DESCRIPTION
SPECIFICATION

Megger TTR100-1 is a handheld, robust, lightweight and battery operated instrument. This TTR will complement several existing Megger transformer test products and will offer functions, such as winding resistance and polarity. These functions, as well as the phase angle measurement function, can be switched off when not required. With a turn ratio of 20,000:1, the TTR100-1 offers the highest turns ratio accuracy in the industry of 0.1%. The TTR100-1 features special software capabilities. The TTR100-1 is used to perform final test and calibration of transformers in the manufacturing process, such as a QA or Test Department. Using the new TTR100-1 in this environment will improve the productivity of such QA testing, as well as efficiently collect and store large amounts of data, which can be uploaded to a PC spreadsheet, or database program.

The Universal Relay Test Set and Commissioning – Omicron CMC356 Essential Package

The CMC 356 is the universal solution for testing all generations and types of protection relays. Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very high power demands. The CMC 356 is the first choice for applications requiring the highest versatility, amplitude and power. Commissioning engineers will particularly appreciate its ability to perform wiring and plausibility checks of current transformers, by using primary injection of high currents from the test set.
