General Information

AC Resonant Test System for Substation Electrical Equipment, is mainly composed of variable frequency power,exciting transformers,reactors, capacitive dividers, which designed for AC withstand voltage test of substation electric primary equipment 220kV or below.

Applications

Transformer

GIS system

SF6 switchgear

Cables

Bushing

Insulator

CT/PT

Other capacitive devices

Features

Smaller size,lighter weight compared with same voltage level,same capacity reactor.

Small temperature rise at rated load.Dry type epoxy cast,high mechanical strength,good insulation,nice and reliable.

Adjustable capacity of frequency control source.Strong protection, good stability. With multiple working mode,easy to operate.

With 220V or 380V single phase power,convenient for on-site power sourcing.

Flexible configuration.Different type reactors for optional,meet different test object requirements. Multifunctional ,cost effective.
