Digital Meter With LED DisplayDigital meters with LED display enable fast and accurate survey of electric quantities and are convenient for industrial use as well as for the production and distribution of electric energy. They are panel mounted and enable measurement of TRMS values of electric quantities.
Energy Meters With Power DisplayWith Power Display, display instantaneous power in single or three-phase systems with balanced or unbalanced load. Our energy meters with power displays have housing for panel mounting. Some of them can also display momentary power in single and three phase systems with balanced or unbalanced loads.
Analogue MetersActive or Reactive Power MetersPower meters are electronic meters intended for measuring active or reactive power in single phase or three-phase networks, with balanced or unbalanced load. The accuracy class is 1.5. The scale value depends on primary values of current and voltage.
Power Factor MetersPower factor meters are intended for measurement of power factor (cosϕ) in a three-phase three-wire network with a balanced or unbalanced load or in a single phase network. The accuracy class is 1.5.
Pointer frequency meters are intended for measurement of frequencies in the range from 45 Hz to 65 Hz.
Reed frequency meters are intended for measurement of frequencies in the range from 45 Hz to 65 Hz. Two-system reed frequency meters are intended for measurement of two frequencies in the system for synchronisation. Their class is 0.5.
Meter With Limit ContactMI 7350 can signal minimal and maximal setting limits (MINand MAX). The meter is provided with two output relays of600 VA switching power.
TAP Position Indicators monitor the voltage Tap on a transformer, hoist or valve position etc. It employs a bridge system, using a 400Ω or 50Ω per step. The scale is entirely linear and inter-changeable.
Meters for AC Voltage or Current with Moving Coil and a RectifierMeters with a moving coil and a rectifier are intended for measurement of AC currents or voltages where a linear scale is required, in the frequency range from 40 Hz to 65 Hz (higher frequency range on request). The scale is interchangeable. The accuracy class is 1.5.
Meters for AC Voltage or Current with Moving IronMeters with a moving iron are intended for measurement of AC currents or voltages of frequencies from 15 Hz to 100 Hz. They measure rms values independently on the signal form of current or voltage.
Bimetal maximum current meters with a bimetal measuring system are intended for testing the thermal load of transformers, cables, electrical machines, etc. They indicateaverage rms current value in a setting period of 8 minutes (on request 15, 20 and 30 minutes for the MQ0207 and the MQ0307). The accuracy class is 3 and the meters are provided with an interchangeable scale. Meters in the size of 96 x 96 mm with a protecting transformer are also available on request.
Combined Bimetal Maximum Current ValuesCombined bimetal maximum current meters are provided with a built-in bimetal system and a system with a moving iron. The meters are intended for testing momentary and thermal load of transformers, cables, electrical machinery, etc. Meters with dimensions of 96 x 96 mm with a protecting transformer are also available on request. The accuracy class for average rms current value is 3, and for momentary value 1.5. The meters are provided with an interchangeable scale.
Shunts = 50 Millivolt + 60 Millivolt.
Current TransformersCurrent measuring transformers are used for measuring Primary AC currents. The secondary current is 5A or 1A, rated frequency from 50 Hz to 60 Hz.
Surge ArrestorIs a device that will protect electrical equipment from over-voltage caused by external influences, for instance, lightning.•Wenzhou Chuangjie Lightning Protection
Flag RelayThis device will indicate when a circuit breaker has tripped.
If you are looking for manually or semi-automatically synchronise generators and bus bars, you have come to the right place. Our synchronization meters are truly unique products. They measure phase differences between generator and bus bar, voltages and the frequencies of the two systems. They can replace up to five instruments, occupying less space and giving you more information, for a lower price. Furthermore, they are equipped with status output, they are also appropriate for mounting on ships. They are equipped with LED diodes, so you can actually see the phase difference. When synchronising conditions are set, the synchronizing relay is activated.
