                                                                                                    ETCR9000高低压钳形电流表 使用方法 性能特点 Analysis on the use and performance characteristics of ETCR9000 high and low voltage clamp ammeter

                                                                                                    ETCR9000 high and low voltage clamp ammeter has automatic insertion and removal function, which is specially designed and manufactured for measuring high voltage current. It adopts new CT technology and mask digital integration technology. If not using an insulating rod, it can also be used as a high-precision low-voltage clamp ammeter and leakage current meter, which can accurately measure the current or leakage current of 0.1mA ~ 1000A.

                                                                                                    The innovative integrated design of the ETCR9000 high and low voltage clamp ammeter clamp head and the guide area ensures high accuracy, high reliability and high stability without interruption throughout the year. ETCR9000 high and low voltage clamp ammeter is connected to the insulation rod, which can be used for high voltage line current measurement below 60KV, online current measurement, and also has peak hold, data hold, data storage, infrared transmission and other functions. Its dedicated clamp ammeter can be pushed or pulled out. Insulation rods can be easily clamped or evacuated, which saves time and speed. It is widely used in substations, power plants, industrial and mining enterprises, testing stations, and electrical maintenance departments for current detection and field electrical operations. It can also be used as a high and low voltage ratio tester, that is, the high and low voltage currents of the primary circuit and the secondary circuit are measured separately, and the high and low voltage ratio can be obtained by manual calculation. The insulation rod is light and has the characteristics of moisture resistance, high temperature resistance, impact resistance, bending resistance, high insulation, and scalability.
