Dual Configuration

Choose between inflatable (SF₆) or dry-type insulation

Simplified Operation

Minimal wiring requirements for fast deployment

Configuration Options

Inflatable Type

• SF₆ gas insulation for high-voltage stability

• Ideal for humid or contaminated environments

Dry-Type

• Solid dielectric insulation

• Lower maintenance in controlled conditions

Typical Applications

• PT Calibration Labs: Reference standard for accuracy testing

• Field Verification: On-site calibration of substation voltage transformers

• Meter Manufacturing: Production-line testing of energy meters

• Power Quality Studies: Harmonic distortion analysis

Operational Advantages

1. One-Person Operation: Lightweight design enables single-operator use
