DESCRIPTION
SPECIFICATION

Yokogawa announces its latest family of Digital Power Meters, the WT300 series. This new addition to Yokogawa’s highly recognized digital power analyzer product line is the 5th generation of its high performance, low cost product group. The WT300 family consists of three models: WT310, WT310HC, WT330. The WT310 is a single phase unit with the capability of measuring low currents from 50 micro-Amps up to 20 Amps RMS. The WT310HC is a single phase high current model with current ranges from 1 Amp to 40 Amps RMS. The WT330 is available as a two element or three element unit for applications on split phase and three phase circuits. This model has current ranges of 0.5 Amps to 20 Amps RMS. All models have voltage ranges from 15 to 600 Volts RMS.

Basic power measurement accuracy (50/60 Hz) : 0.1% of reading + 0.1% of range
Influence of power factor : When power factor ( ) = 0 (S: apparent power) ±0.2% of S for 45 Hz ≤ f ≤ 66 Hz
Frequency bandwidth : DC, 0.5 Hz to 100 kHz (WT310EH DC, 0.5 Hz to 20 kHz)
Direct input Current range : 6 ranges/1 to 40 A
External current input : EX1: 2.5/5/10 [V] EX2: 50 m/100 m/200 m/500 m/1/2 [V] (OP.)
Expansion of effective input range for voltage & current (CF = 6A) : No
Expansion of maximum displaying value for voltage & current (CF = 6A) : No
Frequency measurement : 2 channels (voltage and current)
Sampling rate : Approximately 100 kS/s
Data Update rate : 100 m/250 m/500 m/1/2/5 sec

The Universal Relay Test Set and Commissioning – Omicron CMC356 Essential Package

The CMC 356 is the universal solution for testing all generations and types of protection relays. Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very high power demands. The CMC 356 is the first choice for applications requiring the highest versatility, amplitude and power. Commissioning engineers will particularly appreciate its ability to perform wiring and plausibility checks of current transformers, by using primary injection of high currents from the test set.
