Udeyraj Electricals Private Limited products

UDEY AC HIPOT TESTERS-US SERIES are AC High voltage break down / withstand voltage testers with digital displays, count-down timer and set trip current facility. These are accurate, durable instruments designed to perform high voltage withstand / breakdown tests on various types of electrical / electronic products, systems and components.

Insulating Oil Testers are designed for the easy and accurate determination of the die-electric strength of insulating oils used in transformers, switchgears, bushings, capacitors and other electrical apparatus. They are ideal for on-site field and laboratory use. Safe and easy operation has made UDEY insulating oil testers the industry standard for more than 55 years.

It is well known that DC testing of aged extruded cable such as XLPE and EPR is potentially damaging to the cable insulation causing premature failure of the cable under service conditions. In addition, DC “proof” or hipot testing has been found to be ineffective in detecting even serious defects in cables. Since this is the main objective of any hipot test, and due to the negative side effects of DC, VLF wave form testing is now recommended by almost all cable testing standards/guides such as IEEE, CENELEC, VDE, SABS etc.Acceptance or maintenance hipot/proof testing using VLF high voltage sinusoidal AC allows the operator to efficiently detect serious cable insulation defects, before they result in an in-service failure, without affecting those healthy sections of the cable that still have remaining service life.

Description: UDEY TRM-11 is a new generation, fully automatic, transformer turns ratio tester designed for measuring ratio, ratio error of single and three phase transformers. The entire test is done automatically and quickly. Operator enters the test parameters and TRM-11 takes over; powers up the voltage, balances the bridge, takes the readings, and displays the results on the LCD screen. Prints test results through its built-in printer. A key feature of the TRM-11 is automatic measure transformer connection group. LV and HV windings are automatically isolated once the measurement is over. True portability is achieved by the lightweight (only 10 kg), single unit design housing the TRM-11. The TRM-11 is encased in an aluminum alloy cabinet.
