Thank you for purchasing the product. Before performing on site test, please carefully read the -

instructions in the user manual and make sure you are skilled at operating the product, and please

follow the safety information and precautions listed in the user manual.

 Pay special attention to safety when using the product, especially for measuring circuit with

voltage over AC 100V.

 It is forbidden to test bare conductor or bus bar with voltage over 35kV.

 Insulation stick must be connected if the voltage of measured line is over 600V.

 - On site testing must be performed by authorized trained personnel.

 Please pay attention to the labeled words and symbols at the front and rear panels of the product.

 Do not keep the product in places with high temperature, high moisture, dew or direct sunlight

for a long time.

 Be sure the battery polarity is correct when replacing battery, remove the battery if not used for

a long time.

 Use, disassembling and maintenance must be performed by authorized qualified personnel.

 Avoid impact on the clamp jaws. Perform regular maintenance on the product, do not use

corrosive or coarse material to clean the product, please mildly wipe the product through soft cloth

(i.e. glasses rust dehumidifying lubricant (i.e. WDcloth) dipped with anti- -40).

 Please stop using the product if it poses danger during use.

 The danger symbol “ ” at the product and the user manual identifies that the operator must

perform safe operation according to the instruction.

 The extreme danger symbol “ ” at the user manual identifies that the operator must strictly

perform safe operation according to the instruction.

 It is recommended to perform dielectric test on the product once a year at least (AC 60kV/rms

b etween both ends 5 pieces of connected insulation sticks).

II. Introduction

UT225B High-Voltage Transformer Turns Ratio Tester makes a breakthrough on conventional

structure. It is designed and manufactured to test primary current, secondary current and turns ratio

of transformer below 35kV, and identify phase type and polarity. UT225B consists of primary clamp

sensor (high ge clamp sensor), secondary clamp sensor, tester, high voltage insulation stick, -volta -

monitor software, communication line, etc. The primary clamp sensor can transmit testing data in

a wireless manner, with transmission distance at 100 meters.

Made up of high performance permalloy and designed with magnetic shielding technology, the -

clamp sensor can resist external magnetic fields and continuously perform monitoring with high

accuracy, stability and reliability.

The LCD of the tester can display contents clearly. The tester has an ultra large storage capacity

to store up to 3000 groups of data.

Connected with 5 pieces of insulation sticks, the high voltage clamp sensor can be applied to -

measure current of insulated line below 60kV or high/low voltage bare conductor below 36kV. The -

special automatic plugging structure enables the high voltage clamp sensor to clamp onto or -

remove from the measured conductor easily and fast. The insulation stick is characterized by

lightweight, moisture- - -proof, impact resistant, bending resistant, and highly insulated (insulation

level: 110kV). UT225B is extensively used to inspect current, prevent electricity theft and perform

field electrical operation for substation, power plant, power inspection department, industrial and

mining enterprise, inspection station, and electrical repair department.
