Frequently Asked Questions

Q. Why doesn’t TPS use inductors (or reactors) in TruePFC technology?
TruePFC Technology does not use contactors so we don’t have contact bounce. Inductors are required in a system that must mitigate contact bounce.

Q. How does TruePFC not create overvoltage fluctuations or system instability?
Over capacitance is the cause of overvoltage fluctuations. Since the switching of our system is so quick (60 times per second), our system does not cause over capacitance in the distribution system.

Q. Does TruePFC use contactors to switch capacitors?
No – we use SCRs.

Q. Can TruePFC correct the power factor of non-linear loads?
Yes.

Q. What, in general, makes TruePFC so different?
TruePFC technology switches using SCRs and senses and switches on each phase, every cycle (60 times per second).

Q. Is the system installed in series with the individual motors, or in parallel with the whole system?
Our system is installed in parallel at the distribution panel.

Q. Are there specific circuit breaker requirements?
Yes, one (1) 250 amp, 600-volt breaker with a minimum of 15 KAIC rating for the 165 system. The 330 system requires two (2) 250 amp, 600 volt breakers, or one (1) 500 amp, 600 volt breaker, also with a minimum 15 KAIC rating.

Q. How long does it take to install the TruePFC system?
TruePFC systems are customized to each installation site. Once the conduit and the breaker installation is complete, it takes about 4 hours to install the start-up the system.

Q. Does installation require an entire system shutdown?
No.

Q. Are there any daily start-up or shutdown requirements for the system?
No.

Q. How can I determine whether I need this technology?
If the load at the facility is not a constant load and the power factor is below the threshold required by the power company, then this technology would be a good fit. Contact TriPac Systems to discuss your specific needs.

Q. What happens if the system shuts down on its own? Will this shut down the power to my facility?
No. If the system were to have an unplanned loss of power, it will have no affect on the operation of the facility or on the incoming distribution system.

Q. What are the basic requirements of an electrical system for TruePFC to be installed?
3-phase, 480 volt power.

Q. Are there components in the system that wear out quickly?
No. This is a solid-state design with no moving parts.

Q. Does the system work with the European electrical system – 380/220 volt, 50 htz?
Yes.

Q. What is the average kW draw of the TruePFC system?
Negligible.
