For testing high voltage electrical equipment, AC dielectric test equipment can provide accurate indications of leakage current, in addition to valuable insight regarding the insulating characteristics of electrical apparatus. Using equipment such as an AC high potential test set can help in rapid detection of impending insulation failures and provide assurance that equipment is safe to operate.READ MORE >>
Tracing the path of installed wiring using conventional methods like continuity tests can be a hassle because you need to power down the system. You can use a circuit tracer instead to trace wires even when the cables are energized. This saves you time and effort troubleshooting cable problems in electrical systems.READ MORE >>
Detecting high resistance connections in and between electrical circuits such as bonding and contact resistance can be quick and easy with a low resistance ohmmeter. The digital microhmmeter will enable users to identify high resistance electrical connections and perhaps avoid the undesirable consequences that they could lead to, if left undetected.READ MORE >>
The Vacuum Interrupters CBT-1202 Circuit Breaker Timer is a self-contained, multi-use test set designed to operate and interact with all types of circuit breakers. Incorporating a digital timer to capture and store trip, close and bounce times. It is a handy, field portable test set that incorporates a power supply for energizing the charging motor in spring loaded circuit breakers while outside their cubicle. The CBT-1202 also has provides users with controls for tripping and closing the breaker, and features a unique cable set which speeds and simplifies connections to the breaker under test.
The power supply incorporated in the CBT-1202 provides a 0-120VAC and 0-125VDC output for charging circuit breakers that are spring charged while outside their cubicle. There are also provisions for accepting and distributing variable voltages from an external power supply.
The charging power supply and breaker operational switching are frequently used features even when working on a breaker when the timer function is not required.
The built-in timer records breaker opening, closing and trip times; and 10 test results can be stored in the internal memory.
Unique, pre-wired 15-foot cable assemblies provide simple, fast connection to the circuit breaker under test. In addition to a universal cable set, breaker specific cable sets are also available for testing GE PowerVac (Vacuum Interrupters CBT GE PowerVac Breaker) and Eaton/Westinghouse/Cutler-Hammer VCP-W. Other pre-wired cable sets are available for all types of circuit breakers.
Compact and lightweight, the Vacuum Interrupters CBT-1202 Circuit Breaker Timer is ideally suited for both field and shop use.

Depending on the method of inspection, as well as application and installation, a great deal of time and effort could be invested in verifying the electrical health and integrity of electrical insulation. However, insulation resistance tests can be a relatively quick and effortless method of inspecting insulation. This type of test can be applied to practically any electrical insulation. Test results are recorded, trended, and if appropriate, compared to manufacturer's recommendations or industry standards and guidelines. A good insulator should have a very high resistance to leakage current. Environmental, electrical and mechanical stresses can aid in exploiting voids and the development of microscopic cracks. These phenomenon permit increased access for contaminants to migrate into the insulator or insulating systems. When this happens, there is an increased potential for electrical faults and system failures, which relates to compromised reliability of the electrical system.READ MORE >>

Transformers can sometimes experience significant physical stresses whenever they are moved from one location to another, such as when they are initially shipped from the manufacturer. Once they have been placed into service transformers can also experience tremendous stresses related to being in the path of fault currents when something goes wrong in the electrical system. The combination of mechanical and electrical stress can cause the transformer to prematurely fail. Symptoms may not be obvious until the damage is already extensive. Performing sweep frequency response tests can be used as an early identifier problems that occur as a result of physical changes within the transformer.READ MORE >>
