MOQ: Not Specified
  Wuhan GDMK Electric Co., Ltd.
Supplier From Wuhan, Survive, China
Supplier Of Zinc Oxide   |   Electric Arresters   |   Electric Components   |   Tools & Instruments
 
Product description

The metal oxide arrester tester is used for the measurement and analysis of metal oxide arrester MOA leakage. It is mainly used for measuring the resistive current to analyze the degree of zinc oxide aging and damp. The field charged test shall conform to Electric Power Industry Standard of the People's DL474.5-92 Guide for Insulation Test on Site - Lightning Arrester Tests. The metal oxide arrester tester can be also used for factory and acceptance tests.



Zinc oxide arrester tester Technical Indexes

Range of reference voltage input peak 10V-200V

Measurement range of full leakage current peak 100uA 10mA

Measurement range of resistive current peak 100uA 10mA

Measurement range of capacitive current peak 100uA 10mA

Measurement range of angle 0-90

Power consumption 4W

System measurement accuracy reading 5 5 words not more than 2m for harmonic current

AC power supply AC 220V 10 50Hz 1



Precautions

When measure the reference voltage from PT or the measuring end of the testing transformer, carefully check wiring to avoid the PT secondary or test voltage short circuit.

Be careful not to wrongly connect the current and voltage sampling lines in the connecting process.

In the laboratory experiment, the high voltage power supply cannot use the series excitation testing transformer.
