MGM Transformer Company Why do transformers hum? Transformer noise is caused by a phenomenon which causes a piece of magnetic sheet steel to extend itself when magnetized. When the magnetization is taken away, it goes back to its original condition. This phenomenon is scientifically referred to as magnetostriction.

What's Causing Rattling In Pipes? Q: Our two-story home has f4.5 bathrooms, which all seem to have a common cold water pipe that runs through a particular wall and ceiling. In four of the baths, when the toilet is flushed the water cutoff causes the pipes to vibrate very loudly somewhere in the wall or ceiling. Turning off the cold water faucet at the sink also causes a vibration. We've had three different plumbers out.

Symptoms of Common Hydraulic Problems and Their Root Causes Abnormal noise in hydraulic systems is often caused by aeration or cavitation. Aeration occurs when air contaminates the hydraulic fluid. Air in the hydraulic fluid makes an alarming banging or knocking noise when it compresses and decompresses, as it circulates through the system.

Typical Failures in Three-Phase Stator Windings They are shown here to help you identify the causes of failure, so that, where possible, you may take preventive measures. Compare the new stator winding (here) with the failed windings pictured below. Winding single-phased (wye-connected) A single-phased winding failure is the result of an open in one phase of the power supply to the motor. The open is usually caused by a blown fuse, an open contactor, a broken power line or bad connections. Winding shorted phase-to-phase. This type of insulation failure is typically caused by contaminants, abrasion, vibration or voltage surge.

- Resonators and mufflers: excessive rust, damage, or holes can cause excessive noise and rattles. Exhaust pipes, hangers, clamps, and brackets: excessive rust, broken bolts or worn parts can cause the parts to hang dangerously low, resulting in a hazard for the people driving behind you.

Understanding coil whine Has anyone researched coil whine to understand exactly what causes it? I had previously concluded that coil whine was directly related to voltage. I Have an Abit IN9-32x Max which I ran two cpu's on. One was an e6300 and the other an 8400.

Why Do My Pipes Hum After I Flush the Toilet? Humming pipes are sometimes an indicator that water pressure is too high. In homes where the water supply is from a well, the homeowner has the option of lowering pressure at the pump and pressure tank. In homes using a municipal supply, owners should consider contacting a plumber to install a pressure reducing valve.

What causes a humming/growling noise in driver's front wheel area and it increases/higher pitch with speed? I noticed recently that there is a humming or growling noise coming from the driver's front wheel area that increases(higher pitch) with speed. It makes the noise when slowing down also. There is no noise at idle or parking lot speed. The noise started as slightly audible and has increased to being heard...

Why Is My Air Conditioning System Making a Buzzing Noise? A buzzing sound coming from your air conditioning system can have a number of different causes. It is possible that this is an electrical problem. It may be the contactor in your system, which feeds the start capacitor. If the contact points are dirty or burnt, you may hear a buzzing, chattering sound coming from your system.

Other than ground loop sources for humming If the noise is lower, the AC service may be the cause. Magnetic fields from transformers can cause humming. Mains transformers typically cause an AC magnetic field around them. This magnetic field can be copled to wiring, electronics or signal transformers and cause humming.

Power Transformer Problems 1 Identify the terminals of the power transformer. 2  Using an ohmmeter, measure the resistance of the primary (usually Black-Black wires) and the resistance of both leads to the chassis. 3  The primary should be under 1K ohms. 4  If it is not, the transformer is dead. If it is more than that, the transformer is bad. 2  Measure the resistance from either end of the winding to chassis. 3  If it is less than 100K ohms, unsolder the leads and measure again. 4  If this reading is less than 100K ohms, the transformer is bad.

Troubleshooting Electrical Problems Static interference and harmonic distortion are electrical disturbances caused, for example, by air conditioners, vacuum cleaners, hair dryers and cordless phones. A leading cause of electrical trouble for home computers, they can also create serious problems for stereo, radio, security and phone systems.

- For those of you who are wondering what noise is, I like to define it as any sound reproduced by the loudspeakers that is not present in the source material. Alternator whine, amp swizzle, ignition noise, turn on thump, and system noise are just a few examples that come to mind. Replace with silicone resistor plug wires. 2  If the noise is a buzzing sound, the problem is usually associated with the points, distributor, or coil. 3  Try replacing the condenser on both the coil and points. 4  Make sure all plug wires are seated properly in the distributor cap.

Refrigerator making Humming Noise Sound coming from inside the fridge. The evaporation motor inside the fridge is supposed to get rid of excess moisture that could form ice inside your refrigerator. If the sound becomes louder when you open the fridge, then your evaporation motor is probably broken.

- Eaton Corporation 1.800.356.5794 www.powerware.com 3 A technical view of harmonics Harmonics are currents or voltages with frequencies that are integer multiples of the fundamental power frequency. If the fundamental power frequency is 60 Hz, then the 2 nd harmonic is 120 Hz, the 3 rd is 180 Hz, etc. (see Figure 1). When harmonic frequencies are prevalent, electrical power panels and transformers become mechanically resonant to the magnetic fields generated by higher frequency harmonics. When this happens, the power panel or transformer vibrates and emits a buzzing sound for the different harmonic frequencies.

How to Eliminate Engine Noise How to Eliminate Engine Noise. Engine/Alternator noise sounds like a high pitch whining that gets louder and higher in pitch as you press on the gas pedal. This noise indicates that the system either has a bad ground, defective head unit, defective amplifier, bad RCA cables, improper installation, or a problem in the vehicle’s charging system. Follow the steps below in order to pinpoint the cause of engine noise and reduce or eliminate the problem.

Phantom calls The other cause of ghost calls is a fax duet line or if a fax is being recieved, If a fax is being recieved the T-Hub will answer the call thinking its a voice call rather than a data call (FAX). I would recommend to call T-Hub support on 1300136841 as they should have access to the systems to check all this.

- Clunking, whining, buzzing, or humming can all be indicators of transmission problems. Components of an engine or transmission cannot make noise unless they are in movement. Even if a noise goes away when the vehicle reaches a particular speed it does not mean that the problem goes away.

Many Causes Of Groaning Noise Visible pipes that might be loose can be secured with pipe strap or small brackets, both sold at home centers and hardware stores. •Finally, waterlogged air chambers or water-hammer arresters can groan as well as make knocking and banging noises. Noise usually occurs when faucets or fixtures are shut off. The remedy is to drain the water out of the system and let the chambers refill with air, which acts as a shock absorber for plumbing pipes.
