Alternating Current To Find Single-phase Three-phase Amps when hp x 746 hp x 746 horsepower is known E x %Eff x pf 1.73 x E x %Eff x pf Amps when kW x 1000 kW x 1000 kilowatts are known E x pf 1.73 x E x pf Amps when kVA x 1000 kVA x 1000 kVA are known E 1.73 x E I x E x pf 1.73 x I x E x pf Kilowatts (kW) 1000 1000 I x E 1.73 x I x E Kilovolt-amp (kVA) 1000 1000 Horsepower- I x E x Eff x pf 1.73 x I x E x Eff x pf (Output) 746 746 kWh to kW kWh kWh (kW average) Time (hr) Time (hr)
Amps = PkW x 1000 = I PkW x 1000 = I
1 Megawatt VL-N 1.73 x VL-L
I = Amperes (current) E = Voltage - L-N (Single Phase) E = Voltage - L-L (Three Phase) %Eff. = Efficiency percent efficiency in decimals pf = Power Factor in decimals kVA = Kilovolt-Amphs (apparent power) kW = Kilowatts (power) hp = horsepower
1 OHM'S LAW
The Rate of the flow of the current is equal to Electromotive force divided by resistance
Electromotive Force = Volts = "E" Volts Amperes = Current = Amperes = "I" OHMS Resistance = OHMS = "R"
Series Circuit Parallel Circuit
A Series Ciruit is a circuit that has A Parallel Circuit is a circuit only one path through which the that has more than one path electrons may flow. through which the electrons Note: "T" stands for total may flow.
ET = E1 + E2 + E3 ET = E1 = E2 = E3 IT = I1 = I2 = I3 IT = I1 + I2 + I3 RT = R1 + R2 + R3 1 1 1 1 RT = R1 + R2 + R3
Note: For a parallel circuit having only two resistors, the following formula may be used.
R1 X R2 RT= R1 + R2
2 OHM'S LAW
A. When VOLTS and OHMS are Known:
Volts E Amps = or I = OHMS R
Example: Find the current of a 120 volt circuit with a Resistance of 60 OHMS. E 120 I = = = 2 Amps R60
B. When WATTS and VOLTS are known:
Watts P Ampers = or I = Volts E
Example: A 120 volt circuit has a 1440 watt load. Determine the current. P 1400 I = = = 12 Amps E 120
C. When OHMS and WATTS are known:
Watts P Ampers = or I = √ OHMS√ R
Example: A circuit consumes 625 watts through a 12.75 OHM resistor. Determine the current.
P 625 = 7 Amps I = √ R= √ 12.75 = √ 49
Notes: A. One electrical horsepower = 746 watts Electric motors are rated in horsepower
B. One Kilowatt = 1000 watts Generators are rated in Kilowatts 3 CT Metering Determination
Purpose: The purpose of the formulas below is to simplify the calculations for determining the current transformer (CT) needs for a project.
Definitions: kW = Estimated peak demand in kilowatts (P) V = Voltage at which the CT's are going to be applied Z = Impedance due to resistance, inductive reactance and capacitive reactance Formulas: Power = (CURRENT) (VOLTAGE) (1.73)
Power Current = (Voltage) (1.73)
kW kW kW I = = = (V) (√3) (V) (1.73) Z

General Directions for First Aid: While help is being summoned, do the following: 1) Minimize further injury – move victim if necessary for safety reasons 2) Control severe bleeding 3) Maintain an open airway and give Rescue Breathing or CPR if necessary 4) Treat for shock Urgent Care: BLEEDING-WOUNDS First Aid: 1) Direct Pressure and Elevation: Place dressing and apply direct pressure directly over the wound, then elevate above the level of the heart. Unless evidence of fracture. 2) Apply pressure bandage: Wrap bandage snugly over the dressing. 3) Pressure Point: If bleeding doesn’t stop after direct pressure, elevation, and pressure bandage. Compress the pressure point. Arm: Use the brachial artery – pushing the artery against the upper arm bone. Leg: Apply pressure on femoral artery – pushing it against the pelvic bone. 4) Nosebleed: To control a nosebleed, have the victim lean forward and pinch the nostrils together until the bleeding stops. POISONING Signals: Vomiting, heavy labored breathing, sudden onset of pain or illness, burns or odor around the lips or mount, unusual behavior. First Aid: If you think someone has been poisoned, call your poison control center or local emergency number and follow their directions. If conscious: Call Poison Control and try to identify the poison – be prepared to inform poison control of the type of poison, when incident occurred, victim’s age, symptoms, and how much poison may have been ingested, inhaled, absorbed, or injected. If unconscious or nauseous: 1) Position victim on side and monitor vital signs (pulse and breathing) 2) Call Poison Control and identify poison. 3) DO NOT give anything by month. SHOCK Signals: Cool, moist, pale, bluish skin, weak rapid pulse (over 100), nausea, rate of breathing increased, apathetic. First Aid: 1) Maintain open airway, have victim lie down 2) Maintain normal body temperature (98.6). If too hot, cool down, and if too cold, use blankets, over and under, to warm the victim.

BURNS
Signals: Small, thin (surface) burns or large, thin burns: redness, pain, and swelling. Deep burns: blisters, deep tissue destruction, charred appearance. First Aid: 1) Stop the burning – put out flames or remove the victim from the source of the burn. 2) Cool the burn – run or pour cool water on burn. Immerse if possible. Cool until pain is reduced. 3) Cover the burn – use dry, sterile dressing and bandage. 4) Keep victim as comfortable as possible from being chilled or over heated. Chemical burn – must be flushed with large amounts of water until EMS arrives. Electrical burn – make sure power is turned off before touching the victim.
ELECTRICAL SHOCK Signals: Unconsciousness, absence of breathing & pulse First Aid: 1) TURN OFF THE POWER SOURCE – Call EMS (DO NOT approach victim until power has been turned off). 2) DO NOT move a victim of electrical injury unless there is immediate danger. 3) Administer rescue breathing or CPR if necessary. 4) Treat for Shock. 5) Check for other injuries and monitor victim till medical help arrives.
HEAT EXHAUSTION/HEAT STROKE Signals: Heat Exhaustion: Pale clammy skin, profuse perspiration, weakness, nausea, and headache. Heat Stroke: Hot dry red skin, no perspiration, rapid & strong pulse. High body temperature (105°+) this is an immediate life threatening emergency. First Aid: 1) Get the victim out of the heat. 2) Loosen tight clothing or restrictive clothing. 3) Remove perspiration soaked clothing. 4) Apply cool, wet cloths to the skin. 5) Fan the victim. 6) If victim is conscious give cool water to drink. 7) Call for an ambulance if victim refuses water, vomits, or starts to lose consciousness.
