Question	Answer
? is/are fed into transformers to reduce distribution voltage to the utilization voltage specified by the health care facility.	Utility power
Prior to electrical power deregulation, what two service feeds would health care facilities often have?	One local or primary power grid and one non-local or secondary power grid
Due to the high cost of installing the infrastructure needed to provide redundant utility power sources, many design engineers are ? .	utilizing on-site power generation
What is the most cost-effective solution for switching between redundant power supplies in the event of a failure?	Manual transfer switches
true/false In a manual transfer utility design, in the event of a failure, a qualified person opens the primary feeder switch and closes the secondary feeder switch to provide normal utility power to the facility.	true
Primary and secondary utility distribution feeders are brought to the ? of a distribution voltage rated transfer switch.	line side
In a two service system that employs two distribution feeders and two utility transformers, each service is sized to handle ? of the health care facility.	the entire load
In a two-service system that employs two distribution feeders and two utility transformers, how many of the transformers’ secondary sides are provided with a disconnect?	2
Double-ended switchgear electrically divides the load into two distinct sections through the use of ? .	tie-breakers
During normal operation of double-ended switchgear, the mains from both utility transformers are ? , and the tie breaker between the two ends of the switchgear is ? .	closed/open
During a utility power outage of the primary service, the main switch on the primary should be opened and the tie breaker in the double-ended switchgear should be closed. The secondary service will now carry how much of the health care facility load?	100%
A qualified person should open the main switch of the utility transformer experiencing the outage ? closing the tie breaker to avoid backfeeding the grid with the entire energy of the second energized service.	before
To avoid the potential catastrophe of the main and tie breakers being closed at the same time, equipment manufacturers utilize a ? system.	keying this system uses a keys that are captured by the system when a switch is closed. this system requires a key to open and a a key to close both the main switch and the tie-breaker.
How many keys exist in the keying system used to prevent back feeding of double-ended switchgear?	2
NFPA 99 and NFPA 110 require certain loads in health care facilities, namely elements of the essential electrical system, to be brought online within ? of a power outage.	10 seconds
What must be done for current from different utility feeders to occupy the same service bus without issue?	Phase synchronization must be done.
true/false Opening one device on a loop distribution system will adequately deenergize the distribution loop.	false
NFPA 99 and NFPA 110 require health care facilities to have on-site power generation capacity sized to take on several types of loads. Which type of loads are covered by these codes?	Critical systems, Defined equipment and Life safety systems
true/false On-site generation is required to have the capacity to assume the entire load of the health care facility.	false
true/false NFPA 99 and NFPA 110 require on-site generation to assume the life safety, critical, and defined equipment loads within 10 seconds after a normal power outage.	false
In the event of a generator overload, NFPA 99 and NFPA 70 allow generating systems to ? .	shed the equipment load
When multiple generators are attached to a common bus, ? is used to ensure each generator is in phase with the others.	paralleling switchgear
What is the minimum number of generators used in parallel?	2
What concerns should be considered when installing diesel and natural gas generators?	Heat distribution, Mounting requirements and Starting systems
Generator fuel is often stored in large underground tanks. This fuel is typically pumped into smaller tanks called ? that are located near the generators.	day tanks or transfer tanks
Day tanks use ? to alert personnel that a fuel pump is malfunctioning and is no longer pumping fuel from the storage tank.	low-level alarm limit sensors
Day tanks use ? to activate the main storage fuel pump to fill the day tank.	low-level limit sensors
Day tanks use ? to shut off the main tank pumping system when the tank is full.	high-level limit sensors
If the fuel pump or level sensors are malfunctioning, day tanks use ? to signal personnel that the tank is about to overflow.	high-level alarm sensors
Approximately ? of the energy released by burning fuel is converted into electrical energy.	33%
true/false A malfunctioning exhaust gas heat exchanger will quickly cause a generator to overheat and go offline.	false it will not impact the performance of the generator due to the malfunction of an exhaust gas heat exchanger
For generators installed in an enclosed environment, ? are used to move coolant to and from remotely located radiators.	electric pumps
true/false Coolant degrades over time, which can cause scale deposits to build up on the radiator core, limiting the core’s ability to cool the coolant.	true coolant degrades over time, which can cause scale deposits to build up on the radiator core, severely limiting the core's ability to exchange heat with the surrounding air.
What is the most likely cause for a generator start up failure?	Undercharged batteries the most common cause for starting failure lies with the generator starter motor batteries and the associated battery charging equipment.
In cold climates, generators are fitted with ? to keep the engine blocks at the optimum temperature for quick starting.	block heaters
Typically, generator starter motor batteries are lead-acid storage batteries. However, some systems use ? .	nickel cadmium batteries
NFPA 99 requires generator accessories such as battery charging equipment to be installed on the ? branch of the essential electrical system.	life safety
When batteries have reached the end of life as determined by the manufacturer, or when they are not testing to manufacturer’s specifications, they should be ? .	replaced promptly
In the past, during high demand periods, power companies would offer health care facilities with self-generation capabilities a reduction in rates if the facility would generate power during these high demand periods. This practice is known as ? .	peak shaving this was a double win for facilities, which ended up using less utility power during these high demand periods and paying reduced rates for utility power.
What should be considered before a health care facility enters into a peak shaving agreement?	The cost of fuel, The cost of generator wear and tear, The price of utility power
The United States Environmental Protection Agency (EPA) has expressed concern about peak shaving because of ? .	diesel exhaust pollution
Because self-generation for non-essential loads is not required to be online within 10 seconds after an outage, ? have become an attractive alternative to reciprocating engines.	gas turbines
Turbine engines have much less vibration than reciprocating engines because ? .	their shaft rotation is continuous
Gas turbine generators have ? power to weight ratio than diesel generators.	a lower
Gas turbine generators can be a good choice for on-site power generation because ? .	they are dual-fuel capable, they are quieter, they have lower emissions
