In view of the growing number of factors with a disturbing influence on power systems and the ever increasing sensitivity of the devices and installations on the consumer side, simple monitoring criteria such as undervoltage or overcurrent are usually inadequate nowadays. Reliable logging of all the relevant events within the electrical power system calls for the constant observation of a wide variety of derived parameters such as harmonic content, system unbalance or interharmonics and the swift identification of the slightest deviation from the standard state.
In addition to providing pure monitoring functions, modern power system analysing equipment should be capable of logging in full the mode of operation and the interaction of all the component parts of a power supply system.
Only comprehensive and continuous monitoring of the entire power system enables all resources to be used purposively and effectively for the restoration of system operation should a disturbance occur.
In addition, the recorded data provides the planners of electrical installations and protection equipment with an invaluable basis for the extension and optimisation of primary and secondary equipment.
If you are not already convinced of the importance of using a modern power system monitor, you certainly will be as soon as you are confronted with the question of who is liable for system disturbances and who is responsible for meeting the costs involved.

For failure events recording on voltages, currents and logical signals in power networks of home, high, and possibly also very high voltages. It is especially suitable for capturing and identification of random one-shot events in the power mains, such as short-run overvoltages, undervoltages or overcurrents.
Characteristics
- Designed for recording failure events - course of voltages, currents and logical signals in power networks of home, high, possibly also very high, voltages
- Especially suitable for capturing and identification of random one-shot events in the power mains, such as short-run overvoltages, undervoltages or overcurrents
- 3/4 galvanically isolated voltage inputs of 100 V AC and 400 V AC range
- 3/4 current inputs for use of current probes and clamps with voltage output in 0,1 ÷ 3V AC range
- Eight binary logical signals (e.g. protective components' contacts)
- Sampling frequency up to 4 kHz
- Data stored in an exchangeable SRAM memory PC-card (PCMCIA)
- Supply voltage 230 V AC, backuped with a built-in accumulator
- Setting, data visualisation and processing with Cetis32 program
