NOVA STS single-tank triple-single recloser

NOVA STS single-tank triple-single recloser

Eaton's Cooper Power series NOVA STS single-tank triple-single recloser consists of three single-phase recloser units in one tank. Each consists of an interrupting module, with embedded CT and mechanism. The interrupter modules utilize outdoor cycloaliphatic-epoxy-encapsulated vacuum interrupters. Suitable for pole or substation mounting, the NOVA STS recloser provides automation of distribution feeders in line applications. The three NOVA STS recloser units are controlled by a single Form 6 recloser control, on a per-phase basis for both source and load that can be programmed for three operating modes.

Operation flexibility

Core features

  • Lower installation and maintenance costs
  • Lower operating costs
  • Improve MAIFI reliability up to 62% for single-phase trip/three-phase lockout performance
  • Improve SAIFI reliability up to 32% for single-phase to ground, line-to-line, and three-phase faults by changing three-phase mode of operation to single-phase mode of operation
  • More compact, lighter unit takes less space on the pole

Easy operation

The Form 6-TS control front panel allows the user to open and close any phase independently without any menu navigation. Each phase of the NOVA STS recloser has a dedicated manual trip lever for quick, on-the-spot, single-phase tripping.

Reduce system costs and improve system reliability

Eaton's Cooper Power series NOVA STS recloser can be programmed to isolate faults on an individual phase basis, even in multiple-fault scenarios. For example, load-side fuse protection is maintained even if two faults occur on different phases prior to resetting the control.
