ZORC surge suppressor

ZORC-MODULE TRANSIENT SURGE SUPPRESSOR

GINO-AKA is a distributor of ZORC modules in France.
ZORC: Zinc - Oxide - Resistor - Capacitor

The ZORC is a unique, high frequency transient overvoltage surge suppressor for the protection of motors, transformers and generators from steep wave-front, short rise-time, high magnitude, spikes, surges, other transient voltages and circuit switching.

Key Features

  • Saves money by eliminating production downtime due to insulation failures
  • Protects motors, generators and transformers throughout their service life
  • Eliminates multiple pre and re-strike transients associated with vacuum and other switchgear
  • Standard and intrinsically safe models available
  • Three and single phase

 

Product Functions

  • System Voltage: 400 V to 40 kV
  • Transient protection: 0.1 to 0.2 micro seconds range
  • Special compact versions that can be fitted within most motor/transformer terminal enclosures or switchgear panels

 

Installation

ZORC surge suppressors may be installed in any orientation (including upside down) on the machine side of the associated medium voltage motor/generator/transformer switch, in the following positions (in order of preferance from a surge protection point-of-view):

  • In the motor/generator/transformer terminal box, connected from each phase to earth.
  • Cabled to the motor/generator/transformer terminal box via a 3-core cable (25 mm² minimum), plus earth conductor (in accordance with local regulations).
  • In line with the motor/generator/transformer supply cable, shunt connected from each phase to earth.
  • In the associated motor/generator/transformer switch panel, connected from each phase to earth.
  • Convenient mounting brackets or clamps are provided.

 

Applications

  • Fans
  • Induction and arc furnaces
  • Mini and mobile substations
  • Compressors
  • Power station auxiliaries
  • Mine winders
  • Crushers
  • Dry type transformers
  • Pumps
  • Motor-generator sets
  • Refrigeration machines
  • Mills
  • Conveyors
  • Generators
