Description

Product Overview

JSZV16-12R voltage transformer, epoxy resin casting and full enclosed construction, is used indoor for measuring current, electric energy and protective relaying in single-phase or three-phase AC circuit with the frequency 50Hz or 60Hz and highest voltage for equipement 12kV.

The product has the feature of high reliability, low magnetism of core, large creepage distance of external insulation and maintenance free etc.

Key Features

  • Precise Adaptation to 12kV Rated Voltage:Specifically designed for 12kV medium-voltage power grids, it features a voltage ratio error ≤0.2% and phase difference ≤10', meeting the 0.2-class metering accuracy requirement. It provides reliable voltage signals for relay protection and energy metering devices, ensuring the accuracy of grid monitoring data.
  • Built-in Fuse for Overvoltage Protection:Integrates a high-voltage current-limiting fuse that quickly cuts off the circuit within 0.1 seconds during system overvoltage (e.g., lightning strikes, switching overvoltage), preventing damage to the voltage transformer and downstream equipment. Certified to IEC 60282-1 explosion-proof standards, it ensures operational safety.
  • Epoxy Resin Fully Enclosed Casting Structure:Adopts a vacuum epoxy resin casting process to form a fully sealed insulation system with an IP65 protection rating, effectively resisting dust, moisture, and salt fog. Suitable for humid coastal and dusty industrial environments, its maintenance-free design reduces O&M costs.
  • Stable Operation in Wide Temperature Range:Operates within -40℃~+70℃, using high/low-temperature resistant insulation materials to maintain stable electrical performance in extreme climates, avoiding insulation aging caused by temperature fluctuations and extending service life to over 30 years.
  • Anti-fouling Flashover & High Insulation Design:With external insulation creepage distance ≥31mm/kV, equipped with anti-fouling flashover skirts and hydrophobic coatings, suitable for Class Ⅲ pollution areas. Partial discharge ≤5pC, passing 12kV/42kV/75kV power frequency/impulse withstand voltage tests to ensure insulation reliability.

Main technical parameter

  • Highest voltage for equipment: 12kV
  • Rated primary voltage: 11kV
  • Rated secondary voltage: 100/220V or 110/220V or 100V or 110V.
  • Technical standard accords with IEC 60044-2:2003 Part2 Instrument transformers-Part2: inductive voltage transformers

Remarks: Upon request we are glad to offer transformers according to other standards or with non-standard technical specs.
