Description:

Model DF902A  Automatic 12kV Capacitance & Dissipation Factor Test Set is designed to measure dissipation( Dielectric Loss factor/DF/tgδ) or power factor(PF/cosφ ) in heavy electromagnetic interference environment such as in power plants or substations.

Its main specimens: Power transformer, Distribution transformer, Instrument transformer, Bushings, circuit breakers, Surge arrestors, capacitors, Motors and Generators.

Its test capabilities: Power factor(PF/cosφ), Dielectric Loss factor/DF/tgδ, Capacitance.

 

Product Features:

Fully automatic, easy to use;

All-in-one Structure, Lightweight, rugged & compact, true portability 

High noise suppression based on the frequency conversion and digital filter technique, its test accuracy can be ensured even the ratio of interference current to specimen current is 2:1(200%).

High speed A/D converters, processed by a DSP. self-calibrating, accuracy standard capacitor, ensure Model DF902A high accuracy

l All the input resistance is less than 2 Ohm, the attached capacitance of connection cable is negligible

Designed for various work environments, in the field, in the laboratory, in a test van;

Protections: output protection, input protection, grounded protection, fault protection

Model DF902A has multiple functions:UST / GST /GSTg, all these functions with its main unit

Using an external high voltage power supplies over 12kV or 5A

100 groups of data storage. RS232 is available; Micro-Printer inside

Ultra long life cycle, average 10 years

Multi Language Version available, English, French and Russian
