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 >>
Now available for rent from Protec Equipment Resources, the EA Technology CableData Collector identifies and reports Partial Discharge (PD) activity in live Medium and High Voltage (MV/HV) cable networks, allowing for early identification, and reducing the need for disruptive maintenance outages by uncovering high risk areas in time for repairs and replacements.READ MORE >>
The effective and efficient operation of a power grid is largely dependent on the relay scheme. The importance of this critical electrical component makes it essential to regularly test its health status using high-grade electrical test equipment.READ MORE >>
