Epoxy Resin Outdoor Combined Transformers Indoor or Outdoor Combined Transformers

PRODUCT INTRODUCTION

JLSGW1-10A this combined instrument transformer is for use with electrical measuring instruments and electrical protective devices

PRODUCT DETAILS

JLSGW1-10A this combined instrument transformer is for use with electrical measuring instruments and electrical protective devices. It consists of two current transformers and two voltage transformers in the same case.

Our combined instrument transformer is especially suitable for HV metering, to do so, two voltage transformers shall be connected in V type, while two current transformers connect serially to phase A and C. The instrument transformer can be fixed on the post of transmitting line. The secondary output connects directly to an independent HV metering box. Users can choose certain connection in accordance with different conditions.

Product Feature

This HV measurement set consists of 2 single phase VTs, 2 single phase CTs and 1 surge arresters. The instrument transformers are insulated by outdoor epoxy resin which is suitable for outdoor use. This measurement set is with compact structure, small volume, high accuracy and excellent performance.

In order to meet the requirement of outdoor high voltage metering usage, 2 VTs are in V style connection and 2 CTs are connected serially to phase A and C. There are 2 surge arresters in the power inlet terminal. The voltage loop adopts anti-resonance design, which is rated to increase the primary current by 200% and has strong overload capacity.
