I see techs in the field get the most frustrated when they have a low-voltage short they can’t seem to locate. The challenge techs face with low voltage diagnosis is a combination of poor process and some root misunderstanding about what they are looking for.
It is designed and configured to take and capture highly accurate voltage measurements from the spinning shafts of motors. It comes with a conductive microfiber tipped probe for shaft contact, a probe holder with magnetic base, and a compact carrying case.
The U.S. Department of Energy’s (DOE’s) Building Technologies Office is seeking graduate students interested in exploring energy systems of buildings and how building assets or functions can integrate and transact with the energy grid supplying the building’s energy. The deadline for applying is Nov. 15, at 11:59 p.m. EST.
The U.S. Department of Energy (DOE) is matching a $2.25 million Clean Energy Fund grant from the Washington Department of Commerce to research, develop, and demonstrate the technologies needed to create smart buildings, campuses, and cities to better manage energy usage.
The NCVT-3 Non-Contact Voltage Tester with Flashlight identifies ac voltage in cables, cords, circuit breakers, outlets, wires, doorbells, thermostats, low-voltage lighting systems, irrigation systems, and more.
Compressor overheating is usually caused from high compression ratios. High compression ratios can be caused from a combination of high condensing pressures (temperatures) and low suction (evaporating) pressures.
Today more and more systems are incorporating microprocessor controllers into their design. Troubleshooting the operation of these controllers can be a little tricky at times, but if broken down into sections it can be easier to handle.
