MIDAS 2881

Mobile Insulation Diagnosis and Analyzing System

The MIDAS 2881 is a portable power factor tester for periodic maintenance and inspection of high voltage insulation losses of electrical apparatus, 

especially in the harsh electrical environments experience in substations and other field locations. 

Designed for testing at local power-line frequency, the MIDAS automatically measures and records dissipation factor (tan δ), power factor (cos ϕ) 

and all other relevant values of impedance. Damage or changes in the insulation material are detected rapidly and reliably. 

* Features

 · Measures Dissipation Factor (tan δ) and Power Factor (cos ϕ) with built-in high voltage supply up to 15 kV, 4 kVA, 15 … 1000 Hz including manual and automatic (sequencer) test operation.

 · Accurate, reliable, rugged, and safe construction with built-in, long-term stable nominal capacitor.

 · Low PD level Due to the state of the art high voltage power supply with filters.

 · Easy to operate including advance measurements like Swap Frequency on Bushings, Short Circuit Impedance and Excitation Current.

 · Stand alone Bridge option with additional measuring capabilities like Quality Factor, Power, Losses, Impedance, Inductance, Reactance, Spectrum Analyzer, Digital Scope and Data Logger.
