Product Detail

Description

This tester is an innovative product with a small size, hand-held operation, battery-powered operation, and easy portability.The products are mainly used in the measurement of contact resistance of switch contacts and other micro-ohm resistances, with fast test speed and high accuracy.

Feature

  • Powered by lithium battery, more than 600 tests can be carried out continuously with one charge, and the test process is simple and convenient.

  • The maximum output current is 100A, a variety of currents are optional, and the test range is wide.

  • During 100A test, the longest test time can reach 60 seconds, which can meet various field applications.

  • Wide range and high precision, up to 5mΩ at 100A.

  •  It has perfect open circuit protection, overheating protection and other protection functions.

  • The 6.5.6-inch large industrial-grade high-brightness color LCD screen is still clearly visible in strong sunlight.

  • An optional external printer is available to facilitate data printing.

  • With local storage and USB storage, it is convenient for data preservation.

Method for Automatic Isolation of Customer Equipment Faults by Load Switches in Distribution Networks
Method for Automatic Isolation of Customer Equipment Faults by Load Switches in Distribution Networks
1 OverviewDistribution network safety has long been under - addressed, with its automation lagging substation automation . Using 10 kV intervals of existing substations to set line section points meets future grid needs . Configuration of distribution switches, section switches, and protection must match substation outgoing - line protection for reliability. Fault isolation, self - healing, and restoration are key to distribution automation .Scholars have studied smart distribution network fault

A Novel Detection Method for Stuck Faults in Load Switches
A Novel Detection Method for Stuck Faults in Load Switches
In recent years, as distribution automation advances, load switches see wider use in distribution lines. Yet, mechanical - failure - induced accidents are on the rise, burdening line operation and maintenance.Poor mechanical performance is the main cause of switch faults. Many scholars study large - scale switchgear operation, using methods like coil current detection, vibration signal analysis, switch travel testing, ultrasonic flaw detection, and infrared thermometry. Motor - current - based s

What are the common faults of load switches?
As an on-site maintenance technician, I frequently deal with electrical, mechanical, and insulation faults in load switches. The following outlines fault manifestations, causes, and solutions:I. Electrical Fault Handling(1) Contact HeatingContact heating is mainly caused by poor contact, insufficient pressure, or three-phase asynchrony. When the contact resistance exceeds 1.5 times the initial value, the temperature rise will exceed the standard in a 40℃ environment. For example, the FW4-10 swit

Short-Circuit Fault Analysis of 10kV Puffer-Type Load Switch
Short-Circuit Fault Analysis of 10kV Puffer-Type Load Switch
1. Fault OverviewIn June 2013, a fault occurred in a high - voltage switchgear in operation in a certain urban area, causing a 10kV line to trip. On - site investigation revealed that the faulty switchgear was a pneumatic ring - network high - voltage load switchgear (HXGN2 - 10 type), and the fault characteristic was athree - phase arc short circuit. After isolating the fault and restoring power supply to users, it should be noted that the same type of switchgear in this area, which was put int
