voltage transformer Current Transformer (LQG-0.66B)


This type of current transformer is plastic shell, fully closed structure and indoor using products. For rated frequency is 50Hz or 60Hz and rated below 0.66 KV power system for current and energy measurement. This Products comply with IEC60044-1; 2003 and GB1208-2006 Current Transformer standard.

Useing Condition

1. Altitude ≤ 1000km
2. Ambient temperature ≤ 40centigrade, ≥ -5centigrade
3. Ambient relative air humidity ≤ 85%(20centigrade)
4. Installation site prohibit the following things:
Gas which seriously affecting the insulation transfomer

Steam; Chemical deposition; Contamination

Other explosive or corrosive media

Structure Introduction

This series current transformer is ABS flame-retardant plastic shell fully closed structure, It made the product less susceptible to moisture. Permeability material adopt toroidal core which via annealing testing to ensure products accuracy of 0.2 or 0.5. The application of Superconducting magnetic materials makes the product achieve the same volume level del 0.2 S or 0.5 S plan and Can make the products in a wide current of 1%-120% accurate measurement under load. The primary is P1 \P2, secondry is S1\ S2. When the primary current flows P1 to P2, then the secondary current through the external circuit flows from S1 to S2, is subtractive polarity.

Special remind

When a current is passed, not open the secondary circuit, or high-pressure generation
