Gas-Insulated (RMU) Type Transformers
Busbar-type, open (split) construction three-phase current transformer with cast-resin insulation, used as a zero-sequence current transformer. The open body lets it be fitted around existing three-phase conductors without disturbing the primary circuit.
The LSZJ1-10 is a three-phase combined current transformer built for gas-insulated RMU switchgear and pole-mounted switch assemblies.
It provides simultaneous measurement, metering and zero-sequence protection functions from one compact unit, vacuum-cast in epoxy resin.
Zero-sequence ratios 20/1 to 300/5 · 484 × 65 mm overall.
