TTC-1 Tracking Test Chamber is Designed According to IEC60112-2009

The full name of IEC60112-2009 is <Method for the determination of the proof and the comparative tracking indices of solid insulating materials>. It has been prepared by subcommittee 15E: Methods of test, of IEC technical committee 15: Insulating materials.The following is the original content of IEC60112-2009 Principle.

The upper surface of the test specimen is supported in an approximately horizontal plane and subjected to an electrical stress via two electrodes. The surface between the electrodes is subjected to a succession of drops of electrolyte either until the over-current device operates, or until a persistent flame occurs, or until the test period has elapsed.

The individual tests are of short duration (less than 1 h) with up to 50 or 1 00 drops of about 20 mg of electrolyte falling at 30 s intervals between platinum electrodes, 4 mm apart on the test specimen surface. An a.c. voltage between 1 00 V and 600 V is applied to the electrodes during the test.

During the test, specimens may also erode or soften, thereby allowing the electrodes to penetrate them. The formation of a hole through the test specimen during a test is to be reported together with the hole depth (test specimen thickness). Retests may be made using thicker test specimens, up to a maximum of 1 0 mm.

NOTE The number of drops needed to cause failure by tracking usually increases with decreasing applied voltage and, below a critical value, tracking ceases to occur.

LISUN designed TTC-1 Tracking Test Chamber. Due to the electric stress and electrolytic contamination of the surface. This method simulates tracking currents on insulation material by providing drops between electrodes. During the process of normal use, insulating material may be exposed to moisture and dirt, and may cause stress and fire hazard if it is conductive.

This customer is a leading manufacturer of LED industry in India. The company began to produce and develop LED lamps, power converters, fans, PCB assembly, etc. for railways very early. In addition, all equipment in this customer factory is certified and calibrated to produce high-quality products required by the railway.

This customer learned about our company through our local old customers. When our engineers went to the local area to do installation training for one of our old customers, the customers were very interested when they learned the news and asked to go to the scene to communicate with our engineers. After obtaining the customer's agreement, we invite the customer to watch and answer the technical questions raised by the customer. Customers on-site to see our after-sales service expressed satisfaction. And soon contacted us to place an order for a LSG-1700B goniophotometer and a SG61000-5H surge generator.

We arranged production soon after receiving the customer's order. While we are producing the equipment, our engineers design darkroom drawing according to the dimensions of the darkroom provided by the customer. After customers decorate the darkroom according to our darkroom drawing, their equipment is also completed. Customers apply for our engineers to their factory for installation and training immediately after receiving our equipment. Although it was the first cooperation, the installation and training was also very pleasant and smooth. The following are photos taken by Lisun engineers in the customer's Lab:

The full name of IEC 61000-4-5-2014 is ELECTROMAGNETIC COMPATIBILITY (EMC) –Part 4-5: Testing and measurement techniques Surge immunity test. This part of International Standard has been prepared by subcommittee 77B: High frequency phenomena, and IEC technical Committee 77: Electromagnetic compatibility. The following is the original content of IEC 61000-4-5-2014.

This part of IEC 61000 relates to the immunity requirements, test methods, and range of recommended test levels for equipment with regard to unidirectional surges caused by overvoltages from switching and lightning transients. Several test levels are defined which relate to different environment and installation conditions. These requirements are developed for and are applicable to electrical and electronic equipment.

The object of this standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to surges. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon.

NOTE As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard is applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria. TC 77 and its sub-committees are prepared to co-operate with product committees in the evaluation of the value of particular immunity test levels for their products.

LISUN designed SG61000-5 Surge Generator. The SG61000-5 fully automatic surge generator (lightning surge immunity test) provides a common basis for evaluating the resistance of power cords and internal connectors of different equipment to high energy transient interference caused by natural lightning surge induction and large capacity load switching.
