37.5 amps converted in watts?
To convert amps into watts a voltage is needed. Watts = Amps x Volts.
Convert .01 amps to mili amps?
1 Amps = 1000 miliamps 0.01 Amps = X x= 0.01 X 1000 = 10 miliamps
Convert 15 amps 415v to kw?
15 amps X 415volts = 6225watts or 6.225Kw
Convert 140va at 240v equals amps?
0.583333333333
What is 0.011 in converting watts to amperes?
To convert watts to amps a voltage value must be given. Amps = Watts/Volts. Amps = .011/Volts.
What is purpose of ten delta test on transformer?
To ascertain the life of insulation, or effectiveness of the insulation (HV to LV, HV to earth and LV to earth) of the transformer
What is a difference between hv motor and lv motor?
the motor having voltage rating above 480 volt is hv motors and motor having rating below 480 volt is lv motors. generally motor above 185 kw is hv or mv motor and motor below 185 kw is lv motor.
What is the meaning of 32Yd1 on a transformer?
This is 3 Nos Two Winding Transformers put together to form of Three Phase transformer, HV is Star Connected & LV is Delta Connected in the LV phase is leading by 30 Degree with respect to HV phase
What is the difference between Dyn-11 and Ynd-11?
Winding connection designations High Voltage Always capital letters Delta - D Star - S Interconnected star - Z Neutral brought out - N Low voltage Always small letters Delta - d Star - s Interconnected star - z Neutral brought out - n Phase displacement Phase rotation is always anti-clockwise. (international adopted convention) Use the hour indicator as the indicating phase displacement angle. Because there are 12 hours on a clock, and a circle consists out of 360°, each hour represents 30°. Thus 1 = 30°, 2 = 60°, 3 = 90°, 6 = 180° and 12 = 0° or 360°. The minute hand is set on 12 o'clock and replaces the line to neutral voltage (sometimes imaginary) of the HV winding. This position is always the reference point. Because rotation is anti-clockwise, 1 = 30° lagging (LV lags HV with 30°)and 11 = 330° lagging or 30° leading (LV leads HV with 30°) To summarise: Dd0 Delta connected HV winding, delta connected LV winding, no phase shift between HV and LV. Dyn11 Delta connected HV winding, star connected LV winding with neutral brought out, LV is leading HV with 30° YNd5 Star connected HV winding with neutral brought out, delta connected LV winding, LV lags HV with 150° " So there is no specification of Dy11.. it will be Dyn11 "
Why tappings are always provided in HV winding of power transformers?
in hv side, current will be less; so if we vary the rheostate, than thetre is less arcing with respect to lv side, so we always put the tap changer in hv side.
How do you convert 500VA into amps?
4.3 amps
What is the meaning of DYN 11 on a transformer nameplate?
What does Dd0, Dyn11, YNd5 etc. mean?First symbol/symbols, capital letters: HV winding connection.Second symbol/symbols, small letters: LV winding connection.Third symbol, number: Phase displacement expressed as the clock hour number.Winding connection designationsHigh Voltage Always capital lettersDelta - DStar - SInterconnected star - ZNeutral brought out - NLow voltage Always small lettersDelta - dStar - sInterconnected star - zNeutral brought out - nPhase displacementPhase rotation is always anti-clockwise.

Convert 18 VDC to AC amps?
Amps is amps be it DC or AC.
How do you carry short circuit test on power transformer?
For carrying Short Circuit Test on Power Transformer Do the following: 1] Isolate the Power Transformer from service. 2] Remove HV/LV Jumps and Disconnect Neutral from Earth/Ground. 3] Short LV Phases by Cu/Al plate which could withstand short circuit current and connect these short circuited terminals to Neutral 4] Energise HV side by LV supply (440 3ph Supply) with OLTC tap position on Normal. 5] Measure Current in Neutral, LV line voltages, HV Volatage and HV Line Currents on various OLTC Tap position. Analysis: If Neutral current is near to zero transformer windings are OK If Neutral current is higher or equal to Line current between LV Phase one of the winding is Open.
How do convert watts to amps?
Watts are the product of amps x volts.

What is the formula to convert amps to volts?
Amps and volts are two separate parts of power measurement and do not convert into each other. Multiplying amps times volts will give you the measurement of wattage.
