Product Description

The ED0408 Insulator Spark Gap Zero Tester detects the zero value of insulators based on the potential difference at both ends of the insulator. The spark gap is one of the commonly used and simple methods for detecting insulator zero values in our country; generally, spark gaps are fixed. Our company's insulator spark gap zero tester is adjustable in fixed mode based on potential grade, equipped with an adjustable angle measuring head at the top of the operating rod.

Product Features

The ED0408 Insulator Spark Gap Zero Measuring Instrument detects the zero value of insulators based on the potential difference at both ends of the insulator. The spark gap is one of the commonly used and simple methods for detecting insulator zero values in our country; generally, spark gaps are fixed. Our company's insulator spark gap zero measuring instrument features an adjustable fixed design according to potential levels, with an adjustable angle measuring head at the top of the operating rod.

Technical Specifications

Before climbing the pole, connect and adjust the probe gap on the operation rod, maintain a safe distance from the rod, and secure your safety belt for the inspection work. During the inspection of insulators, the probe contacts the steel caps or metal at both ends of the insulator. If the insulator has good insulation properties, a spark will be produced from the gap discharge, accompanied by a discharge sound and light indicator. If the insulator is defective (low value or zero value), the potential difference across the insulator is very small or zero, and no spark gap discharge will occur, meaning there will be no discharge sound or light indicator. Such porcelain bottles are considered zero or low value and should be replaced immediately.

Note: The adjustment gaps for various voltage levels are listed in the table.
