How do you calculate LT?

How do you calculate LT?

Calculate the sum of your heart rate at 10 minutes and your heart rate at 30 minutes and divide by two. That’s your LT heart rate.

How do you calculate current HV?

Using the aforementioned formula, let’s confirm this rating:

1. Primary Voltages or High Voltages (H.V) is 11000 volts.
2. Primary Current (current on High Voltage side) is 5.25 amps.
3. KVA = (√3. V x I) /1000= (1.732 × 11000 × 5.25)/1000=100 KVA.

How do you calculate 11kV amps?

Take a 11kV/415v, 500KVA distribution system. Then maximum current on HV side = 500/{sqrt(3) * 11} = 26.24 A. maximum current on LV side = 500/{sqrt(3) * 0.415} = 695.6 A.

How do you find the current on the primary side of a transformer?

If for some reason you need a larger transformer to operate appliances, you still divide the wattage by the voltage to find the current. For a 120-volt primary, 2000-watt transformer, divide 2000 by 120 for the current (2000 Watts /120 volts =16.67 amps). For a 240-volt, 3000-watt transformer, the current is 12.5 amps.

How many amps is a 2500 kVA transformer?

What is the formula for efficiency?

Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output (“product”) produced per the amount C (“cost”) of resources consumed.

How many amps is 70 kVA?

kVA to amperes, table for conversion, equivalence, transformation (3F, 220Volt) :

How many kVA are: Ampere Equivalence
40 kVA 104.97 Amp.
50 kVA 131.22 Amp.
60 kVA 157.46 Amp.
70 kVA 183.70 Amp.

What is the formula for transformer?

Vp=−NpΔΦΔt V p = − N p Δ Φ Δ t . This is known as the transformer equation, and it simply states that the ratio of the secondary to primary voltages in a transformer equals the ratio of the number of loops in their coils.

What is 1 kVA in amps?

1,000 Volt-Amperes
1 kVA is a frequently used unit; it represents 1,000 Volt-Amperes….kVA To Amps Calculator (With Table)

kVA (Apparent Power) Voltage (220 V) Amperage (A)
How many amps is 1 kVA? 220 V 4.55 Amps
How many amps is 5 kVA? 220 V 22.73 Amps

How to calculate the HT / Lt current Formula?

VA is LT volts multiplied by LT amps. Let us take a 1200 VA transformer where the primary voltage is 120 Volts and the secondary is 12 Volts. Then- Another way of doing this is to look at the voltage ratio, 120 to 12 volts in this case. That is a ration of 10:1. Transformers are rated in volt amps, VA.

What does HT stand for in a current?

University of Hyderabad. HT means high tension or high voltage, where in a small current is used with a very high voltage(for creating plasma).

How to calculate the size of a HT cable?

In case of LV system cable can be selected on the basis of its current carrying capacity and voltage drop but in case of MV/HV system cable short circuit capacity is an important/deciding factor. So in case of HT motor, the cable short circuit capacity alone is enough to determine the cable size as rest two parameters will automatically follow.

How to calculate the current through a conductor?

Ohm’s Law Current Calculator. Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference across the two points, and inversely proportional to the resistance between them. Here we can calculate Ohm’s Law for Current.
