The ﬁrst Vanguard product was a computerized circuit breaker analyzer, which became the forerunner of an entire series of circuit breaker test equipment. Since then, the Vanguard product line has expanded to include microcomputer-based, precision micro-ohmmeters, single and three phase transformer winding turns ratio testers, transformer winding-resistance meters, mega-ohm resistance meters, and a variety of other electrical utility maintenance support products.READ MORE >>
The Dranetz HDPQ Xplorer Power Quality Analyzer has what it takes when it comes to energy monitoring capabilities, for both long and short duration surveys.READ MORE >>
Ohmmeters are an electronic device that measure electrical resistance, and come with different levels of sensitivity. Some are designed to measure low-resistance materials, while others measure higher resistance. The higher resistance the material has, the less current will pass through it.
An ohmmeter is typically not used to measure resistance across an entire circuit, but rather through various parts of the circuit, although it can be used to test that a circuit is not broken.READ MORE >>
The Raytech CT-T1 is a microprocessor-based Current Transformer Tester that measures CT excitation current, ratio, and winding polarity tests, all without having to switch the leads during testing.
This CT Tester is precision-made, fully automatic, portable, and built to stand up to the harsh environments of field testing.READ MORE >>
The Bierer PD800W Cordless Phasing Tester accurately and easily operates in multiple applications including:
A unique tester, the Bierer PD800W is an all-in-one kit for three-phase secondary systems, capacitive test points, URD systems and overhead and transmission/substation systems. The tester operates like a conventional phasing tester, but does not require an interconnecting cable or extension resistors.READ MORE >>
Distortion, harmonics and variations in voltage can cause a variety of problems in electrical lines, resulting in wasted power, accelerated deterioration of equipment, and high levels of electromagnetic interference, causing an electrical system to become unstable and eventually breakdown.READ MORE >>
