time but only one supply the power to the load.
The maximum demand of the system is 350 kW. My concern is about the efficiecy of this system since one trafo is just...
