UPS's
What does UPS stand for?
What is uninterruptable power supply
ITE centers are common locations that require higher tier levels of redundancy. What does ITE stand for?
What is Information Technology Equipment
A typical automatic transfer switch has how many incoming and how many outgoing line voltage connections?
What are two incoming (backup and normal source) and one outgoing (to critical load)
A fuel cell creates electricity with this process
What is an electrochemical reaction
Factory acceptance testing for equipment is conducted here
Where is the factory; before the equipment is even shipped and installed onsite
What is the most common type of backup power source for a UPS?
What are batteries
This tier is the most common and least expensive for an owner to install
What is tier one
The three categories of generators covered in the Distributed Generation Course are Continuous, Prime, and this category which includes most generators we install as inside electricians.
What is standby
The three parts to a fuel cell are an anode, cathode, and this part
What is an electrolyte membrane
This process is mostly completed after the installation of equipment in a facility
What is the commissioning process
A UPS does this in addition to provide backup power
What is filter/clean the incoming utility power
What article in the NEC covers Information Technology Equipment (ITE)?
What is article 645
This piece of equipment is typically what tells a backup generator to start in the case of a normal power failure.
What is an Automatic Transfer Switch (ATS)
This is the typical DC voltage that a fuel cell produces
What is 48 volts
A power system installed with this tier level will experience the least amount of impact on a critical load when troubleshooting, or performing maintenance.
What is tier 4
This type of UPS is the most common, least expensive, and is commonly used for individual personal computers in office or home settings.
What is a standby UPS
This is defined as "an element of the electrical distribution system that at some point will cause downtime, if a means to bypass it is not developed in the system."
What is a single point of failure
This piece of equipment typically is installed between the UPS and the critical load (such as network switches or computers)
What is a power distribution unit (PDU)
In this part of a fuel cell the hydrogen molecules are split into protons and electrons.
What is the anode
Surge protective devices (SPD's) are installed to protect against this power quality issue.
What are voltage transients
This type of a UPS uses a DC motor or a flywheel as a means of backup power instead of batteries
This type of switch in an ITE center requires a two-step operation. (Break glass, and then push button; as an example)
This type of switch is similar to an automatic transfer switch but it uses electronics in its switching function which makes it react faster than an ATS.
What is a static transfer switch (STS)
All fuel cells require these two physical connections to them so they can do their job
What are fuel source piping (such as hydrogen) and an electrical load connection (such as a building or car)
This testing equipment would be used to troubleshoot an intermittent fault that is happening a couple of times per week
