Complete Protection and Serviceability

• Compartmental, dead‑front HV (left) and live‑front LV (right) separation with steel barrier for safe, easy access.
• Primary protection: fused, oil‑immersed bayonet expulsion fuses with isolation links and bayonet holders with flapper valve and external drip shield.
• Primary surge protection: (3) 15 kV class elbow surge arrestors (MCOV 12.7 kVrms).
• Secondary protection: fused disconnect switch (FDS) with external handle, 400 A rating.
• Load break capability: three 200 A, 15 kV load‑break switches and 200 A load‑break elbow terminations.
• Tap changer: 5‑position de‑energized tap changer (±2.5% steps) with 200‑A, 15 kV switch—convenient HV front compartment access.
• Pressure relief device, gas sampler valve, and multiple analog indicators (liquid level, temperature, pressure) for safe monitoring and maintenance.
• Provisions for fault indicator, CTs, metering, and auxiliary controls; meter and CT options available.
• Meets numerous IEEE/ANSI/CSA standards and seismic rated for robust, code‑conforming installations.
