Offered in either power frequency (50/60 Hz) or Very Low Frequency (VLF) models, AC hipots are capable of testing multiple types of substation apparatus, such as; motors/generators, isophase bus, and other loads requiring an AC withstand test.READ MORE >>
The HV Diagnostics TD90-MC 90kV Portable Tan Delta Measurement System is an easy to use, single piece, Digital Signal Processor based, field portable, fully automatic VLF (Very Low Frequency) high voltage measurement instrument developed for the high potential measuring of the insulation dielectrics of various types of electrical apparatus.
The HV Diagnostics TD90-MC is a versatile high voltage tan delta measuring system suitable for testing medium voltage electrical insulation systems such as cables (including: XLPE, PE, EPR, PILC etc.), capacitors, switchgear, transformers, rotating machines, insulators and bushings.READ MORE >>
The HV Diagnostics HVA90 90kV VLF / DC High Voltage Test Instrument features the ability to test MV and Sub Transmission class cables including 69kV cable and below. The HV Diagnostics HVA90 not only produces some of the highest VLF AC voltages available, but it also has a very powerful output capability, facilitating the testing of long cables.
Setup of the HVA90 is simple and automatic with no cumbersome interconnecting of various modules. Automatic test sequences can be setup directly on the instrument or on the supplied HVA Control Center software, and test reports are downloaded to the instrument’s internal memory or to a USB flash drive.READ MORE >>
Weak motor insulation often degrades to the point of causing premature and unexpected motor failure, which in turn can result in costly unplanned downtime of production machinery. The SKF (Baker) 12kV Static Motor Analyzer AWA-IV/12 is a fully-automated motor analyzer that automatically performs repeatable, user-programmable tests to thoroughly assess the strength of a motor’s insulation and circuit. The SKF AWA-IV/12 also used to assure quality of motor rebuilds or new production motors before they are placed into service.READ MORE >>
Over the years there have been several methods and/or philosophies regarding the testing of underground electrical power cable. The Insulated Conductor Committee of the IEEE Power Society has divided these methods or philosophies into two fundamental categories, Type 1 Field Tests and Type 2 Field Tests.READ MORE >>
The purpose of hipot or high potential and voltage testing is to measure isolation to ensure that current cannot flow from an isolated point to another circuit. If the circuits pass the test, it means that there is high resistance for your electrical system to operate properly. This process is to make sure that electrical circuits are safe and won't cause any damage to your home or appliances. Your electrical system will pass this test if there is no leak detected by the cable. Minimal leaks sometimes happen, but the electrician will assess for you if it is still safe or something needs to be repaired.READ MORE >>
vWhen choosing between different models of VLF hipot test equipment, there are a few things to keep in mind. Not only should the system’s specifications be considered such as voltage and power, but attention must also be given to the unit’s actual design, waveform output and maker as well.READ MORE >>
Insulation problems are one cause of electrical equipment damage and electrical fires, an revenue may be lost due to power interruptions and equipment replacements. Avoid these problems through regular preventive maintenance.READ MORE >>
Renting is a smart way to reduce costs on electrical maintenance and clutter in your equipment storage area, because you do not have equipment to keep and maintain. Many think that renting is not reliable in emergency situations because it takes time before you receive equipment. However, there are companies that offer same day delivery so you can immediately do repairs within the day.READ MORE >>
