These two transformer tests are performed to find the parameters of equivalent circuit of transformer and losses of the transformer. Open circuit test or no load test on a transformer is performed to determine 'no load loss (core loss)' and 'no load current I0'. Hence, it is seen that open circuit test gives core losses of transformer and shunt parameters of the equivalent circuit. The connection diagram for short circuit test or impedance test on transformer is as shown in the figure below. Therefore, equivalent reactance of transformer can be calculated from the formula  Zeq2 = Req2 + Xeq2. Hence, it is seen that the short circuit test gives copper losses of transformer and approximate equivalent resistance and reactance of the transformer. From the above transformer tests, it can be seen that Cu loss of a transformer depends on current, and iron loss depends on voltage.

Every FGWilson Generator is covered by comprehensive warranty cover against defects in material and workmanship within the warranty period. The Warranty period of a genset depends on the application of that genset and the hours of usage, a prime power genset has a warranty of 12 months from the date of start-up, a standby genset's warranty last for 24 months as long as it runs no more than 500 hours in each of the 2 years.
The first thing to do when something has failed is contact FGW Latca, it may as simple as a blown fuse or a more complicated problem, but discussing it with us may resolve the problem before time and money is spent. Do not dispose of any failed parts, hold on to them because they may be requested to be returned to the manufacturer for inspection - this is especially important for high value items.
After the claim is submitted to the manufacturer there are targets and guidelines which will ensure a quick response. As a final step before posting your comment, enter the letters and numbers you see in the image below. This is a collection of pictures taken of FG Wilson Generators at work in Latin America and the Caribbean. Constant losses are those losses which are considered to remain constant over normal working range of induction motor.


Mechanical losses occur at the bearing and brush friction loss occurs in wound rotor induction motor.
A part of this power input is used to supply stator losses which are stator iron loss and stator copper loss.
Now, the rotor has to convert this rotor input into mechanical energy but this complete input cannot be converted into mechanical output as it has to supply rotor losses. Now this mechanical power developed is given to the load by the shaft but there occur some mechanical losses like friction and windage losses. At Tekserve, Michael explained to me that the Mac Pro is designed around a workstation graphics model with dual GPUs, PCIe-based flash storage, 6 high-performance Thunderbolt 2 ports, new-generation Xeon processors, ultrafast memory, and it supports 4K video. I had the opportunity to take a deeper look behind this small, powerful and yes very quiet computer and found out that the new-generation Intel Xeon E5 Processor is available with 4, 6, 8, or 12 cores of processing power.

Open circuit test and short circuit test on transformer are very economical and convenient because they are performed without actually loading of the transformer. A wattmeter (W), ammeter (A) and voltmeter (V) are connected to the LV winding as shown in the figure.
Though, a voltmeter is connected, HV winding can be treated as open circuit as the current through the voltmeter is negligibly small. The LV side of transformer is short circuited and wattmeter (W), voltmere (V) and ammeter (A) are connected on the HV side of the transformer.
2 Grounding Electrode Conductor and Bonding Jumper Connection to Grounding ElectrodeThis section has been revised to make it clear that when a bolt and nut is used to attach a grounding electrode compression connector under fire proofed structural metal it does not have to be accessible.
To ensure the customer benefits from this cover it is important that the complete FG Wilson warranty process is understood. We recommend that you always use quality diesel fuel, quality lubricating oil to manufacturer's specification, service your genset at the recommended intervals and always use OEM FGW filters.
If it is deemed a warranty failure then the parts must be purchased and the repair completed.
If the failure on the Delphi fuel injection equipment is deemed to be warrantable the parts usually will be repaired or replaced by the Delphi dealer free of charge. When the manufacturer receives the claim and accepts it, these costs will be reimbursed according to alloted labor rates and repair times. So basically I am asking you to help us help you, the quicker that failures are reported and submitted the better chance there is of a successful claim process. The fixed losses can be easily obtained by performing no-load test on the three phase induction motor. The remaining power i.e ( input electrical power a€“ stator losses ) are supplied to rotor as rotor input. As explained earlier the rotor losses are of two types rotor iron loss and rotor copper loss.
Guyot Bernardo Arocho Jr from BJ’s Technology News Blog recently paid us a visit to check out the new Mac Pro in person, interview our own Michael Truskowski, and review the new workstation from Apple. The Mac Pro is engineered with a single and larger fan that pulls air upward through the bottom intake. Now, applied voltage is slowly increased from zero to normal rated value of the LV side with the help of a variac. Voltage is applied to the HV side and increased from the zero until the ammeter reading equals the rated current. Reinforcing bars shall be permitted to be bonded together by the usual steel tie wires or other effective.NEW sentence added.


Every genset manual pack has a warranty section near the back, in this section the general warranty statement is laid out detailing FG Wilson's responsibility, the User's responsibility and the warranty limitations. This is even more important during the warranty period of the genset as the warranty may be affected if the customer does not follow FG Wilson reccommendations. The next step is to fill in a warranty claim form, this form needs the genset serial numbers, dates of start-up and failure, hours run and concise information regarding the failure etc. Since by laminating the core, area decreases and hence resistance increases, which results in decrease in eddy currents. As the load changes, the current flowing in rotor and stator winding also changes and hence these losses also changes. Since the iron loss depends upon the rotor frequency, which is very small when the rotor rotates, so it is usually neglected. Therefore the net output power developed at the shaft, which is finally given to the load is Pout. As air passes vertically through the center of the device, it absorbs heat and carries it out the top of the device. When the applied voltage reaches to the rated value of the LV winding, readings from all the three instruments are taken. But as described above, short circuit current is so small that these copper losses can be neglected. The size of the conductor used to connect the IBT to the power service grounding electrode system must not be smaller than No. In this warranty statement, references are made to the Warranty Registration Form and the Pre-Delivery inspection sheet, these are included in triplicate in the manual pack along with the Commissioning Sheet. For example, it makes it very difficult for us to make a case for a failed engine when there is no service history evident, non OEM filters have been used and oil or diesel fuel is of questionable quality - considering the value of the genset the outlay for a planned maintenance schedule using quality parts and fluids is a small price to pay for peace of mind and will prolong the life of the genset. This form should be submitted to LATCA as soon as possible after the failure occurs as we are time-constrained in claim submittal to the manufacturer i.e. So when a genset is received directly by a customer or by a dealer, they should fill these forms in and return them to us in a timely manner this helps to identify the genset at a later date should a claim be made. The copper losses are obtained by performing blocked rotor test on three phase induction motor.The main function of induction motor is to convert an electrical power into mechanical power. If damage is evident on a recently delivered genset then the Pre-Delivery Inspection sheet should be used to submit this information within 72 hours of it's receipt. Photographs of major engine and alternator failures are required, we may also request that the failed part be returned so it is important to hold any failed parts for six months.
The frequency of stator is always supply frequency, f and the frequency of rotor is slip times the supply frequency, (sf) which is always less than the stator frequency.
During this conversion of electrical energy into mechanical energy the power flows through different stages. For stator frequency of 50 Hz, rotor frequency is about 1.5 Hz because under normal running condition slip is of the order of 3 %. Hence the rotor core loss is very small as compared to stator core loss and is usually neglected in running conditions.
