Compared to the cyclical downturn in coal prices, the mainland power sector is facing a long-term structural problem, and it is neither easy nor possible to bring the sector back to a resilient upturn. Low coal prices on the mainland, once brought the mainland power companies earnings soared, but unfortunately the good times are not always good, the market in the past year, but the mainland power stocks as worthless, the share price fell endlessly. Anyone who wants to take advantage of the low prices to buy power stocks for a rebound is likely to be disappointed, as the power industry is facing four challenges in its operations.

Relay protection tester is a new type of intelligent test instrument, it replaces the previous regulator and phase shifter combination of test tools, has a small size, light weight, high precision, easy to operate and so on. Relay protection tester is now widely used in line protection, main transformer differential protection, excitation control and other fields, substation automation has become the mainstream.
An insulation resistance tester is a tool used to measure the insulation resistance of electrical equipment or wiring. In addition to the regular insulation resistance testing functions, some advanced models of insulation resistance testers also have some hidden functions, the following are a few common hidden functions: 1. Field Strength Measurement Function: This function can measure the strength of electric and magnetic fields. It can help the user to assess whether the electric and magnetic fields around the electrical equipment exceed the safety standards, so as to ensure the safety of the working environment. 2. Temperature Measurement Function: Some insulation resistance testers are equipped with temperature sensors that can measure the temperature of electrical equipment or wiring in real time. This function can help the user to monitor the working temperature of the electrical equipment, find the temperature abnormality in time and take corresponding measures. 3. Data storage and export function: some advanced models of insulation resistance testers can store the measurement data in the internal memory, and support through the USB interface or Bluetooth wireless transmission to export the data to a computer or other devices for analysis and processing. 4. Automatic Maintenance Tip Function: Some insulation resistance testers have automatic maintenance tip function, which can remind the user to carry out routine maintenance and calibration of the instrument according to the time of equipment use or the number of measurements, in order to ensure the accuracy of the test results and the reliability of the instrument. The hidden functions of insulation resistance tester can provide more functions and convenience to help users better maintain and test electrical equipment.
