Megger MTO106-NL Transformer Ohmmeter

Description

The Megger MTO106-NL is an entry-level, line-operated transformer ohmmeter designed for safe and accurate field measurement of winding resistance. The "-NL" designation indicates that the instrument is sold without accessories, such as test leads.

Key features

• Winding resistance testing: The device is designed to measure winding resistance in smaller transmission and distribution transformers, as well as reactors, motors, and generators.
• Dual channels: It features two channels with a maximum current output of 6 A.
• High test voltage: A 48 V test voltage ensures fast saturation of transformers.
• Wide measurement range: The instrument can measure resistance from 10 µΩ to 30 kΩ, with an accuracy of ±0.25%.
• Intuitive operation: The MTO106 is simple to use, with a single selector switch for the test current and a single button to activate the test cycle.
• Safety features: It includes automatic, passive discharge circuitry that de-energizes the transformer winding at the end of each test, protecting the user and equipment.
• Portability: Housed in a rugged, compact plastic case, the instrument is designed for portability. The closed case is rated IP67, making it suitable for harsh field conditions.
• Power supply: The unit operates on standard AC power (100–240 V AC, 50/60 Hz).
• Dimensions and weight: It measures 360 x 304 x 194 mm (14.2 x 12 x 7.6 inches) and weighs 7.3 kg (16 lbs) without cables.
