1. Application
The rapid development of modern industry, the insulation test of high-voltage equipment puts forward higher requirements, and the traditional measurement methods will face severe tests. With the large-scale application practice of optical fiber in intelligent substation, FTIR-10M 10KV insulation resistance tester has good insulation and anti-interference ability, high measurement accuracy, easy miniaturization, and extremely low failure rate, which has received extensive attention. It is widely used to solve the evaluation of electrical insulation quality of large high-voltage transformers, electric motors, generators, long-distance power cables and tubular busbars under high-voltage substation and power plant on-site strong interference.
EPR50C Digital insulation resistance meter consists of medium and large scale integrated circuits. The output power of the watch is large, and the output voltage level is a lot (with 6 voltage levels). Rated insulation test voltage range 250V ~ 10kV, insulation resistance measurement range 0.01MΩ ~ 2000GΩ. DC voltage measurement range 0 ~ 1000V, AC voltage measurement range 0 ~ 750V.
2. Warns before Use This Insulation Resistance Tester?
For safety, before use the instrument must be well earthed, because the measured target connects to high voltage power, and exists power frequency leakage.
Once high voltage has started, do not use manual discharge method to check the instrument. After test, please wait till the instrument completes automatic discharge and automatically returns to zero, then manual discharge can be operated. That is because electrical pulse caused by short-circuit discharge will damage the insulation life of the measured object; if the pulse fleeing into the instrument, will also damage the integrated circuit inside the instrument.
The instrument is designed for HV substations and power plants to test the characteristic of large HV transformer, electric machines and appliances, remote power cable or buried cable and other electrical insulation resistance in strong interference environment. It also can be widely used for testing characteristics of insulation resistance in other area.
