Conductive Shield Voltage Transformer (Potential Transformer) for 24 kV 4-Way Switchgear (Also Operation Power Source)

EPF-20FB

This voltage transformer is a single-phase, epoxy-resin-cast medium-voltage potential transformer designed to also function as an operation power source*, specifically paired with 24kV 4-Way Switchgear. It features a high-voltage elbow-type connector on the primary side and includes an internal high-voltage power fuse for protection. The exterior of the voltage transformer is coated with a conductive metal mixture for shielding, and waterproof treatment can be requested for the secondary side. The voltage transformer has a rated burden and accuracy of 600 VA / 3.0 CL.

* Operation power source: In this application, the voltage transformer can also be referred to as a "control power transformer" (CPT), "control transformer" (CTR), "industrial control transformer," or a "machine tool transformer."


About the Product

Specifically designed for 24 kV 4-way switchgear, this medium-voltage single-pole voltage transformer, or potential transformer, features a high-voltage elbow-type connector on the primary side and a built-in high-voltage fuse for protection. Since the exterior of the voltage transformer is coated with a metal conductive mixture for shielding, the necessary distance between the VT (PT) and the panels (or other equipment) is reduced.

Waterproof treatment can be requested for the secondary of the VT. This optional waterproof treatment will allow the VT to continue functioning even if immersed in water below the level of its primary-fuse housing (such as in the case of water accumulation on the street).

Insulated with Araldite® epoxy, this MV voltage transformer (potential transformer) is characterized by excellent water resistance, superior electrical performance, and great reliability, while being lightweight and compact.

Product Features

  • According to IEC or IEEE Standard.
  • Metal conductive coating replaces traditional metal-box for shielding.
  • Compact, space-saving design.
  • Waterproof treatment can be requested for the secondary. This will allow the VT (PT) to continue functioning even if immersed in water below the level of its primary-fuse housing.
  • Built-in primary fuse can be easily replaced.

Suggested Applications

  • Outdoor or indoor electrical distribution panel board.
  • Especially ideal for low-lying and frequently flooded distribution boxes, such as 4-Way switchgear.
