Applications
sisco phase detector can perform phase tests and phase sequence tests of power lines and substations, with phase verification, phase sequence measurement, and electrical inspection functions. Strong anti-interference performance and is suitable for various electromagnetic field interference occasions. Phase detector is widely used in the power industry, electronic manufacturing, industrial control and other industries.

FAQs
Q1: How does a phase tester work?
A1: When the phase tester is working, the digital signal is sent to the receiving end through the wireless sending module, thereby reducing the interference and error, and greatly improving the working performance of the phase tester. When the phase detector is in use, first hang the transmitter on the conductor of the power grid under test, and then touch the receiving device to another grid conductor to be tested.
Q2: Functions of phase detectors
A2: sisco phase detectors can perform phase sequence detection (positive phase, anti-phase, default phase), live line inspection, simple electrical inspection, fire line identification, default phase judgment, broken line location search, DC line breakpoint detection, and line maintenance.
Q3: Why do you need a phase tester?
A3: If AC power supplies with different phases or phase sequences are paralleled or closed, a large current will be generated, which will cause damage to the generator or electrical equipment, so a phase detector is required for measurement.
Phase verification refers to the use of a tester or other means to check whether the phases and phase sequences of two power sources or loops are the same in the electrical operation of the power system, which means the measurement of the phase difference in the actual operation. Newly built, rebuilt and expanded substations and transmission lines, as well as after the line is overhauled and before power is sent to users, must conduct three-phase circuit phase verification tests. Therefore, a phase tester is required.
Tips: How to choose a phase detector?
- First of all, pay attention to the voltage level of the phase detector. It has 10KV, 35KV, 110KV, 220KV, 500KV, and it should be purchased according to the on-site voltage.
- Because it is an online test, you must pay attention to the withstand voltage of the insulating rod of the phase detector, and the withstand voltage level must be higher than the line voltage.
- Before the test, it is necessary to conduct a self-inspection on the phase detector. If there is no problem in the self-inspection, it can be tested on site.
