HJ Arnett Industries- Who are we? • Located in Portland, OR- Established in 1971 • Began with ideas from lineman for tools needed in the field and began manufacturing to fill those needs • Full Dielectric Testing Lab- Rubber goods, Hot Line Tools, Boom Trucks • Revenue Protection Consulting Group- Assist with investigation and reclamation of revenue lost from illegal taps, tampering and fraud • Product Manufacturer- Proprietary goods used for revenue protection, power quality and fault locating investigations
Power Quality- Sources of Problems • Harmonic distortionContinuous or sporadic distortions of the 60-hertz (Hz) voltage sine waveform, usually caused by microprocessor based loads in the building such as computer power supplies, lighting ballasts, and electronic adjustable speed drives. Harmonics can also be transmitted from an energy user down the block. These can cause telecommunications or computer interference; overheating in motors, transformers, or neutral conductors; decreased motor performance; deterioration of power-factor correction capacitors; or erratic operation of breakers, fuses, and relays. • Interruption, momentary A very short loss of utility power that lasts up to 2 seconds, usually caused by the utility switching operations to isolate a nearby electrical problem. • Interruption, temporaryA loss of utility power lasting from 2 seconds to 2 minutes, caused by a nearby short circuit due to something like animals, wet insulators, or accidents. Corrected by automated utility switching.
Power Quality- Sources of Problems • Long-term outageA loss of utility power lasting more than 2 minutes due to major local, area, or regional electrical events. • NoiseSporadic voltage changes consisting of frequencies higher than the normal 60-Hz power frequency due to any number of causes, including arc welders, loose wiring, and nearby radio and TV transmitters. • SagA short-term decrease in voltage lasting anywhere from milliseconds up to a few seconds. Sags starve a machine of the electricity it needs to function, causing computer crashes or equipment lock-ups. Usually caused by equipment start-up-such as elevators, heating and air-conditioning equipment, compressors, and copy machines-or nearby short circuits on the utility system.
Power Quality- Sources of Problems • SpikeA very brief (nanoseconds to milliseconds) change in voltage ranging from tens to thousands of volts. Can be produced by utility and customer equipment operations, nearby lightning strikes, falling tree limbs on power lines, and even static discharges. • SurgeA short-term increase in voltage, lasting up to a few seconds. They are due either to customer equipment operation, such as air conditioners or motors switching on and off, or to utility activities, such as capacitor switching. • Transient A sudden momentary change in voltage. Also called a spike. • UndervoltageA decrease in voltage lasting longer than a few seconds. Usually due to undersized wiring at the facility but can also be caused by overloaded utility circuits and result in brownouts.
Power Quality- Why do customers call? What are we really looking for? • Lights dim when several appliances are in use or as they are turned on. (hair dryers, toaster oven, TV, stereo, computer) • Lights work, but appliances do not work properly (toaster oven doesn’t heat, hair dryer runs slow, etc.) • We are looking for service problems…on the Utility Side (examples: transformer to meter cable faults/connections) or Customers Side (examples: internal electrical circuit, faulty wiring, circuit breaker/fuse).
Power Quality Testers • The Super Beast and Mega Beast are conductor testers used to apply an Amp load on 120/240 volt service to determine if there is an conductor or neutral problem. • Eliminates the need for homeowner being present during testing. One utility employee can perform a test at the meter socket and immediately determine the source of problems.
The following tutorial is a factory simulated model and results for individual utilities may vary. Always wear proper safety equipment when operating the Mega Beast. Make sure all connections are secure. First things First
Remove the KWH meter and inspect base for loose connections or other issues. With the Mega Beast 100 Amp breaker in the off position (de-energized), hook up the alligator clips as shown. First place the Green Neutral, then place Black on left, Red on Right. Getting Started
When the alligator clips are secured in place, flip the 100 Amp breaker to “ON” and the voltages between each conductor and the neutral will be displayed on the digital meters. The 112 V shown to the right should be 120V +/- 5%. Remember the displayed pictures are factory simulations and not indicative of actual field voltages. Voltage
Turn the switch to the left and start by applying 20 Amps by turning on one of the four toggle switches (no order necessary). You may add an additional 20 Amp load as needed, up to 80 Amps. In the following picture there is no problem with the left meter only dropping 1V. Applying a load to the left conductor
This photo shows a partially open left conductor with the left meter dipping significantly and the right meter only dropping a volt or two. Applying a load to the left conductor
Here we have a fully open left conductor. The left meter goes blank and the right meter remains close to the original voltage. Applying a load to the left conductor
The photo on the right shows us a partially open neutral. With the load applied to the left, the left meter decreases significantly and the right meter increases. If you move the switch to the right you will see the voltages reversed. Applying a load to the left conductor
A full open neutral is shown here to the right. Whether you have the load applied to the left or right conductor the meter readings will be the same with one close to 240V and the other blank. A full open neutral
The right meter drops one or two volts and the left meter doesn’t drop or drops very little. The more load you apply the more the voltage readings will decrease. If no major change in voltage then the utility side of the meter is OK. Applying a load to the right conductor
This photo shows a partially open right conductor with the right meter dipping significantly and the left meter only dropping a volt or two. Applying a load to the right conductor
Here we have a fully open right conductor. The right meter goes blank and the left meter remains close to the original voltage. Applying a load to the right conductor
The photo on the right shows us a partially open neutral. With the load applied to the right, the right meter decreases significantly and the left meter increases. If you move the switch to the left you will see the voltages reversed. Applying a load to the right conductor
Remember, if you take the Mega Beast out in the field and haven’t used it before or it has been awhile, please read the field instruction guide on the back panel for a quick review. Referencing the field guide on back panel
Finishing Note • Please remember to wear your safety clothing and rubber protective gear when using the Mega Beast. • The Mega Beast is for use on 120V service only. • If you have any questions or need any assistance using the Mega Beast, please give us a call at 1-800-684-9844.
